A Sagittarius Triplet (June 1 2012) Image Credit & Copyright: Martin Pugh These three bright nebulae are often featured in telescopic tours of the constellation Sagittarius and the crowded starfields of the central Milky Way. In fact, 18th century cosmic tourist Charles Messier cataloged two of them; M8, the large nebula left of center, and colorful M20 on the right. The third, NGC 6559, is above M8, separated from the larger nebula by a dark dust lane. #astronomy
M51: The Whirlpool Galaxy (June 2 2012) Image Credit & Copyright: Marco Burali, Tiziano Capecchi, Marco Mancini (Osservatorio MTM) Follow the handle of the Big Dipper away from the dipper's bowl until you get to the handle's last bright star. Then, just slide your telescope a little south and west and you might find this stunning pair of interacting galaxies, the 51st entry in Charles Messier famous catalog. (...) #astronomy
pair of interacting galaxies called arp 273. the larger of the spiral galaxies, known as ugc 1810, has a disk that is distorted into a rose-like shape by the gravitational tidal pull of the companion galaxy below it, known as ugc 1813. ~ credit: nasa, esa, and the hubble heritage team (stsci/aura)
This floating ring is the size of a galaxy. In fact, it is part of the Sombrero Galaxy, one of the largest galaxies in the nearby Virgo Cluster of Galaxies. The dark band of dust that obscures the mid-section of the Sombrero Galaxy in optical light actually glows brightly in infra-red light. The above image, digitally sharpened, shows the infra-red glow, recently recorded by the orbiting Spitzer Space Telescope, superposed in false-color on an existing image taken by NASA's Hubble Space
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))
M95 also catalogued as NGC 3351 is a barred spiral galaxy about 38 million light-years from Earth, appearing in the constellation Leo. A bonus, follow along the spiral arm unwinding down and to the right to see the slightly bluish supernova SN 2012aw, discovered on March 16, 2012.
