SpaceTime with Stuart Gary - Series 29 Episode 28In this episode of SpaceTime, we dive into the groundbreaking mapping of Uranus's upper atmosphere, the European Space Agency's innovative Planetary Defense Fly Eye Telescope, and NASA's critical findings on Boeing's Starliner spacecraft.Mapping Uranus's Upper AtmosphereA new study has successfully created a three-dimensional map of Uranus's upper atmosphere, revealing how the ice giant's unusual magnetic field influences its auroral activity. This detailed mapping, reported in Geophysical Research Letters, shows emissions from molecules located up to 5,000 kilometers above the cloud tops, confirming a cooling trend over the past 30 years. The research highlights the complex dynamics of Uranus's magnetosphere, which is tilted and offset, leading to unique auroral patterns unlike any other planet in our solar system.ESA's Fly Eye Telescope for Planetary DefenseThe European Space Agency is developing the Fly Eye Telescope, designed to detect Near Earth Objects (NEOs) that could pose a threat to Earth. Inspired by the compound eye of insects, this innovative telescope uses a unique design to scan vast areas of the sky efficiently, identifying potential impact risks. With plans for a network of these telescopes, ESA aims to enhance our capability to monitor and mitigate the dangers posed by asteroids and comets.Nasa's Scathing Robert on Boeing's StarlinerNASA has released a critical report detailing the failures of Boeing's CST-100 Starliner spacecraft, highlighting engineering vulnerabilities and internal mistakes that jeopardized crew safety. The investigation found Starliner less reliable for crew survival compared to other manned spacecraft, leading to a recommendation that no further crewed flights occur until all technical issues are resolved. The report underscores the need for stringent oversight in space missions to ensure astronaut safety.www.spacetimewithstuartgary.com✍️ Episode ReferencesGeophysical Research LettersSupport our podcast: Become a supporter.

In 1892 the world's largest telescope, the Lick Observatory's 36 inch refracting telescope made the news when E.E. Barnard discovered, Amalthea, the 5th moon of Jupiter. In 2025 this historic telescope made the news again when on Christmas morning winds of 114 mph blew off a 3 ton piece of the shutter on its dome.The adaptive optics research pioneered at Lick Observatory helped in the creation of the twin giant 10 meter telescopes that sit atop Mauna Kea in Hawaii.

Astronomy Daily — S05E55 | 6 March 2026 Six stories today covering planetary defence, a cosmic laser record, a solar superstorm on Mars, space debris pollution, a mystery satellite launch, and the most charming farming experiment you'll hear about all year.   Stories This Episode 1. Asteroid 2024 YR4 — Moon Impact Officially Ruled Out NASA has confirmed, using the James Webb Space Telescope, that infamous asteroid 2024 YR4 will not hit the Moon in 2032. The space rock — once the most dangerous asteroid identified in two decades — will instead pass the Moon at a distance of around 13,200 miles. It previously held a 4% lunar impact probability, now fully eliminated thanks to Webb's extraordinary sensitivity pushing it to the limits of what the telescope can observe.   2. MeerKAT Detects Cosmic 'Gigalaser' 8 Billion Light-Years Away South Africa's MeerKAT radio telescope has spotted the most distant hydroxyl megamaser ever detected — a natural 'space laser' in a galaxy undergoing a violent collision more than 8 billion light-years away. The signal is so powerful it qualifies as a gigamaser. Adding to the serendipity, the signal was further amplified by a foreground galaxy acting as a gravitational lens on its 8-billion-year journey to Earth. The discovery points toward the future capability of the Square Kilometre Array (SKA).   3. ESA's Mars Orbiters Record Solar Superstorm Hitting Mars A new Nature Communications study reveals what happened when the record-breaking May 2024 solar superstorm hit Mars. ESA's Mars Express and ExoMars Trace Gas Orbiter recorded unprecedented electron density spikes in the Martian upper atmosphere — up to 278% above normal — and both spacecraft experienced computer glitches from the energetic particles. The study uses a novel spacecraft-to-spacecraft radio occultation technique and highlights how Mars's lack of a global magnetic field leaves it vulnerable to solar events in ways that Earth is not.   4. SpaceX Falcon 9 Re-entry Directly Linked to Atmospheric Lithium Plume For the first time, scientists have directly tied a specific rocket re-entry to a measurable atmospheric pollution event. Researchers at the Leibniz Institute for Atmospheric Physics detected a tenfold spike in lithium vapour in the upper atmosphere — from 3 to 31 atoms per cubic centimetre — in the hours following the uncontrolled re-entry of a Falcon 9 upper stage off Ireland in February 2025. Eight thousand backward atmospheric simulations confirmed the connection. Published in Communications Earth & Environment, the paper raises important questions about the growing chemical footprint of the commercial space industry.   5. Rocket Lab Launches Mystery Satellite — 'Insight at Speed is a Friend Indeed' Rocket Lab completed its 83rd Electron launch from New Zealand, deploying a single satellite for a confidential commercial customer to an orbit 470 km above Earth. The company announced the mission just hours before liftoff, offering no further details on the customer or the payload's purpose.   6. Scientists Grow Chickpeas in Simulated Moon Dirt for First Time Researchers at the University of Texas at Austin and Texas A&M University have successfully grown and harvested chickpeas in simulated lunar regolith — the first time this has ever been achieved. Using a combination of vermicompost (worm castings) and arbuscular mycorrhizal fungi to condition the otherwise toxic, sterile moon dirt, the team produced flowering, seed-bearing plants in soil mixtures of up to 75% regolith simulant. The chickpeas have not yet been cleared for eating pending metal accumulation testing — but the team's goal of 'moon hummus' is, apparently, very much alive.   Find Us:  astronomydaily.io  |  @AstroDailyPod on all platforms Subscribe & Review:  Apple Podcasts · Spotify · YouTube · everywhere you listenBecome a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-space-news-updates--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.

