Telling Time on Other Worlds 
From Earth orbit to the Moon and Mars, explore the world of human spaceflight with NASA each week on the official podcast of the Johnson Space Center in Houston, Texas. Listen to in-depth conversations with the astronauts, scientists and engineers who make it possible…more

Seeing an eclipse from Earth is awe‑inspiring—for astronauts in space, the scene was even more grand The astronauts on Artemis II’s trip to the moon in April 2026 didn’t just have an amazing journey through space. They also saw something extraordinary. They were the first humans to see a total solar eclipse from space…more

‘It was quite a light show!’ NASA astronaut spies dramatic fireball from the International Space Station “I think it must have been some piece of orbital debris or a satellite breaking up as it entered the atmosphere.” On the International Space Station, you look down to see shooting stars. NASA astronaut Chris Williams just reminded us of that mind-bending fact, sharing footage of a spectacular fireball he saw from the orbiting lab….more

Artemis 2 heat shield is a sunken treasure in the ocean The Artemis 2 heat shield looks like a sunken treasure from the Titanic in an underwater shot following splashdown. The mission’s Orion capsule splashed down off the coast of San Diego on April 10, safely returning its astronaut crew home. Now, we can see the aftermath of that landing in a striking new photograph….more

‘I’m not religious, but …’: The Artemis II space mission stirs something deep inside us It’s been some weeks since Artemis II splashed back down to earth, but the reels are still doing the rounds on social media — especially one from a post-mission press conference where Commander Reid Wiseman said ten days in space had stirred something in his soul…more

Why SETI Might Have Been Missing Alien Signals A new study by researchers at the SETI Institute suggests stellar “space weather” could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma turbulence near a transmitting planet can broaden an otherwise ultra-narrow signal, spreading its power across more frequencies and making it more difficult to detect in traditional narrowband searches…more

Straight Shot: Hubble Investigates Galaxy with Nine Rings NASA’s Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an “arrow” — a far smaller blue dwarf galaxy — shot through its heart. Astronomers using Hubble identified eight visible rings, more than previously detected by any telescope in any galaxy, and confirmed…more

Spaceflight Started 100 Years Ago in a Massachusetts Cabbage Patch Robert Goddard arrived at his aunt’s farm in Auburn, Mass., on a cold, snowy morning 100 years ago. The wide-open spaces of the farm became on March 16, 1926, a rudimentary Cape Canaveral for an event never witnessed before on Earth: the launch of a rocket that would become a trailblazer for vehicles capable of sending satellites, probes and even humans beyond our planet’s atmosphere…more

New Theory May Explain Mysterious “Little Red Dots” in the Early Universe Astronomers at the Center for Astrophysics | Harvard & Smithsonian have proposed a new explanation for some of the universe’s most puzzling early galaxies, nicknamed “little red dots.” In the study, published in The Astrophysical Journal Letters, Authors Fabio Pacucci and Abraham (Avi) Loeb suggest that these galaxies are the result of very slowly spinning dark matter halos, an extremely rare cosmic structure…more

Sugars, ‘Gum,’ Stardust Found in NASA’s Asteroid Bennu Samples The asteroid Bennu continues to provide new clues to scientists’ biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft…more

NASA’s DART Mission Changed Orbit of Asteroid Didymos Around Sun New research reveals that when NASA’s DART (Double Asteroid Redirection Test) spacecraft intentionally impacted the asteroid moonlet Dimorphos in September 2022, it didn’t just change the motion of Dimorphos around its larger companion, Didymos; the crash also shifted the orbit of both asteroids around the Sun…more

Spectacular fireball over Europe sends meteorite crashing through roof of German home A meteorite has crashed through the roof of a house in the city of Koblenz in the west of Germany after a spectacular fireball lit up the night sky above western Europe on Sunday evening, March 8. More than 2,800 sightings of the fireball have been reported to the International Meteor Organization (IMO), with dozens of video recordings having been uploaded on social media…more
