Spiral Galaxy NGC 1672 from Hubble: Spiral galaxy NGC 1672, pictured here, was captured in spectacular detail by the orbiting Hubble Space Telescope. Visible are dark filamentary dust lanes, young clusters of bright blue stars, red emission nebulas of glowing hydrogen gas, a long bright bar of stars across the center, and a bright active nucleus that likely houses a supermassive black hole. NGC 1672 spans about 75,000 light-years across and appears toward the constellation of the…
NGC 6240 A giant gas cloud spanning 300,000 light years with a mass of 10 billion Suns inside the galaxy merger system NGC 6240. This collision involves two spiral galaxies about the size of the Milky Way, each containing a supermassive black hole in the center, which are on their way to form an even more massive black hole.
Ring Galaxy NGC 922 was formed by the collision of two galaxies which triggered the formation of new stars in shape of a ring. Some of these were massive stars that evolved and collapsed to form black holes. (NASA, Chandra, 12/05/12) by NASA's Marshall Space Flight Center
NASA's Hubble Space Telescope shows a rare view of a pair of overlapping galaxies, called NGC 3314. The two galaxies look as if they are colliding, but they are actually separated by tens of millions of light-years, or about ten times the distance between our Milky Way and the neighboring Andromeda galaxy. The chance alignment of the two galaxies, as seen from Earth, gives a unique look at the silhouetted spiral arms in the closer face-on spiral, NGC 3314A.