Without additional data, the true nature of the rapidly northward moving point of light my Catalina Sky Survey teammate Carson Fuls had just discovered would have remained a mystery. Fortunately, this new object was tracked by telescopes in both Arizona and New Mexico. These data were used to calculate it's orbit around the Sun, estimate it's size, and give it the name 2017 UX5. When Carson first spotted this enormous 1,200 foot diameter space rock it was more than 30 million miles away traveling in our direction at 10.7 mi/s. It's orbit and that of the Earth's nearly intersect and at the closest point they are about two and one half times the Moon's distance from us apart. An asteroid the size of 2017 UX5 impacts the Earth every 76,000 years or so. According to the impact calculator developed at Purdue University and the Imperial College of London if 2017 UK5 is made of porous rock and came in at an angle of 45 degrees, it would start to break into pieces at an altitude of 41 miles and upon reaching the surface would create a crater 2.2 miles in diameter and 5/8 of a mile deep in sedimentary rock. The results 20 miles away from impact would be that of a 6.4 Richter Scale magnitude Earth quake followed by 176 mph air wind blast which would blow down 90% of the trees and collapse wood frame buildings. Fortunately asteroid hunters have not discovered any object like Carson's discovery with our number on it.

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 & August 2025. Today's 2 topics: - After the Earth the Sun is the most important object for human beings in the Universe.  It is the energy source which produces our food and is the source for all of the energy and motion around us except for geothermal and nuclear energy sources. The Sun is normally well behaved the exception being solar storms which can dump incredible amounts of energy onto the Earth. Scientists are working hard to understand solar super storms to enable humans to mitigate the trillions of dollars damage one could cause to our modern electronic technology.   - The US National Science Foundation's Daniel K. Inouye Solar Telescope is the worlds largest solar telescope. It is perched 10,000 feet  above sea level on the top of Haleakalā on the Hawaiian island Maui.   Its location and 4 meter mirror enables the Inouye to see details in the solar atmosphere as small in diameter as the island of Manhattan. 3D maps of the solar atmosphere produced by the Inouye's new Visible Tunable Filter will enable humans to put their equipment into a safe mode when necessary.   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!

Send a textMost people have looked to the skies and wondered if the universe has a boundary, or maybe it goes on for ever. The universe might be finite, with and end somewhere. Or, it might be infinite, with an infinite amount of space and matter. Both of thos throw up some mind bending questions, and maybe even real life duplicates of ourselves. Problem is, we would never be able to observe them, or even test for their presence, or even know if they exist.

