VV 340 in 60 Seconds
Narrator (April Hobart, CXC): VV 340, also known as Arp 302, is a textbook example of
colliding galaxies seen in the very early stages of their interaction. Astronomers have
named the edge-on galaxy at the top VV 340A, and VV 340B is the face-on galaxy at the bottom
of the image. Millions of years later these two spirals will merge - much like the Milky
Way and Andromeda will likely do billions of years from now. Chandra data are being
shown here with optical data from Hubble. VV 340 is located about 450 million light
years from Earth.
