The largest known galaxy

IC1101 is jaw droppingly huge. A vast and diffuse halo of over a trillion stars, large enough that it would encompass the Milky Way and its two nearest major galactic neighbors, Andromeda and Triangulum. Which is something considering that the Triangulum is roughly 3 million light years distant and Andromeda 2.5 mly away. Yeeesh!




Speaking of galaxies: If you want to see something gorgeous, NASA has done up a sequence of images for what our night sky will look like in a few billion years when the Milky Way and Andromeda galaxies meet and merge.

Sadly, Earth will likely be a husk of its former self at that point, but this new sky will be awesome to behold, at least if our machine descendants are around to witness it.
