SpaceX is preparing to launch its next batch of Starlink satellites from Florida’s Space Coast in the predawn hours of Thursday morning.
"There's one we haven't found — a planet just like ours. At least, not yet."
Artemis 2 astronauts will be the subjects of nearly as many experiments as they'll be performing during their trip around the moon.
SpaceX has moved its newest Starship spacecraft to the launch pad for testing ahead of the megarocket's upcoming 11th test flight.
Alien objects may be seeding the universe. Here's what that means.
In a recent discovery, the James Webb Space Telescope (JWST) detected a massive stellar eruption measuring eight light-years across. This outflow, known as Sharpless 2-284 (Sh2-284 for short), is located about 15,000 light-years away in the outer reaches of the Milky Way. Based on an analysis by an international team of astronomers, this outflow appears to be coming from a newly forming star (a proto-star). It is moving at relativistic speeds (hundreds of thousands of kilometers per hour), and its size and strength indicate it is a rare phenomenon.
Saturn makes its triumphant return to the dusk sky.
You know, if you take away the lack of air and water, the weaker Sun, the lower gravity, and the toxic soil, Mars isn’t all that bad of a place to live. And there are certainly worse places to live, like, I don’t know, Ohio (I’m allowed to say that because I grew up there). But there’s been a big push in the past two decades to not just go to Mars and visit, like we did with the Moon fifty years ago, but to stay there. Put down roots. Establish ourselves. Build a colony or a settlement.
78 million years ago, a 1.6 km asteroid slammed into what is now Finland, creating a crater 23 km (14 mi) wide and 750 km deep. The catastrophic impact created a fractured hydrothermal system in the shattered bedrock under the crater. There's evidence from other impact structures that in the aftermath of a collision, life colonized the shattered rock and heated water that flowed through it. But determining when the colonization happened is challenging.
A new study suggests that a group of cells, key for the health of blood and the immune system, are vulnerable to aging-like processes after spending time on the ISS.
"It's been fantastic to watch 'Foundation' become such a global phenomenon, with fans tuning in from every corner of the world."
The moon is near new phase this week, and clearer skies and cooler overnight temperatures means that this is also an optimum week to check out the beautiful summer Milky Way.
Watch live as a potentially hazardous asteroid makes a close flyby of Earth on Sept. 18.
Titan joins its shadow for a "grand finale" this October.

Climate models are complex, just like the world they mirror.
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed an unexpected difference between the powerful winds launching from a disc around a neutron star and those from material circling supermassive black holes. The surprisingly dense wind blowing from the stellar system challenges our understanding of how such winds form and drive change in their surroundings.
NASA plans to send the ISS into Earth's atmosphere in 2030, and it has no plans for a replacement — at least, not directly.
The turning point seems to have been after 2008, which had the lowest amount of solar activity on record.
The Mokoqi star projector is aimed at babies and young children and is designed to aid sleep with ambient projections but is not scientifically accurate.
Astronomy isn’t just about distant stars; it’s also about the human effort here on Earth that makes it possible to extend our vision out into the cosmos.
