ESO 510-13: Warped Hubble Heritage Team (STScI/AURA), C. Conselice (U. Wisconsin/STScI) et al., NASA Hubble Catches a Warped Spiral Galaxy in Profile -- Popular Science
The Hubble Heritage Team captured the warped structure of spiral galaxy ESO 510-13 so beautifully in this pretty space pic. Behold, the product of galactic collisions.
At least, that’s one theory. Most spiral galaxies are flat disks made up of millions of stars and gas and planets and whatnot orbiting a galactic center (which is thought to be, at least in the case of large galaxies, a supermassive black hole). These disks are thought to flatten out the way they do by the nature of the collision of gas clouds early in a galaxy’s lifespan.
