NASA – VV 340, also known as Arp 302, provides a textbook example of colliding galaxies seen in the early stages of their interaction. The edge-on galaxy near the top of the image is VV 340 North and the face-on galaxy at the bottom of the image is VV 340 South. Millions of years later these two spirals will merge — much like the Milky Way and Andromeda will likely do billions of years from now. Data from NASA’s Chandra X-ray Observatory (purple) are shown here along with optical data from the Hubble Space Telescope (red, green, blue). VV 340 is located about 450 million light years from Earth.

The red giant AFGL 3068 is dying a beautiful death. Like all red giants, as they expand they spew their outer layers into space in a spherical shape. What’s unique about AFGL3068 however, is that it’s actually a binary star — two stars orbiting each other. Due to the orbits of the two stars, the material that’s ejected isn’t able to expand into a sphere, but in this amazingly perfect (and awesomely huge at 3 trillion kilometers!) spiral.