On Earth living things are everywhere from the deepest ocean depths to the highest mountain tops. On our home planet RNA (Ribonucleic Acid) is a complex essential molecule involved in the process of translating genetic information into the working components of living cells. In a recent paper in the peer reviewed scientific journal Proceedings of the National Academy of Sciences , Dr. Yuta Hirakawa and his team of two coauthors report on their experiments to produce RNA under conditions similar to those which may have occurred in the early history of Earth and Mars.

How do you establish a telescope? For Caltech astrophysicist Professor Jonas Zmuidzinas, the answer involves time, money, and incredibly sensitive detectors that can pick up everything from water in the dusty discs around young stars to galaxies in the far reaches of the Universe.

This galaxy is believed to be composed of about 99% dark matter, making it one of the most dark matter-dominated galaxies ever detected. The findings, published in Astrophysical Research Letters, reveal that dark matter constitutes roughly 80% of the universe's total matter, and CDG2's faint presence was confirmed through observations of its globular clusters using NASA's Hubble Space Telescope and the European Space Agency's Euclid Space Observatory.Artemis 2 Mission Delayed AgainNASA has announced another delay for the Artemis 2 mission, which aims to return humans to lunar orbit for the first time in over 50 years. A helium leak discovered in the Space Launch System (SLS) rocket's upper stage has prompted the agency to roll back the launch vehicle to the vehicle assembly building for repairs. This setback eliminates the potential for a March launch, with the next available windows opening in early April. The Artemis 2 mission will carry a crew of four on a 10-day journey to the Moon, including critical system tests and satellite deployments.Australia's Hypersonic Scramjet Launch ImminentAn Australian company is set to test its new hypersonic scramjet-powered aircraft, the Dart AE, before the end of the month. This innovative vehicle will utilize a 3D printed Spartan Scramjet engine, designed to operate at speeds exceeding Mach 5 with liquid hydrogen fuel. The mission, codenamed Cassowary Vex, will launch aboard a Rocket Lab electron rocket and aims to validate the scramjet propulsion system under real hypersonic flight conditions while producing zero carbon emissions.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Research LettersBecome a supporter of this podcast:  https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support.

To get an idea of the energy involved in a rocket launch, the NASA Saturn V, moon rocket, fully fueled on the launch pad contained the chemical energy of 2,000 pounds of TNT. This old technology could carry us to Mars and back on missions that would last years. To cut the mission time, the risks, and the mass of supplies required for such a prolonged space mission NASA is looking at alternative means of rocket propulsion. Back in the 1950s NASA's project Orion was a study to investigate propelling a rocket by a series of atomic bomb explosions behind the vehicle. Now a safer and more gentle way of propelling a space craft with nuclear fission is being studied as the result of a NASA grant to BWX Technologies. The concept is to heat liquid hydrogen using a high temperature fission reactor furnace which would expel the gas at a high velocity producing the rocket's thrust. The process would be about twice as efficient in terms of thrust per pound of fuel when compared to burning a hydrogen and oxygen mixture. Since it is unacceptable to release trace amounts of radioactivity in the rocket's exhaust, engineers are investigating a technique developed by NASA in which the hydrogen exhaust is burned with oxygen to produce water which can be caught and decontaminated. Don't expect to buy a round trip ticket on a high speed fission powered rocket any time soon. However, in the long run nuclear technology could revolutionize the exploration and colonization of our solar system.

In April 2029 on one of the luckiest Friday the 13th in human history the 1500 ft by 500 ft asteroid Apophis will pass within 23,600 miles of the Earth's surface traveling at some 4.6 mi/s. This is extremely fortunate since an Apophis impact would release the energy of scores of nuclear weapons and cause wide spread devastation. NASA's OSIRIS-APEX will become the companion of the potentially hazardous asteroid Apophis on 5 June 2029,

You're highly capable. So why does your next move feel so unclear? For senior leaders at a career inflection point — whether navigating a layoff, a values misalignment, or a long-overdue pivot — the problem is rarely a lack of skill. It's a lack of perspective. In this episode, executive coach and strategic advisor Karen Kunkel Young joins host Lori Adams-Brown to talk about what high-performing leaders consistently miss when they're standing at a crossroads — and what it actually takes to move forward with clarity, agency, and intention.

