This diagram shows our cosmic address at a glance. We see our planetary system around the Sun, our stellar neighborhood in our galaxy, our galaxy in the local group of galaxies, and our group in the entire universe.
New picture of the Leo Triplet Galaxies showing the Tidal Tail of NGC 3628 - these galaxies can be introduced individually as NGC 3628 (left), M66 (bottom right), and M65 (top right). (credit & copyright: Thomas V. Davis (tvdavisastropix.com))
Hubble Photographs Cosmic FountainCredit: NASA, ESA and the Hubble Heritage Team (STScI/AURA)This interacting group contains several galaxies (called Arp 194), along with a "cosmic fountain" of stars, gas and dust that stretches over 100,000 light-years
At the top, large spiral galaxy NGC 1055, and the bottom spiral Messier 77, in this sharp cosmic view toward the aquatic constellation Cetus. The narrowed, dusty appearance of edge-on spiral NGC 1055 contrasts nicely with the face-on view of M77's bright nucleus and spiral arms. Both over 100,000 light-years across, the pair are dominant members of a small galaxy group about 60 million light-years away. M77 and NGC 1055 are separated by at least 500,000 light-years.
