A beautiful image on #APOD today shows two #galaxies colliding with each other, and the debris that is left behind. As explained in the description on their website:
https://apod.nasa.gov/apod/ap240220.html
the sparkly bits ✨ are the new stars that formed during the collision.
The distorted shape of this system reminds me of the giant 'cosmic question mark' discovered by JWST last summer. Same process has happening there, too: two galaxies colliding, one of them showing more heavily distorted than the other.

I put these two images side by side. The new image is a nice confirmation of the hypothesis put forward in the case of the cosmic question mark, and more generally, it shows that astronomers understand what happens when galaxies interact with each other.
