Podcasts about Summer Triangle

Based on how bright the stars look to our eyes alone, Deneb ranks among the 20 brightest stars in the night sky. Because the stars are at different distances, though, that ranking is a little misleading. If we could arrange them based on their true brightness, Deneb would outshine them all. In fact, it might be the brightest of all the stars that are easily visible to the unaided eye. Deneb is high in the east-northeast at nightfall, at the lower left corner of the bright Summer Triangle. Deneb is a blue supergiant – it’s much bigger, heavier, and hotter than the Sun. And it’s much, much brighter. Exactly how much brighter isn’t certain. That’s because there’s disagreement about the star’s distance. Astronomers have measured the distance with several techniques. Some are more direct, while others are based on models of different types of stars. That’s yielded estimates of about 1400 to 2600 light-years. And that makes a big difference. At the greater distance, Deneb would be almost four times brighter than at the smaller one. So Deneb’s true luminosity – the value when you add up all wavelengths of light – is somewhere between 50,000 and 200,000 times the Sun’s. If the high end of that range is correct, then Deneb is one of the brighter stars in the entire galaxy – and perhaps the brightest star that’s easily seen with the eye alone.

Altair is a close neighbor – just 16.7 light-years away. Only about 50 star systems are closer. And it’s bigger and brighter than the Sun, so it’s easy to study. Even so, not even the largest individual telescopes can see it as more than a bright dot. Yet astronomers have managed to take a fairly detailed picture of it. They’ve done so with a technique known as interferometry. It combines the views from several fairly small telescopes that are linked together. That reveals as much detail as a single giant telescope. Just how much detail depends on the number and size of the telescopes, and how far apart they’re spaced. The setup doesn’t necessarily see fainter stars and galaxies, but it does see the universe with greater clarity. With conventional telescopes, astronomers had found that Altair spins in a hurry – once every eight hours, versus about 25 days for the Sun. That suggested the star was flattened. They measured that flattening with an interferometer; the star is about 25 percent wider through the equator than through the poles. A few years later, they confirmed that it’s cooler and darker around the equator. And in 2006, they even took a picture of Altair – the first detailed image of any Sun-like star. Altair is high in the southeast at nightfall, at the lower right corner of the bright Summer Triangle. We’ll talk about another member of the triangle tomorrow. Script by Damond Benningfield

A bright Moon is a beautiful sight – unless you have your heart set on seeing the stars. In that case, it’s a pest. The Moon’s glare overpowers many of the stars in the sky. But some manage to shine through even the brightest moonlight. Tonight, for example, even though the Moon is about 95 percent full, three stars are quite easy to find: Vega, Deneb, and Altair – the Summer Triangle. The triangle stands high in the eastern sky at nightfall, and climbs directly overhead later on. Its brightest member is Vega, at the top of the triangle. It’s about 25 light-years away. That means the light you see from the star tonight began its trek across the galaxy in the year 2000. Vega is bigger and heavier than the Sun, and almost 50 times brighter. Deneb is to the lower left of Vega. Its distance is uncertain; more about that tomorrow. What is certain is that it’s a supergiant – many times bigger and more massive than the Sun, and tens of thousands of times brighter. And its fate is pretty well known, too: Deneb is likely to explode as a supernova sometime in the next few million years. Altair is farther to the lower right of Vega. It’s the closest member of the triangle – just 17 light-years away. It’s a lot like Vega, just not quite as impressive. Still, it’s easy to spot through the moonlight – a member of the bright Summer Triangle. Script by Damond Benningfield

Mercury heads to inferior conjunction. Mars gets close to Zavijava. The teapot's on the meridian at dusk. Venus reaches Castor's feet in pursuit of Jupiter. And a couple of big geometry figures are starting points for many beginning astronomers.

The northernmost star in the Summer Triangle is Deneb, which marks the tail of Cygnus the Swan.

Geoff Clayton is the Interim Director of Astronomy at the Maria Mitchell Association. This week Geoff talks about the Summer Triangle, three bright stars in the summer night sky.

