Battle Beyond The Stars

at

Behold: a tumultuous cosmic conflict – a Star War, if you will – in the region of spiral galaxy UGC 1810. To wit:

The featured galaxy is labelled UGC 1810 by itself, but together with its collisional partner is known as Arp 273. The overall shape of UGC 1810 — in particular its blue outer ring — is likely a result of wild and violent gravitational interactions. This ring’s blue colour is caused by massive stars that are blue hot and have formed only in the past few million years. The inner galaxy appears older, redder, and threaded with cool filamentary dust. A few bright stars appear well in the foreground, unrelated to UGC 1810, while several galaxies are visible well in the background. Arp 273 lies about 300 million light years away toward the constellation of Andromeda. Quite likely, UGC 1810 will devour its galactic sidekick over the next billion years and settle into a classic spiral form.

    Is there a big chart that you can lob these into, so you can have the known universe on your bedroom ceiling?
