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!

But the concept never truly disappears, and for good reason. Near-Earth asteroids, numbering in the millions, contain staggering quantities of precious metals, rare earth elements, and water ice. Ironically, those same materials — iron, gold, platinum, nickel, and dozens of others — were originally delivered to Earth by asteroids during the Late Heavy Bombardment period some four billion years ago. We're essentially talking about going back to the source. The three main asteroid types — carbonaceous (C-type), silicate (S-type), and metallic (M-type) — each offer distinct resources. Beyond metals, the abundance of water ice in the solar system could relieve pressure on Earth's increasingly stressed freshwater supply and fuel deep-space missions. Philosophically, the implications are profound. Thomas More and Nietzsche both wrestled with why scarcity drives human value systems. Flood the market with space-borne metals and the entire economic architecture built on scarcity begins to crumble. Orwell saw it too — abundance erodes hierarchy. The first trillionaires born from asteroid mining might find their wealth meaningless almost immediately after making it. But the darker scenarios deserve equal attention. Redistributing consumption off-world doesn't eliminate it. Space debris, environmental degradation beyond Earth, and the very real risk of exploitative labor structures in off-world operations — echoes of colonialism and indentured servitude — are not science fiction. They're logical extensions of human patterns. The enthusiasm may ebb and flow, but asteroid mining remains an inevitable chapter in humanity's story. The real question is what kind of story we choose to write around it. ______________________ Resources   ______________________ For more podcast Stories from Space with Matthew S Williams, visit: https://itspmagazine.com/stories-from-space-podcast Hosted by Simplecast, an AdsWizz company.

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.

Could a single ancient impact have briefly transformed one of the Solar System’s darkest moons into a cryovolcanic world? When Voyager 2 flew past Uranus in 1986, it captured the only close-up images we have of Umbriel, a heavily cratered, charcoal-dark satellite long considered geologically inactive. But one feature stands out: a bright ring inside the 131-kilometer-wide Wunda crater. In this episode, Sarah Al-Ahmed speaks with Adeene Denton, NASA postdoctoral program fellow at the Southwest Research Institute, about her team’s new study published in the Journal of Geophysical Research: Planets. Using shock physics simulations, Denton and her colleagues reconstruct the impact that formed Wunda crater to determine what Umbriel’s interior must have been like at the time. Their modeling explores whether impact-induced cryovolcanism can explain the bright deposits observed on the crater floor. Then, in What’s Up, Bruce Betts, chief scientist of The Planetary Society, joins Sarah to break down one of the key mechanisms that keeps icy moons from freezing solid, tidal heating driven by orbital resonance.

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.

Today we're gonna talk about cataclysmic variable stars, which are the result of a white dwarf stealing material from a companion star. And this whole process makes supervillain Pamela happy. Gravity is the weakest force, but on the scales of stars, it is capable of great violence. In this episode, we look at the wild physics of cataclysmic variables: binary star systems where one star is a predatory compact stellar remnant, while the other is a victimized normal star.

Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From July 2025. Today's 2 topics: - Recently my Catalina Sky Survey teammate Dr. Hannes Gröller and I traveled to the Gila Cliff Dwellings National Monument to install two night sky meters which will enable this wonderful national treasure to become an international dark sky park. Surrounded by vast tracts of unoccupied public land and having an abundance of clear weather the Gila Cliff Dwellings National Monument and the Cosmic Campground International Dark Sky Sanctuary both in New Mexico are among the best places in the world to view the natural night sky. - Sadly humans seem to be in the process of creating a cosmic land fill which will blot out much of the cosmos.   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!

Astronomy Daily — Season 5, Episode 45 | February 21, 2026 "Countdown to the Moon: Artemis II Crew in Quarantine" The Artemis II crew — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch (NASA), and Mission Specialist Jeremy Hansen (CSA) — have officially entered quarantine ahead of a targeted March 6, 2026 launch. With the second Wet Dress Rehearsal completed successfully on February 19th, humanity is just two weeks away from returning to the Moon for the first time since Apollo 17 in 1972. Anna and Avery break down everything you need to know about this historic mission. Also on today's episode: •  DARK MATTER UNDER PRESSURE: A new paper in Physical Review D claims its findings represent the first step toward the end of dark matter theory as we know it — researchers have found a plethora of baryonic (ordinary) dark matter signals that challenge the standard cosmological model. •  AURORA WATCH: A large coronal hole on the Sun has rotated into a geoeffective position, with fast solar wind expected to reach Earth around February 22nd. Skywatchers at higher latitudes should keep their eyes on the skies tomorrow night. •  MARS WATER UPDATE: New research suggests water ice on Mars may be accessible far closer to the equator than previously believed — a game-changing development for future human exploration of the Red Planet. •  SERIAL KILLER BLACK HOLES: Astronomers using James Webb Space Telescope data have confirmed that active supermassive black holes don't just shut down star formation in their own galaxies — they can suppress star formation in neighbouring galaxies too. •  SPACEX NEAR MISS: SpaceX successfully landed its Falcon 9 booster in The Bahamas for only the second time ever after launching 29 Starlink satellites — but someone at SpaceX admitted they 'almost did have a really terrible day.'

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,

Astronomers just found something cool!  Typically, most Sun-like stars host planets between the size of Earth and Neptune called 'super-Earths' or 'sub-Neptunes'. These planets often orbit their stars even closer than Mercury orbits our Sun. They're mostly rocky super-Earths or they have a thick atmosphere and a rocky core and are sub-Neptunes. They're the most common types of planet found in our Galaxy. And yet, astronomers weren't sure exactly how these planets formed.  So yeah, they found something cool!    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!

Prepare to dive deep into the mysteries of the universe as they explore intriguing theories and concepts that challenge our understanding of cosmology.Episode Highlights:- Dark Matter and Dark Energy: Daryl from South Australia presents a unique theory suggesting a connection between dark matter and dark energy, likening them to opposites with gravitational effects. Andrew and Fred dissect this idea and discuss the fundamental differences between these two cosmic phenomena.- Where Was the Sun Born? Slaty Bartfast from Norway asks if we could see the Sun's birth by pointing a telescope at its historical coordinates. The hosts explain why this wouldn't yield any observable results and discuss the concept of solar siblings born in the same gas cloud.- Black Hole Temperatures: Bjorn from Gothenburg seeks clarification on the temperature of black holes and the material that spirals into them. Andrew and Fred clarify how the extreme heat of accreting material contrasts with the near-absolute zero temperature of the black hole itself.- The Expansion of Space: Peter from Falun poses a complex question about the nature of space and time in an expanding universe. The hosts unravel the intricacies of how our measurements of distance and time are affected by the universe's expansion.For more Space Nuts, including our continuously updating newsfeed and to listen to all our episodes, visit our website. Follow us on social media at SpaceNutsPod on Facebook, Instagram, and more.

https://www.youtube.com/watch?v=sVvY9HGss8E Hosted by: Fraser Cain (@frasercain) and Dr. Pamela L. Gay (@CosmoQuest) Streamed live on Feb 13, 2026. Modern astronomy has found that the Universe can surprise us. Here's one which astronomers have called Luminous Fast Blue Optical Transients. They're kinda like supernovas, they're kind of like gamma ray bursts, but they're not like them. So what are they? In the distant Universe, are blue light flashes, bright and hard to understand. These objects, uncreatively named "Luminous Fast Blue Optical Transients," are just the kind of puzzle astronomers love. In this episode, we look at their discovery and our current understanding of what they might be.
