Observed a very bright optical transient in Pisces, which wasn’t there yesterday! #astrophotography #space #astrodon

Beautiful mosaics captured two days ago by Curiosity, on her way out of the Boxwork Terrain

Back to being part of the NewAthena community science working groups: https://www.the-athena-x-ray-observatory.eu/en/athena-community

🎉 🎉 🎉
Feels good to be back (I could not be part pf the official community for a bit due to work), Athena was/is such an integral part of who I am as a scientist and where I see the future of astrophysics!

This is RCW 86 -- a supernova remnant. In 185 AD Chinese astronomers recorded evidence of the supernova with the presence of a 'guest star'!

Although the merging galaxies are pretty, what struck me most is that I seem to have caught a few much more distant clusters of galaxies! They are barely visible as collections of oblong orange smudges.

A long time ago in a galaxy far far away…

Another galaxy came crashing through the front door, causing all kids of mayhem. These are two big galaxies in the process of merging.

During that process they pass close to (or through) each other and the gravitational interactions stretch them and fling their constituent stars and gas far and wide. In this case, into long tidal tails, which are showing signs of star formation.

Everywhere you can see blue, hydrogen gas got stirred up and collapsed into giant hot blue stars.

This pair is know as the Antennae Galaxies and they sit about 70 million light years away in the constellation Corvus. So their crash is actually 70 million years more advanced than what we can see!