Late-October evenings are great for skywatching. The nights are fairly long and cool. And there’s a lot to see. The Summer Triangle is still high in the west, and Taurus is climbing into view in the east. And this year, three planets are visible before midnight: Venus, Saturn, and Jupiter. One thing that’s not visible for the next few evenings is the Moon. It doesn’t rise until the wee hours of the morning. So if you can get away from city lights, you should be treated to a beautiful view of the stars. Dark skies are especially important for astronomers, allowing them to see deeper into the universe. But other things can limit the view. That includes clouds – not just on Earth, but in the stars. Dust is sprinkled between the stars. And the farther you look, the more dust gets in the way. That obscuring effect is known as extinction. Astronomers have to account for it when they measure an object’s brightness, its color, and more. In some cases, they’re looking through a fairly uniform scattering of dust. But in others, they’re looking through dense clouds, which make it really tough to see what’s beyond. Another concern is called seeing – the stability of the atmosphere. If the air is calm, the seeing is pretty good. But if it’s turbulent, it smears the view of the stars. Bad seeing makes the stars twinkle more fiercely. That’s a beautiful effect for casual skywatchers, but bad for astronomers. Script by Damond Benningfield

Each season has a notable constellation or group of stars that can serve as a guidepost to that part of the sky. In summer it's common to use the Summer Triangle and in autumn we have the Great Square of Pegasus.

In many ways, fall has already arrived. The fall term has started for schools. Football season is underway. And September 1st marks the beginning of the fall weather season. Astronomical fall catches up to them tomorrow. Autumn officially arrives at 7:44 a.m. Central Daylight Time – the moment of the fall equinox. The change in seasons occurs as the Sun crosses the equator from north to south. The Sun rises due east and sets due west as seen from the entire planet. And the length of day and night are about equal. That balance won’t last long. In the northern hemisphere, the days will grow shorter and the nights longer until we reach the winter solstice, in December. As that happens, the sunrise and sunset points will slide southward. As the season changes, so do the stars. At nightfall, Arcturus, the brightest star of summer nights, is dropping lower in the west. The signature star pattern of the season, the Summer Triangle, is moving to the western side of the sky. And the scorpion is getting ready to disappear in the southwest. In the meantime, the Great Square of Pegasus is in the east at nightfall, ready to climb high across the sky during the night. Constellations associated with the flying horse are moving into view as well. And so are the constellations of the Celestial Sea – water-related constellations like the fish, the sea goat, and the water boy – stellar sights for the longer nights of autumn. Script by Damond Benningfield

The stars of the Summer Triangle look a lot alike. Vega, Deneb, and Altair are among the 20 brightest stars in the night sky, and they all shine almost pure white. Vega and Altair really are alike. But except for the way it looks to our eyes, Deneb is nothing like the other two. The triangle is high in the eastern sky at nightfall. It’s easy to see even through the glare of the almost-full Moon. Vega is the highest and brightest of the three stars. Deneb stands to the lower left of Vega, with Altair farther to the lower right. Vega and Altair are both about twice the size and mass of the Sun, and a good bit brighter. And both of them spin rapidly – so fast that they bulge outward at the equator. Vega is farther along in its evolution than Altair is. Because of their mass, both stars will spend about a billion years in the “prime” phase of life. That’s compared to about 10 billion years for the Sun. Deneb is a supergiant – one of the bigger and heavier stars in the galaxy. Some of its details are unclear because its distance is uncertain. It could be about 1500 light-years away, or about 2600. Either way, we know that it’s about 20 times the mass of the Sun, and up to 200 thousand times the Sun’s brightness. It’s no more than 10 million years old, with almost no time left. Before long, it’ll explode as a supernova, then fade away – and the Summer Triangle will disappear. Script by Damond Benningfield

After dusk, look about a third of the way up the eastern sky for Altair, the brightest star in Aquila the Eagle and part of the Summer Triangle.

