This image captured by U.S.-Indian Earth satellite NISAR on Nov. 10, 2025, shows Washington's Mount St. Helens. The image is cropped from a much larger swath spanning the Pacific Northwest on a cloudy day; NISAR's L-band SAR instrument is able to peer through the clouds at the surface below.
More than 50 years after humans first flew around the moon, Artemis astronauts will repeat the feat on Monday and use the most basic instrument to study it: their eyes.
The early universe is absolutely so far outside our understanding of how the world works it's hard to describe in words. Back then, the cosmos wasn't filled with stars and galaxies but with a boiling soup of quarks and gluons, with a few microscopic black holes thrown in, occasionally detonating like depth charges. That's the early universe theorized by a new paper, available in pre-print from arXiv, from researchers at Vrije Universiteit Brussel and MIT anyway.
The Artemis astronauts have taken in sights of the moon never before seen by human eyes, crew members reported on Sunday as their spacecraft crossed the two-thirds mark on their journey to a long-anticipated lunar flyby.
Now more than halfway to the moon, the Artemis II astronauts prepared for their historic lunar fly-around to push deeper into space than even the Apollo astronauts.
