From the 20th of January it's going back to the Ole
#KuKluxClan (White) House !

Who thought it would come to this second Term ?
#YMCA will play for #Trump exclusively, pretending, their Song was never ment gay - what "relieving" #News for the #World. At least the most cringe Comment, whatsoever. Maybe the gay #Community should look for another Hymn, after this Comment from #VictorWillis.He made sich #Statements already before.

Wowzer! Map of cosmic flows, by yours truly, makes it to the cover of the Nature Astronomy journal.

"Galaxies from
wherever flock
together"

I'm no poet, but could this be a Haiku?

A cover of the Nature Astronomy journal, dated December 2024, Volume 8, issue number 12, featuring a three-dimensional visualization of the cosmic velocity field inferred from the Cosmicflows-4 catalog of galaxies' distances and velocities. This map spans two billion lightyears from top to bottom. The velocity field is mapped by means of tens of thousands of very thin streamlines, seeded at the positions of the catalog's galaxies. Streamlines are shown white and semi-transparent, against a black background. They exhibit a very complex pattern with multiple attractors, seen as points of convergence of the lines. A text reads Galaxies from wherever flock together.

An asteroid’sdestruction may have given Mars rings, then moons

Scientists simulated a situation that may offer an improved explanation for how the Red Planet ended up with small Phobos and tiny Deimos.