Eighteen hours before my Catalina Sky Survey teammate Rose Matheny first spotted a small space rock with our Schmidt telescope on Mt. Bigelow, Arizona it had passed less than the Earth's diameter from the surface of our planet. Rose was able to discover this Smart Car sized space rock after it moved out of the Sun's glare. At this point it was about the Moon's distance from her and was traveling away at 3.4 mi/s. After Rose posted her discovery observations on the Minor Planet Center's Near Earth Object Confirmation page, for the next 24 hours it was tracked by telescopes in Spain, Illinois, and Arizona. Scientists at the Minor Planet Center used these data to calculate it's orbit around the Sun, estimate it's size and give it the name 2017 UJ2. This small asteroid had come near the Earth in 1978 but was invisible to the technology which astronomers had available at the time. 2017 UJ2 will not come close enough for us to detect in the foreseeable future, however, there are likely to be tens of millions of others like it which can come close to Earth. A small asteroid the size of Rose's discovery is likely to enter our atmosphere at least once a year and explodes at about 4 times higher than airliners fly. If such an event happened at night and you were lucky enough to see it you would be treated to a fantastic light show. If you are as lucky as a power ball winner you might even be able to find a piece of it on the ground.

Bob Zimmerman covers ESA's fast-tracked Apophis asteroid mission, a commercial attempt to rescue a NASAtelescope, and the contrasting regulatory environments of the UK and New Zealand for space launches.

The Earth's atmosphere does a good job of protecting humanity from space weather, however, occasionally a major event does break through our shield and gets our attention. Tree rings and ice cores have recorded past space weather events thousands of time larger than which have occurred in the modern age. investing in research seems wise.

In an area which is about 1/400th of the entire sky, the NASA Kepler spacecraft has discovered 30 Earth like planets which are likely to have liquid water on their surfaces orbiting distant stars. These planets are likely to represent a tiny sample of the habitable planets which exist in the Milky Way. In spite of our efforts to find them, the question remains where are the alien civilizations? In a recent talk given at the Division of Planetary Sciences meeting Dr. Alan Stern of the Southwest Research Institute suggests that perhaps the majority of worlds with biology and intelligent civilizations exist on interior water ocean worlds where their existence is hidden by the thick layers of rock and ice which separate them from the hostile vacuum of space. We know that in our solar system alone the moon of Jupiter Europa, Saturn's moon Enceladus, and perhaps several other small worlds are likely to have oceans of nutrient rich liquid water covered by a thick layer of rock and ice. We also know that Whales and Dolphins have larger brains than humans, communicate with each other, and exhibit other forms of intelligence. Advanced civilizations existing in ice covered seas may know little of the greater Universe, may find it difficult to consider transporting enough water to travel beyond their worlds, and may not think that it is possible to communicate with others of their kind who are similarly hidden under miles and miles of radiation absorbing ice and rock.

Around the world those who value the natural night sky are evaluating the effects of light pollution. In addition to impairing astronomy and star gazing the past 100 years of increasing light pollution is proving to be harmful to human health and the natural world upon which we all depend. The purpose of the Dark Sky Network is monitor and facilitate the mitigation of the harmful effects of light pollution.

A nontechnical talk by Dr. Robert Kirshner, Jan 28, 2026.One hundred years ago, Edwin Hubble showed that the universe is expanding. In the 1990s, astronomers found that the expansion is not slowing down, as expected, but speeding up. This led to a Nobel Prize in Physics (for our speaker's students) and a consensus that we live in a universe that is made up of invisible dark matter, mysterious dark energy, and only a pinch of the atoms we, and everything we can see in the Universe, are made of. Dr. Kirshner explains this history in everyday language and reviews recent observations indicate that even this picture may be too simple to account for all the evidence. He also discusses the status of building the largest telescopes ever planned in Earth's Northern and Southern hemispheres. Robert Kirshner is Emeritus Professor of astronomy at Harvard and Research Professor at the California Institute of Technology. He was the Head of Science at the Gordon and Betty Moore Foundation, and now serves as the Executive Director of the Thirty-Meter Telescope International Observatory.  