Producer/Host: R.W. Estela Hi, I'm RW Estela: Since 1991, I've been presenting A Word in Edgewise, WERU's longest-running short feature, a veritable almanac of worldly and heavenly happenings, a confluence of 21st-century life in its myriad manifestations, international and domestic, cosmopolitan and rural, often revealing, as the French say, the more things change, the more they stay the same — though not always! Sometimes in addressing issues affecting our day-to-day lives, in this age of vagary and ambiguity, when chronological time is punctuated elliptically, things can quickly turn edgy and controversial, as we search for understanding amid our dialectic. Tune in Monday mornings at 7:30 a.m. for an exciting journey through space and time with a few notable birthdays thrown in for good measure during A Word in Edgewise . . . About the host: RW Estela was raised as a first-generation American in Colorado by a German mother and a Corsican-Basque father who would become a three-war veteran for the US Army, so RW was naturally a military brat and later engaged in various Vietnam-era civil-service adventures before paying his way through college by skiing for the University of Colorado, playing Boulder coffeehouses, and teaching. He has climbed all of Colorado's Fourteeners; found work as an FAA-certificated commercial pilot, a California-licensed building contractor, a publishing editor, a practitioner of Aikido, and a college professor of English; among his many interdisciplinary pursuits are the design and building of Terrell Residence Library (recently renamed the Terrell House Permaculture Living & Learning Center at the University of Maine), writing Building It In Two Languages (a bilingual dictionary of construction terminology), aerial photo documentation of two dam removals (Great Works and Veazie) on the Penobscot River, and once a week since 1991 drafting an installment of A Word In Edgewise, his essay series addressing issues affecting our day-to-day lives — and WERU's oldest continuous short feature. When pandemics do not interfere, he does the Triple Crown of Maine open-water ocean swims (Peaks to Portland, Islesboro Crossing, and Nubble Light Challenge) and the Whitewater Downriver Point Series of the Maine Canoe and Kayak Racing Organization. RW is the father of two and the grandfather of three and lives with his partner Kathleen of 37 years and their two Maine Coons in Orono.

As we head through the middle part of the year, Ian Brannan and Director of Astronomy Dan Pye look at the Summer Triangle, a collection of constellation which take centre stage in the night sky at this time of year. We also discuss the discovery of frost on Mars, which has been found at the top of the biggest mountain in the Solar System Olympus Mons, which is 3x bigger than Mount Everest! And we look ahead to a potential comet with could be visible this autumn! For more news and info visit kielderobservatory.orgSee omnystudio.com/listener for privacy information.

Naija Bruckner an NSF Research Experiences for Undergraduates fellow at the Maria Mitchell Association discusses The Summer Triangle. The Summer Triangle consists of three bright stars that are prominent in the summer night sky and can help to locate the band of our Milky Way Galaxy.

Now that summer has arrived, the famous “Summer Triangle” of stars has returned to guide us around the evening sky.

If you're ready for a taste of summer, look no farther than the dawn sky. The constellations in view at first light are just what you'll see as night falls in July and August. Scorpius is low in the south, with Sagittarius in the southeast. The Big Dipper hangs from its handle in the northwest. And the Summer Triangle — the stars Vega, Deneb, and Altair — stands high in the east. As Earth orbits the Sun, our viewing angle on the stars changes. As a result, each star rises about four minutes earlier each night. So a star that rises at dawn now, will rise eight hours earlier in July, 10 hours earlier in August, and 12 hours earlier in September. Now you might think this all means that we'd see the current morning configuration 12 hours earlier in the night during September — half a year from now. And you'd be partially right. The same configuration of stars will be in the sky at that hour. But the Sun sets later then, so it's still daylight when the stars stand in their current dawn positions. So by sunset then, Scorpius and the others will have rotated farther to the west. That means the best time to see this setup in the early evening sky is a month or two earlier — July and August. That all sounds a bit confusing, but trust us: The stars have been following that pattern for a long time — moving the same stars we see in the dawn sky now into the evening sky during the short nights of summer.

The Summer Triangle is a useful guidepost to many interesting deep sky objects, but it's also a way to find other constellations nearby, such as Delphinus the Dolphin.

