In the final days of his six-month stint aboard the International Space Station (ISS), Danish astronaut Andreas Mogensen took some time out of his science work to snap some striking photos of a snow-covered Grand Canyon.
The images were captured from the station in recent days as it orbited Earth at an altitude of around 250 miles.
Astronomers have spotted a gargantuan protocluster – the primordial beginnings of a galaxy cluster – by searching near a quasar in the early universe.

A protoplanetary disk is a disk of dense gas and dust, orbiting a newly formed star. It is assumed that planets are born by the gradual accumulation of material in such a structure, therefore discoveries and studies of protoplanetary disks are essential for improving our understanding of planetary formation processes.
Now, a team of astronomers led by Ciprian T. Berghea of the U.S. Naval Observatory (USNO) in Washington, DC, has discovered a new disk of this type that is associated with an infrared source known as IRAS 23077+6707. The finding was made by inspecting the Pan-STARRS data while working on a variability study of active galactic nuclei (AGN) candidates.
The more we learn about Earth’s past, the wilder it gets.
Known as the Radcliffe Wave, astronomers have discovered that this chain of stars, gas, and dust is propagating like a wave, too.
Could we disregard author rights for the sake of putting civ backup?
And put a lot more or at least more chosen pieces (but what to choose)?
We are thrilled to announce that on February 22, 2024, our third attempt to land the Arch Mission Foundation’s 30 million page Lunar Library on the Moon has succeeded!
