In the midst of the COVID-19 pandemic, we're hearing an awful lot about the fraught relationship between science and media. In his book, News from Mars: Mass Media and the Forging of a New Astronomy, 1860-1910 (University of Pittsburgh Press, 2019), historian of science Joshua Nall shows us that a blurry boundary between science and journalism was a key feature—not a bug—of the emergence of modern astronomy. Focusing on objects and media, such as newspapers, encyclopedias, cigarette cards, and globes, Nall offers a history of how astronomers' cultivation of a mass public shaped their discipline as it managed controversies over the possibility of canals on Mars, and even interplanetary communication. This book is strongly recommended for historians of science and communication, as well as those with an eye for material culture. Joshua Nall is curator of modern sciences at the Whipple Museum of the History of Science in the Department of the History and Philosophy of Science at the University of Cambridge. Mikey McGovern is a PhD candidate in Princeton University's Program in the History of Science. He is writing a dissertation on how people used statistics to make claims of discrimination in 1970s America, and how the relationship between rights and num- bers became a flashpoint in political struggles over bureaucracy, race, and law.

Recently, using data from the Japanese infrared telescope AKARI,  Dr. Amos Y.A. Chen and his collaborators published a paper in the Publications of the Astronomical Society of Australia which predicts the approximate positions of two massive Planet 9 candidates. To arrive at their conclusions this team carefully searched the AKARI observations for objects which over the course of months change their positions relative to distant stars and galaxies.   Further  observations are required to determine if either of these move like a Planet 9 or if instead they are some other type of distant astronomical object.

What would happen if we moved a jovian moon to Mars? What are black holes spitting out as those jets? What's the best case scenario for Europa Clipper's search for life? And in Q&A+, how are we searching for Sun-like stars?

How did supermassive black holes get so big so early? There are two main models for that, and JWST just got a huge boost for the one that suggests they can form via a direct collapse of gas clouds. How did the researchers pull the first observations of a potential birth of a SMBH? Finding out in this interview.

Strange new worlds. Dear Cheap Astronomy – How big can rocky planets and how small can gas giants get? Well there is some data, so we don't have to talk in hypotheticals. There's a rocky planet with about 40 times Earth mass and about 3 and a half times Earth's diameter, which is about 85% of Neptune's diameter. So, it's a mighty big rocky planet that's approaching gas giant scale.   Dear Cheap Astronomy – Will we grow crops in Martian regolith? So, firstly you can't really grow any plants from Earth on Mars since Earth plants need oxygen. While photosynthesis can make oxygen, plants don't have vascular system that can move the oxygen around. So if there isn't enough oxygen in the atmosphere to start with, then the roots die and the plant dies.   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!

From October 9, 2013. Nothing lasts forever, stars live and die over the course of hundreds of millions to billions, and in the case of red dwarf stars, trillions of years. Planets are born from the remnants of their parent stars and die over a shorter timescale. Life on those planets, if it exists, is presumed to be shorter still, governed entirely by the environments provided by the combination of the star and planetary characteristics. How long life lasts there ultimately depends on how long the star lives and how it dies.   Using our solar system as an example, since we know life arose here, how long will it last?  Astronomers think they have an answer.   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!

The Trappist-1 planetary system located about 40 light years away in the constellation of Aquarius consists of a small red dwarf star and 7 Earth sized planets. By carefully studying changes in the planet's transit timings and the shape of the dip in the host star's brightness as each planet transits across it, astronomers have been able to measure the orbital period, radius, and approximate mass for each of the 7 planets. Dr Billy Quarles of the University Oklahoma and his team used thousands of numerical simulations on super computers to investigate the range in each planet's parameters which would cause it to have a stable orbit and would thus produce the Trappist-1 solar system which we see today. Their results, published in the Astrophysical Journal Letters suggests that 6 of Trappist-1's planets have rocky composition like the Earth the remaining one may be composed of 25 % water by mass compared to 0.02% water by mass for Earth. The next step will be to use the James Web Space Telescope equipped with the latest scientific instruments to study the atmospheres of these distant worlds.

Big Bear Solar Observatory is a unique facility operated by the New Jersey Institute of Technology.  Its 1.6 meter Goode Solar Telescope is located on the north side of Big Bear Lake at an elevation of 6,760 feet above sea level in the  San Bernardino Mountains of Southern California.  Being surrounded by cold water at high altitude provides the site with exceptional atmospheric stability and thus the possibility of extremely high quality solar images.  It is hard to predict the value of basic research, however, work like this will eventually enable scientists to better understand how solar flares and other activity in the Sun's atmosphere effect  astronauts, communications systems, auroras, radio blackouts, geomagnetic storms, satellites, power grids, and more on our home planet

Could we aim asteroid YR4 at the Moon on purpose? What would happen to babies born and raised on Mars? Should we use water as an insulation layer for our spacecraft? And in Q&A+, could we mine an asteroid that's stuck in a Lagrange point?

Did you know that seven near-Earth asteroids passed closer to Earth than the Moon in the last thirty days?

Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume by a small margin, but is less massive than Eris. Like other Kuiper belt objects, Pluto is made primarily of ice and rock and is much smaller than the inner planets. Pluto has roughly one-sixth the mass of the Moon and one-third its volume. Originally considered a planet, its classification was changed when astronomers adopted a new definition of planet.

Just three interstellar objects have ever been detected in our Solar System, each arriving from the depths of interstellar space. In this episode, we explore the latest: 3I/ATLAS, a newly discovered interstellar comet first spotted on July 1, 2025. Bryce Bolin, research scientist at Eureka Scientific, joins host Sarah Al-Ahmed to share what makes this object special. As one of the few astronomers who has studied all three known interstellar objects—1I/ʻOumuamua, 2I/Borisov, and now 3I/ATLAS—he offers unique insight into how these rare visitors expand our understanding of planetary systems beyond our own. We also check in with Bruce Betts, chief scientist of The Planetary Society, for a look at the upcoming ESA and JAXA’s Comet Interceptor mission, which may one day chase down a future interstellar comet.

Humans are moving towards a day when there are space colonies in orbit, on the Moon, and the planet Mars, places where the force of gravity ranges between zero and 38% of what we experience every day. What effect will such different environments have on the regeneration of liver, skin, and other human body organs? To discover how the remarkable ability of Planaria flat worms to regenerate amputated body parts functions in a weightless environment researchers at Tufts University compared a group of whole and amputated flat worms which had lived for 5 weeks on the International Space Station with control groups which remained behind on planet Earth. The space faring flatworms were found to have undergone metabolic and other body function changes which persisted after they returned to Earth. Strangely one of the amputated worm fragments sent into space developed into an extremely rare double headed worm. Researchers were astonished since they had not seen this happen once during 5 years of observations of 15,000 worms. Further when both heads were removed from the space traveling double headed worm's middle section it grew 2 heads indicating that its body modification plan was permanent. The implications of these experiments for humans in space, if any, remain to be determined. Bottom line is we just don't know enough about how human reproduction and development will work off the Earth to plan on having permanent sustainable colonies elsewhere.

For almost their entire 4.5 billion-year existence, Earth and its moon have been galactic neighbors. And the moon isn't just Earth's tiny sidekick—their relationship is more like that of siblings, and they're even cut from similar cosmic cloth.Without the moon, Earth and its inhabitants wouldn't be what they are today: The climate would be more extreme, lunar tides wouldn't have given rise to life on Earth, biological rhythms would be off-beat, and even timekeeping and religion would have evolved differently. The new book Our Moon: How Earth's Celestial Companion Transformed The Planet, Guided Evolution, And Made Us Who We Are explores how our existence is tied to the moon's.Ira Flatow and guest host Sophie Bushwick chat with journalist and author Rebecca Boyle about how the moon came to be, how it transformed life on Earth, and how our relationship with it is changing.Guest: Rebecca Boyle is a journalist and author of Our Moon: How Earth's Celestial Companion Transformed The Planet, Guided Evolution, And Made Us Who We Are.

http://www.astronomycast.com/archive/ From October 17, 2011. What can we say about Einstein? Albert! Freaking! Einstein! Lots, actually. In this show we're going to talk about the most revolutionary physicist… ever. He completely changed our understanding of time, and space, and energy, and gravity. He made predictions about the nature of the Universe that we're still testing out.   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!

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From July, 2024. Today's 2 topics: - During a recent 60 day period asteroid hunters observed 23 asteroids which came closer to us than our Moon. Six of them passed closer to the Earth's surface than 22,236 miles which is the distance to our communication satellites.   - It is hard to obtain time on the 8m Gemini South Observatory telescope on Cerro Pachon in Chile and the Large Binocular Telescope with its twin 8m mirrors on Mt. Graham, Arizona since they are among the largest telescopes in the world. My Catalina Sky Survey teammate Kacper Wierzchos wrote a scientifically competitive proposal to obtain the time to track the potentially hazardous asteroid 2016 PR38 on both of these telescopes when it was near its furthest point from our Sun and thus much too faint for the telescopes asteroid hunters routinely use.   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!

The 2020s will be a decisive decade for in-space nuclear power. So argues Dr. Bhavya Lal, whose new report reframes the conversation around a simple idea: power, not propulsion, is nuclear's most immediate and disruptive capability. Power is what enables humans to stay and build on distant locales; without an abundance of it, she warns, we will never be more than visitors. But in an era of super heavy-lift capability, does this vision still require a nuclear solution, or can we simply brute-force our future in space with cheaper alternatives?

How do astronauts get quality sleep in space? Erin Flynn-Evans, director of the Fatigue Countermeasures Laboratory at NASA Ames Research Center, joins Planetary Radio to explore how her team studies sleep, fatigue, and circadian rhythms to keep astronauts healthy and mission-ready. She shares how her team translates sleep science into actionable strategies for NASA crews, and how a chance job as a sleep technician led her on a path to spaceflight research. Later in the show, Casey Dreier, The Planetary Society’s chief of space policy, and Jack Kiraly, our director of government relations, provide a quick update on NASA’s budget and what it means for the agency’s future. Then, Bruce Betts, our chief scientist, joins us for What’s Up to explore how and why our robotic spacecraft sometimes need to power down and rest.