If you can escape the glow of city lights, this is a great evening to watch the Milky Way. It forms a hazy band of light that stretches high across the sky. It arcs from Scorpius and Sagittarius in the south; through the Summer Triangle, high overhead; then down to W-shaped Cassiopeia, in the northeast. That band of light is the glow of millions of stars in the disk of the Milky Way Galaxy. If we could view the galaxy from afar, we'd see several bright, beautiful spiral arms wrapping through the disk. The arms aren't permanent structures. Stars that are closer to the center of the galaxy take less time to complete an orbit than stars that are farther out. So if an arm was a permanent structure, it would either rip itself apart or wrap tighter and tighter around the galaxy's core. Instead, each arm may represent the crest of a wave. The wave circles around the galaxy like a wave of water on the ocean. In a galaxy, the wave squeezes giant clouds of gas and dust ahead of it. The clouds then give birth to new stars. Many of the stars are big, heavy, and bright, so they help outline the spiral arms. A wave also carries along lots of smaller stars, enhancing the spiral arm even more. As the wave moves along, it compresses a new region of the galaxy. The stars in its wake spread out, and the brightest of them quickly expire. But new stars take their place — riding a wave through our beautiful galactic home.|  Script by Damond Benningfield Support McDonald Observatory

Join Fiona Powers Ozyurt of the Maria Mitchell Association as she discusses the Summer Triangle. To find the Summer Triangle, head outside after 9pm, look directly overhead and locate the bright star Vega in the constellation Lyra. Neighboring Vega are two other bright stars, Deneb in Cygnus and Altair in Aquila, which together with Vega form a large triangle. This is the Summer Triangle asterism. 

Astronomer Howard Parkin explains what we should be looking for in our August dark skies - including the Summer Triangle, a full Blue Super Moon (that might actually be red!), the appearance of Jupiter and the possibility of a dramatic Perseid Meteor Shower. The music break is Good Morning, Starshine by Oliver and after that, Howard brings us up to date with some of the top stories about the race into space. Howard welcomes questions, and suggestions for stargazing or space-related topics for future programmes - email howardparkin@manx,net

After going over the definitions of a constellation and an asterism, some sky events, and some news items, we will discuss a few of the differences between official constellations and helpful asterisms. Tim and Terry discuss just what the Big and Little Dippers are, as well as the Summer Triangle and how they fit into the night sky picture, as well as some other popular star patterns.

As evening twilight fades into night, look for three bright stars high in the east that form a giant triangle in the sky. The Summer Triangle is a great way to “star hop” to areas of interest.

Aquila, the eagle, spreads its wings across the evening sky. It's well up in the east as the sky gets dark. Its brightest star, Altair, is at the bottom right point of the wide-spread Summer Triangle. Altair represents the eagle's breast, with the wings above and below. A pair of stars at one of the wingtips faces an uncertain future. Early studies said the two stars will ram together and explode as a supernova -- in 700 million years. But more recent work says they won't. Henize 2-428 consists of two white dwarfs -- the dead cores of once-normal stars. They probably started out as fairly massive stars. As the main star aged, it dumped most of its gas onto its companion. As that star aged, it began dumping gas as well, forming a cloud around both stars. The gas was kicked out into space, forming a colorful nebula around the pair. Today, the stars are so close that they orbit each other once every four hours. As they orbit, they radiate gravitational waves, causing them to spiral even closer -- and eventually merge. The early work said the combined mass of the two stars would exceed the weight limit for white dwarfs. As a result, they'd blast themselves to bits as a supernova. But the more recent work said the stars are less massive than originally thought. If that's true, then their merger will be much less spectacular. Henize 2-428 will survive -- as a heavy stellar “corpse” floating through the galaxy unnoticed.  Script by Damond Benningfield Support McDonald Observatory

The Sun is pretty big as stars go — bigger than perhaps 80 or 90 percent of the stars in the entire Milky Way Galaxy. To get an idea of just how big, consider this: At the speed of a jet airliner, it would take about seven months to circle all the way around the Sun's equator. But if you really want to rack up the frequent-flier miles, try circling around the star at the tail of Cygnus, the swan. Deneb is a white supergiant. The “white” designation means that its surface is thousands of degrees hotter than the Sun's. And the “supergiant” designation means that it's one of the biggest stars in the galaxy. In fact, it could be 200 times the diameter of the Sun. So even at the pace of a typical airliner, it would take more than a century to circle Deneb's equator. One problem you might have is deciding just where the star's “surface” is. Supergiants are so puffed up that their outermost layers of gas are quite thin. And Deneb is blowing a powerful “wind” of material out into space, which makes it even harder to tell where the star ends and space begins. But from our distance of 2600 light-years or so, that's not a problem — Deneb looks like a sharp little point of light. It's in the northeast at nightfall, at the left point of the bright Summer Triangle. And the rest of the swan stretches to its right, with the body roughly parallel to the horizon and the wings spread above and below. Tomorrow: An ancient stellar family.  Script by Damond Benningfield Support McDonald Observatory

