NASA recently released an image of two galaxies colliding together in the formation of an enormous exclamation point.
NASA explained that, “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. 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 some 450 million light years away from earth (4.5 x 10+26). “Millions of years later these two spirals will merge—much like the Milky Way and Andromeda will likely do billions of years from now” (10+09).
The visible mass energy in a galaxy like ours (the Milky Way) is 10+58, and yet, incredibly, “These galaxies generate energy at a rate that is tens to hundreds of times larger than that emitted by a typical galaxy.”
