APOD #1
These two galaxies, NGC 5426 and NGC5427, are about to collide. They are collectively known as Arp 271 and cover about 130,000 light years. They are close to 90 million lightyears away toward the Gemini constellation. Normally, when this happens, a bigger galaxy eats a smaller one, but these are about the same size and are relatively the same in nature. I think that the two component stars may collide to form one bigger one, or just start to orbit each other. Maybe they'll just pass through each other. New stars will definitely be born in the compression of gasses of the two galaxies. There are suspicions that this same effect will happen between The Milky Way and the Andromeda galaxy, which is both exciting and nerve-racking for Earth.