Join Fiona Powers Ozyurt of the Maria Mitchell Association as she discusses the constellation Aquila. To find Aquila, head outside after 10pm and look in the East direction. Now locate the bright star Vega in the constellation Lyra. Neighboring Vega are two other bright stars, Deneb in Cygnus and Altair in Aquila, which together with Vega form a large triangle. This is the Summer Triangle asterism. 

WATCH this on YouTube LISTEN as a podcast on Podbean, Stitcher, or iTunes Social Media: @mrwebbpv on Twitter and Instagram @pvplanetarium on Facebook, Twitter, and Instagram            Venus shines bright at sunset all month, with Mars nearby, while Saturn, Jupiter, and even Mercury shine in the mornings, and the Beehive Cluster gets two wandering guests, all in the solstice month of June.          Welcome to Observing With Webb, where a high school astronomy teacher tells you what you're looking at, why it's so cool, and what you should check out later this month…at night.    Naked-eye PLANETS Sunset Venus – Look W after sunset. It'll be the brightest object and probably the first “star” you'll see, about 30˚ above the horizon. Sets between midnight and 11pm.  Get your looks in now, because once August starts, your view of Venus in the evening will disappear, and return to the mornings of September. Mars – Look W and about 5 or 10˚ up and to the left of Venus, for a dull reddish dot in the sky, hanging out in Cancer, and slowing moving toward Leo. Sets between midnight and 11pm. Throughout the night - None Morning – (from left to right) Mercury, Jupiter, Saturn Saturn – Beginning of the month: Rises at 1:30am in the ESE, and is 30˚ above the SE horizon by dawn. End of the month: Rises at 11:30pm in the ESE, and is 40˚ above the S horizon at dawn.  About 60˚ to the right of Jupiter. Jupiter – Beginning of the month: Rises at 4am in the E, and is just 15˚ above the E horizon by dawn. End of the month: Rises at 2am in the E, and is 35˚ above the E horizon at dawn.  About 60˚ to the left of Saturn. Mercury – For the first 3 weeks of June, Mercury is less than 10˚ above the horizon, to the left of East. Hard to find, but not impossible.   EVENTS Full Moon – 3rd (Visible all night) Waning Gibbous (Mostly lit, rises later at night) Last Quarter Moon – 10th (Visible midnight into the morning) Morning Crescents (look East in the AM) New Moon – 17th (darkest skies) Evening Crescents (look West after Sunset) First Quarter Moon – 26th (Visible until midnight) Evening Gibbous (Mostly lit, after Sunset)   2nd – Mars, Beehive Cluster (M44) – Find that dull red dot in the sky which is Mars, then take some binoculars out, or a telescope, and witness Mars being directly in M44, the Beehive Cluster, so named because of its resemblance to a swarm of bees. The day before and after, Mars will be on either side of the cluster. Definitely worth at least a look, if not a picture. 9th + 10th – CLOSE ENCOUNTER - Moon, Saturn – Get up early, look SE, and find a gibbous Moon with Saturn about 8˚ above and to the left on the morning on the 9th.  On the 10th, the Moon will have moved to be 7˚ down and to the left of Saturn. 13th – Venus, Beehive Cluster (M44) – Find that bright brilliant dot in the sky which is Venus, then take some binoculars out, or a telescope, and witness Venus being ALMOST directly in M44, the Beehive Cluster. The day before and after, Venus will be on either side of the cluster. Definitely worth at least a look, if not a picture. 14th – CLOSE ENCOUNTER - Moon, Jupiter – Get up early, after 3am, look E, and find a very thin crescent Moon with bright Jupiter only 2˚ to right. 21st – Summer Solstice – This is the longest day of the year in the Northern Hemisphere.  There's a bit of explanation as to why here. 20th – 22nd – CLOSE ENCOUNTER – Moon, Venus, Mars – Check this out right after sunset! Look West and you'll easily see Venus being super bright. Each day, Mars will be about 5˚ (or three finger-widths) up and to the left of Venus.  The best part is the Moon traveling through.  On the 20th, a super-duper thin Moon will be about 13˚ down and to the right of Venus.  But on the 21st, the Moon moves to be just 3˚ to the right of Venus, and is a little bigger and easier to spot.  Then, on the 22nd, the Moon moves up and to the left again, forming a nice curved line with Mars and Venus.  Definitely worth a look, though pictures will prove to be difficult, given the relative brightness of each object.   CONSTELLATIONS... Use a sky map from www.skymaps.com to help you out. After Dinner, Before Bed: Spring Constellations: Big Dipper, Bootes, Virgo, Corona Borealis, Hercules – Gaze almost vertically as you face the NW, and you'll easily find the Big Dipper: seven very bright stars that form a spoon shape. Now if you take the handle of the Dipper, follow its curve to the next bright star you see, about 20˚ away, which is Arcturus. “Follow the arc to Arcturus.” That's the brightest star in Bootes, which looks like a kite. Take that same curve, and follow it about another 20˚ to “speed on to Spica”, the brightest star in Virgo, one of my favorite constellations, since it reminds me of the Dickinson Mermaid.  Now go back to Bootes, and just to the left of Bootes are seven stars that form the northern crown Corona Borealis, which looks more like a small bowl or a “C” in the sky. Continue a little further to the left and you'll find the keystone asterism which is part of the constellation Hercules. Extra Challenge! Look for M13, the Hercules Cluster in between two of Hercules' “keystone” stars.  It known as the best globular cluster in the northern skies.  It will be a fuzzy spot in binoculars and will be even cooler through a telescope Summer Constellations: Lyra, Cygnus, Aquila – Look pretty much straight above you, and find the brightest star up there. You'll notice a parallelogram attached to it. This is the brightest star Vega, part of the constellation Lyra, the harp. Directly above you will be Cygnus the Swan, with its brightest star Deneb. It will look like a large cross, or if you look out a little further, a swan flying above you. Below Cygnus and Lyra is the third constellation of the Summer Triangle, Aquila the Eagle, with its brightest star Altair. The three bright stars in this one can be easily confused for Orion's belt, given their similar size, however they are not in line as straight, and are part of a bigger diamond shape.  Use a star chart to find small Delphinus and Sagitta in the area as well. Before Work: Pegasus, Andromeda – Look directly south and most of the way up the sky and you'll find the very big and almost perfect square of Pegasus, the winged horse. Now if you look to the top left of the square, you'll see three pairs of stars creating a neat double curve to the left and up from that corner star. That is Andromeda. If you have a little extra time, find the middle pair of stars, connect them with a line, and move toward the inside of the curve about the same distance as those stars are apart. There you'll find the Andromeda Galaxy, which will be just a small faint fuzzy with your naked eye. The cool part is that you are looking at billions of stars that are 2.9 million light years away, that spread out about 150,000 light years across.