On it's gravitational leash, Earth's pet space rock, 2016 HO3, accompanies us at a distance of between 38 and 100 times the Moon's distance from Earth as we both travel about the Sun. As this tiny asteroid orbits the Sun it spends about half of it's time inside the Earth's orbit where it moves faster and passes ahead of us and the other half of it's yearly path outside of our orbit which causes it to lag behind our home planet. Since it's discovery little has been known about Earth's pet space rock leaving some to speculate that perhaps it is an old rocket booster or other piece of space junk. To answer this question, Dr. Vishnu Reddy of the University of Arizona's Lunar and Planetary Laboratory headed up a team of astronomers who used the University of Arizona's Large Binocular Telescope and the Discovery Channel's Telescope to determine some of it's properties. This team of researchers found that 2016 HO3 is indeed a natural object about 100 to 300 feet in diameter, rotates about once every 28 minutes, and is made of material similar to meteorites which have landed on Earth. Our pet space rock, 2016 HO3, has apparently been in it's present relationship to Earth for a hundred years and is likely to remain so for hundreds of years to come. Even though 2016 HO3 is not gravitationally bound to the Earth, the combination of the Sun's and Earth's gravitational pulls keeps it relatively near making it easy to reach and thus is an ideal candidate for visits by human or robotic spacecraft.

However, new research published in the Astrophysical Journal Letters indicates that it may have experienced dramatic flares in the past. Observations from the CRISM Space Telescope reveal X-ray emissions from a gas cloud near Sagittarius A, suggesting a history of explosive activity that alters our understanding of supermassive black hole evolution and the history of our galaxy.Water Origins of Jupiter's Galilean MoonsA groundbreaking study has determined that the contrasting water content of Jupiter's four large Galilean moons was established during their formation rather than evolving later. This research sheds light on the stark differences between Io, which is dry and volcanically active, and Europa, believed to have a subsurface ocean. The findings suggest that the primordial environment around Jupiter played a crucial role in shaping these moons' compositions.Meteor Impacts Trigger Dust Avalanches on MarsNew evidence indicates that meteor impacts on Mars are causing dust avalanches, creating dark streaks on the planet's surface. An analysis of images from the European Space Agency's ExoMars Trace Gas Orbiter reveals that these avalanches occur primarily due to dry processes, driven by seasonal dust and wind activity, rather than water-related phenomena. This discovery enhances our understanding of Martian surface dynamics and the impact of meteor activity.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journal LettersNature CommunicationsBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.(00:00:00) Sagittarius A's hidden violent past revealed(00:12:45) Origins of water on Jupiter's Galilean moons(00:25:30) Meteor impacts causing dust avalanches on Mars(00:35:00) February night sky highlights and celestial events.(00:00:00) This is space time series 29, episode 13 for broadcast on 30 January 2026(00:00:47) X ray emissions from the Crism Space Telescope suggest Sagittarius A flared(00:07:59) A new study claims dust avalanches caused by meteor impacts are creating Martian streaks(00:10:22) February is the second month of the year in the Julian and Gregorian calendars(00:12:03) February's Orion meteor showers usually peak around February 8th(00:22:18) Blue supergiant Rigel is the second brightest star in the constellation Orion(00:31:08) Rygel: Sirius is the brightest star in the night sky(00:35:09) February is a great time to look for bright stars in the night sky(00:38:04) The night sky is sparse with the old planets at the moment

On Earth, human life is enabled by plants which provide us with calories, vitamins, fuel, medicines, and oxygen to breathe. In addition, recent scientific studies indicate that plant cultivation reduces anxiety and depression and has a positive influence on diabetes, heart disease, obesity, and longevity. Perhaps this is the reason that 80% of the cultivated plant species on planet Earth are not used for any food related purpose. On long duration space missions astronauts live in close quarters isolated from the natural world where the basic activities like eating, sleeping, and attending to bodily functions are difficult and stress producing. Recent research conducted on the International Space Station suggests that space gardening helps astronauts to cope with the sterile space craft interior, allows them to combat boredom, as well as some of the other negative psychological effects of their long period of confinement. Specific examples of International Space Station gardens include astronaut Scott Kelly's first zinnia to bloom in space and astronaut Peggy Whitson's small crop of space soybeans. For many thousands of years people making long journeys have taken plants for food and recreation with them. It is likely that when humans travel to Mars they will continue this practice. The plants that Mars explorers take with them will provide a source of fresh fruits and vegetables , fresh air to breathe, and perhaps a psychological benefit that is crucial to the success of their mission.

