Hubble's Greatest Hits

Hubble's Greatest Hits - This edge-on view of galaxy ESO 510-G13 shows how colliding galaxies spawn the formation of new generations of stars. The dust and spiral arms of normal spiral galaxies, like our own Milky Way, appear flat when viewed edge-on. By contrast, the strong warping of ESO 510-G13 indicates it has recently undergone a collision with a nearby galaxy and is in the process of swallowing it. Over millions of years, the disturbances will die out, and ESO 510-G13 will become a…

NGC 3718 (Arp 214) Distance: 42.4 Million Light Years NGC 3718 and its companion NGC 3729 are physically related members of the Ursa Major galaxy cluster. via Facebook (396×559)

The Heart Nebula, IC 1805, Sh2-190, lies some 7500 light years away from Earth and is located in the Perseus arm of the Galaxy in the constellation Cassiopeia.

This little spiral, known as NGC 4102, has a different kind of appeal, with its tightly-wound spiral arms and understated, but charming, appearance.

A beautiful new image of two colliding galaxies has been released by NASA's Great Observatories. The Antennae galaxies, located about 62 million light-years from Earth, are shown in this composite image from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red).