Each season has a notable constellation or group of stars that can serve as a guidepost to that part of the sky. In summer it's common to use The Summer Triangle, but in autumn we have “The Great Square of Pegasus.”

Summer ended almost a month ago, but some of the stars of summer are still hanging around. And some of them will remain in view until well into winter. On the other hand, a few others are taking their final bows. Scorpius, for example, is quite low in the sky as darkness falls. Some of the stars that outline its curving body have dropped below the horizon by then, and some others are so faint that you can't really see them. Its bright heart, Antares, should be visible for a few days longer, in the southwest. But it's so low that you need a clear horizon to spot it. Sagittarius, the archer, stands to the upper left of Scorpius. Some of its bright stars form the outline of a teapot. It's tilted to the right, as though pouring its brew onto the scorpion's tail. It will linger until around Thanksgiving. Arcturus, the brightest star of Boötes the herdsman, is dropping lower in the west, but it, too, should remain visible through the end of the month. After that, the only holdout is a star pattern named for the season: the Summer Triangle. Right now, it stands directly overhead as night falls, marked by the bright stars Vega, Deneb, and Altair. Because of their high northern latitudes, the stars are in view in the evening sky most nights of the year. And all three will remain in view well into January — bringing a bit of summer to the night skies of winter.  Script by Damond Benningfield Support McDonald Observatory

The Summer Triangle is a useful guidepost to many interesting deep sky objects, but it's also a way to find other constellations nearby. For example, a popular little pattern among stargazers is Delphinus the Dolphin.