In the distant past things in our solar system were very much more wild and violent than they are today. 4.5 billion years ago a Mars sized object called Theia impacted Earth producing our Moon. Scientists are able research this event using the current chemical compositions of the Earth and Moon.

SpaceTime with Stuart Gary Gary - Series 29 Episode 9In this episode of SpaceTime, we unravel the enigma of the universe's mysterious little red dots, delve into groundbreaking insights from Jupiter regarding the evolution of our solar system's planets, and mark the commencement of construction on Earth's largest gamma-ray observatory.The Mystery of the Little Red DotsA fascinating new study reveals that the enigmatic little red dots observed in early images from the NASA Webb Space Telescope are, in fact, young black holes cloaked in ionized gas. Researchers from the Niels Bohr Institute's Cosmic Dawn Center have determined that these black holes, much smaller than previously thought, are in the process of consuming gas, which creates immense heat and radiation, giving them their distinctive red appearance. This discovery sheds light on the formation of some of the universe's earliest black holes just 700 million years after the Big Bang.Jupiter's Role in Planetary EvolutionNew simulations indicate that Jupiter may contain up to 50% more oxygen than the Sun, providing fresh insights into how the planets in our solar system formed. By developing a comprehensive model of Jupiter's atmosphere, researchers have resolved a long-standing debate regarding the gas giant's chemical composition. The findings suggest that Jupiter's atmosphere circulates much more slowly than previously believed, which could alter our understanding of planetary migration and formation processes.Construction of Earth's Largest Gamma-Ray ObservatoryEngineers have officially begun construction on the Cherenkov Telescope Array Observatory, set to be the largest gamma-ray telescope ever built. Located in Chile's Atacama Desert, this observatory will significantly enhance our ability to study high-energy cosmic phenomena, such as black holes and supernovae. With over 60 telescopes across two sites, the observatory will allow astronomers to observe gamma rays with unprecedented accuracy, potentially unlocking new discoveries about dark matter and the fundamental laws of physics.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature JournalPlanetary Science JournalAdvances in Atmospheric SciencesBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.(00:00:00) New study reveals little red dots in Webb images are young black holes(00:07:30) Jupiter may have 50% more oxygen than the Sun, reshaping planetary formation theories(00:15:45) Construction begins on the Cherenkov Telescope Array Observatory(00:22:00) New data confirms 2025 saw record ocean heat storage(00:25:30) Advances in autonomous driving technology showcased at CES 2026.

In less than 24 hours, while observing with the Catalina Sky Survey's 60 inch telescope on Mt. Lemmon, Arizona , I discovered two 25 foot diameter space rocks that theoretically can pass less than a quarter of the Moon's distance from us. After I posted my discovery observations on the Minor Planet Center's Near Earth Object Confirmation page one of them received immediate attention, as an incoming object, and was tracked by observers at 14 different observatories around the world. Scientists at the Minor Planet Center used these data to calculate it's 926 day orbital path around the Sun, estimate it's size, and give it the name 2017 TH5. 36 hours after I first spotted 2017 TH5 streaking through the night sky it came to less than 60,000 miles from the surface of our planet traveling at 7.6 miles per second. 8 hours and 49 minutes later it passed less than half a lunar distance from the surface of our moon. If 2017 TH5 would have been on an impact trajectory with Earth humans would have had time to prepare for a spectacular light show. Approximately once every 5 years a tiny asteroid like 2017 TH5 enters our atmosphere exploding at an altitude about 3 times higher than airliners fly releasing the energy of about 5,000 tons of TNT. Asteroid hunters are well on our way towards being able to issue a warning to stay away from doors and windows should a small space rock be discovered to be on an impact trajectory with planet Earth.

Mapping the Future of Space Observation. Guest: DINESH NANDAL. Advancing cosmology requires a "James Webb 2.0" with larger mirrors and a successor to the Chandra X-ray telescope. Funding is also needed for researchers to develop new mathematical models.
