A Tour of Perseus and Virgo Clusters
A Tour of Perseus and Virgo Clusters
Now researchers have direct evidence for just how that energy keeps the gas in the entire galaxy cluster so hot. (2014-10-31)


VV 340 in 60 Seconds

View/Listen
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.