September skies bring the lovely Summer Triangle asterism into prime position after nightfall for observers in the Northern Hemisphere. Its position high in the sky may make it difficult for some to observe its member stars comfortably, since looking straight up while standing can be hard on one's neck! While that isn't much of a problem for those that just want to quickly spot its brightest stars and member constellations, this difficulty can prevent folks from seeing some of the lesser known and dimmer star patterns scattered around its informal borders.

Many of the bright stars that decorate the night sky fit a similar profile. They're roughly twice the size and mass of the Sun, a couple of dozen times its brightness, and only a fraction of its age. The list includes two of the stars of the Summer Triangle, which is high in the sky at nightfall, and the five middle stars of the Big Dipper, which is in the northwest. Another star that fits the profile is in Lacerta, the lizard, which is half way up the northeastern sky. The faint little constellation's brightest star is Alpha Lacertae. It's about a hundred light-years away — far enough to dim some of its luster, so you need dark skies to see it. Like the other stars that fit this profile, Alpha Lacertae is class “A.” That's based on its surface temperature, which is thousands of degrees higher than the surface of the Sun. At that temperature, the star shines pure white. Alpha Lacertae is about 400 million years old — just one-tenth the age of the Sun. It won't live nearly as long as the Sun will, because it's more than twice as massive as the Sun. Its gravity squeezes its core tightly, revving up its nuclear reactions. So Alpha Lacertae will live a “normal” lifetime of only a couple of billion years, versus about 10 billion years for the Sun. After that, it'll cast its outer layers into space, briefly surrounding its dead core with a bubble of gas — bringing its fairly short life to a colorful end.  Script by Damond Benningfield Support McDonald Observatory

The swan climbs high across the southern sky on summer nights. It's marked by its bright tail, the star Deneb. It's the lower left point of the wide-spread Summer Triangle. The swan's body angles to the upper right of Deneb, as though the swan were taking flight from a pond. Its long, graceful wings flank its body. The brightest star of the top wing is Delta Cygni. It's a system of at least three stars. Two of them are a good bit bigger, brighter, and heavier than the Sun, while the third is less massive than the Sun. The heavier stars orbit each other at an average distance of almost 15 billion miles — roughly 150 times the distance from Earth to the Sun. But the little guy is much farther out. It's possible that when the system was born, the third star was closer in. But as the stars danced their complex orbital ballet, they swapped some of their energy. The lightweight star was pushed outward, while the heavier stars spiraled closer together. Those stars were pushed into a stretched-out orbit that looks a bit like an oval racetrack. It takes the two stars almost 800 years to make one lap around the track. But the lonely third member of the trio needs more time. It takes many thousands of years to orbit its brighter companions. Look for Delta Cygni above Deneb as darkness falls. It's about a third of the way up from Deneb to brilliant Vega, the brightest member of the Summer Triangle.  Script by Damond Benningfield Support McDonald Observatory

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. Welcome to Episode 242 of the Actual Astronomy Podcast observing in the toybox constellations. I'm Chris and joining me is Shane. We are amateur astronomers who love looking up at the night sky and this podcast is for anyone who likes going out under the stars.    So a long time ago I read an online article about how all these little constellations Vulpecula, Sagitta, Delphinus and Equuleus were referred to as the Summer Toybox (sometimes Lyra is thrown in for it's small stature) but it never caught on.     I loved that idea and what a perfect set to conquer several constellations in a short episode. So we've talked about the Summer Triangle in the past, and most newcomers should get familiar with that asterism, but these little constellations form a line running perpendicular to the Milky-Way as they cut through the bottom quadrant of the Summer Triangle.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

As evening twilight fades into night, look for three bright stars high in the east that form a giant triangle in the sky. Each belongs to its own constellation, but the triangle is a great way to “star hop” to areas of interest.

A triangle of three bright stars has been noted throughout human history.

