M51 La galaxie du tourbillon M51, aussi connue comme la galaxie du Tourbillon est un couple de galaxies, à environ 27,4 millions d' a.l. de la Terre dans la constellation Chiens de chasse, composé d'une galaxie spirale régulière massive dont le diamètre est estimé à 100 000 années-lumière et d'une petite galaxie irrégulière. Elle a été découverte en 1773 par Charles Messier.
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. The two galaxies appear to orbit each other at a projected separation of 147,000 light years. NGC 3718 seems to have a rudimentary bar and spiral structure although it is recognized as a peculiar galaxy and as such is listed within Arp's Atlas of Peculiar Galaxies. via Dark Matter on Facebook
Thor’s Helmet Nebula - NGC 2359 (also known as Thor's Helmet) is an emission nebula in the constellation Canis Major. The nebula is approximately 15,000 light-years away and 30 light years in size. The central star is the Wolf-Rayet star HD 56925, an extremely hot giant thought to be in a brief, pre-supernova stage of evolution
The Sombrero Galaxy (also known as M104 or NGC 4594) is an unbarred spiral galaxy in the constellation Virgo located 28 million light years from Earth. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk. The dark dust lane and the bulge give this galaxy the appearance of a sombrero.
