Iron isotopes show that salty seawater pockets beneath the ice were as cold as −15°C.
Hunt for the names of the many moons surrounding our solar system's eight planets.
A total lunar eclipse will turn the moon blood red for billions across North America, Australia and East Asia.
As AI invades everyday life, we’ve gone back and revisited the best video games with memorable AI characters, evil or otherwise.
This month’s episode showcases the stars and planets visible on March evenings. First up: March 3rd’s predawn a total lunar eclipse! Then track down three planets after sunset, and savor the easy-to-spot Winter Triangle of bright stars.
It'll be the last blood moon until New Year's Eve 2028.

SpaceX launched a Falcon 9 rocket early Sunday from Vandenberg Space Force Base in California, carrying another batch of satellites for the company’s Starlink internet service.
In the future, farmers on the Moon and Mars will have a big challenge: how to grow healthy food in two extremely unhealthy environments. That's because the soil on both worlds isn't at all hospitable to plants and animals. Neither are other conditions. Both are irradiated worlds, Mars has a thin atmosphere and the Moon has none at all. So, how will future colonists on either world grow their food?
It's been about 8 months since the Vera Rubin Observatory (VRO) saw first light. Now the telescope is scanning the night sky to detect transient changes and sending alerts to astronomers and observatories around the world so they can perform follow-up observations. This alert system is one of the last milestones before the VRO starts its primary endeavour: the decade-long Legacy Survey of Space and Time (LSST).
On Episode 199 of This Week In Space, Rod Pyle and Tariq Malik talk with Dr. Pascal Lee, who has thoughts on how and when robots may perform better —and more safely —than humans in space.
NASA has severe penalties for those who dare to deal in astromaterials.
"I am programmed in multiple techniques. A broad variety of pleasuring."
A rare atmospheric effect called selenelion could briefly let skywatchers see the rising sun and a blood moon at the same time.
NASA's Artemis 3 mission will no longer land astronauts on the moon —and it might not involve SpaceX's Starship megarocket, either.
Imagine trying to study the foundations of an ancient city while it's still being built. The noise is deafening, the dust is everywhere, and the whole place is barely visible through the haze. That is almost exactly the challenge astronomers face when trying to understand how vast cities of hundreds of galaxies first came into being. A new discovery has just given them their best look yet.
Imagine trying to reconstruct the history of a city by studying only its oldest surviving buildings. You can't watch it being built, you can't interview the architects, all you have are the structures themselves, their materials, their arrangement, the subtle clues locked into their very fabric. That is essentially what astronomers do when they study the formation of our Galaxy, and a new study has just given them their biggest collection of clues yet.
Here's a thought experiment that keeps planetary scientists awake at night. Strip every living thing from our planet, every bacterium, every blade of grass, every creature that has ever drawn breath and ask a simple but profound question: would Earth still be a world capable of supporting life?
Earlier today, NASA announced that it would be increasing the cadence of its missions to meet its objectives under the Artemis Program. It is also making changes to its mission architecture to include a standard vehicle configuration and undertake one surface landing every year after 2027. In real terms, this means that a lunar landing will not take place as part of Artemis III in 2027, but during Artemis IV, currently scheduled for 2028. Instead, Artemis III will involve a rendezvous in Low Earth Orbit (LEO) to test the systems and operations for the first lunar landing in over sixty years.
Jupiter is the largest planet in the solar system and has proudly boasted about this since time immemorial, with its scientific confirmation occurring by Galileo Galilei in 1610. It was later found that Jupiter has a bulging equator caused by its rapid rotation, turbulent atmosphere, and complex interior mechanisms despite its massive size, and scientists have even measured its “waistline” down to a tenth of a kilometer. Now, imagine being the largest planet in the solar system and you’re told you’re not as big as you thought. Where probably most humans would be thrilled to find this out, how do you respond if you’re Jupiter?
Two Falcon 9 launches from Florida and one from California deployed 83 Starlink satellites into low Earth orbit, wrapping up February 2026 for the SpaceX network.
A new analysis of Apollo moon samples reveals insight into the history of the lunar magnetic field.