The Sun is a fairly big, middle-aged star. And as sometimes happens in those middle years, it moves a little more slowly than it did when it was younger — it takes almost a month to complete one full turn on its axis. Many other stars spin much faster than the Sun does. An example is Altair, the brightest star of the constellation Aquila, the eagle. Altair is almost twice as wide and heavy as the Sun. Despite its bulk, it makes a complete turn in only about 10 hours. At that rate, a point at its equator moves at about 150 miles per second — fast enough to cross from New York to Los Angeles in less than half a minute. One reason Altair spins so fast is that it's much younger than the Sun. The Sun probably turned much faster when it was younger, too. But its magnetic field acts as a brake, slowing it down. One of the effects of Altair's high-speed rotation is that its gas is forced outward at the equator, making the star look a bit like a flattened beachball. It's about 14 percent wider through the equator than through the poles. There's a limit to how flattened the star can get, though; if Altair twirled about half again as fast as it does now, it would fly apart. Altair is low in the east as darkness falls. It forms the southern point of the Summer Triangle. The highest and brightest point is the star Vega, with Deneb forming the triangle's left point. The triangle is high in the west at first light.  Script by Damond Benningfield Support McDonald Observatory

Aquila, the eagle, spreads its wings across the evening sky as we head into summer. Right now, it's low in the east a couple of hours after sunset. Its brightest star, Altair, is at the bottom right point of the wide-spread Summer Triangle. Altair represents the eagle's breast, with its wings above and below. A pair of stars at one of the wingtips faces a spectacular future. The two stars will ram together, then explode as a supernova — in about 700 million years. The system is known as Henize 2-428. It consists of two white dwarfs — the dead cores of once-normal stars like the Sun. They're only a few hundred thousand miles apart — so close that they orbit each other once every four hours. As they orbit, though, they radiate gravitational waves — a process that causes them to spiral closer and closer. Each of the stars is a bit less massive than the Sun. So when they merge, they'll be almost twice as massive as the Sun. And for a white dwarf, that's a bad thing. With that much mass, the white dwarf can't hold itself together. It undergoes a runaway nuclear reaction that blows the star to bits. Such an explosion is known as a supernova, and it's extremely bright. For a few hours, the explosion may shine as brightly as the rest of the stars in the galaxy combined. The exploded stars will leave behind an expanding cloud of debris that will glow for thousands of years — the last hurrah of a pair of doomed stars.  Script by Damond Benningfield   Support McDonald Observatory

In this week's episode, Rachel is joined once again by Galactic Historian and Starseed Intuitive Debbie Solaris. Debbie shares her interpretation of what Starseeds are and why they are here on Earth. She notes the influx of Starseeds we are currently seeing here on our planet.Debbie offers insight into what the mission of these Starseeds is and how it connects to Indigo, Crystal, and Rainbow children. The guides us through a fascinating explanation of the galactic history that she is familiar with.She then goes into great detail about a few of the more popular races of Starseeds. Those are Lyrans, Sirians, and Plaedians. She shares the interest of each race as well as what mantra they are attuned to. Take a listen and if you'd like to get to know Debbie more you can connect with her through the following:Get on the waitlist by emailing Ann (Debbie's assistant) here:  debbie@debbiesolaris.comYouTube: Debbie SolarisWebsite: https://www.debbiesolaris.com/Instagram: @debbiesolarisFacebook: Debbie SolarisRecommended Books and Movies“Three Waves of Volunteer And The New Earth” by Delores Cannon“Destiny of Souls” by Michael Newton“Journey of Souls” by Michael Newton“The Prism of Lyra” by Keith Priest and Lyssa Royal“Valerian And The City of A Thousand Planets”Rachel would love to hear what you enjoyed most about this conversation.

This week let's give Spring a true Welcoming, as we talk about The Stars of Spring - The Spring Triangle, in particular. You may not know The Spring Triangle because it's less attention-grabbing than the Winter Circle and the Summer Triangle. But it becomes visible as early as February, and by early April, it's stars are all up by mid-evening. So, when you see the Spring Triangle is a harbinger for the warm springtime air. The Spring Triangle is made up of three of the sky's brightest stars: Regulus, Arcturus and Spica. We'll talk about each of these stars in detail. And we'll join John Reade as he shows us how to learn about the Spring Constellations! Be well. Do good. Enjoy the show!
