Brett Smith for redOrbit.com - Your Universe Online Astronomers have been observing the Whirlpool Galaxy since the 18th century, but they've never seen it like this. A new One Degree Imager (ODI) camera at the Kitt Peak National Observatory in Arizona has captured stunning new images of the distant spiral galaxy in never-before-seen detail. When used with the WIYN 3.5-meter telescope at the observatory, the camera is able to provide images of the Whirlpool Galaxy and its companion...

Herschel opened its 'eyes' on June 14 and the Photoconductor Array Camera and Spectrometer obtained images of M51, "Ëœthe whirlpool galaxy' for a first test observation. Scientists obtained images in three colors which clearly demonstrate the superiority of Herschel, the largest infrared space telescope ever flown. This image shows the famous "Ëœwhirlpool galaxy', first observed by Charles Messier in 1773, who provided the designation Messier 51 (M51). This spiral...

NASA -- When NASA's Hubble Space Telescope was launched in 1990, astronomers anticipated great discoveries, ranging from finding black holes to looking back billions of years toward the beginning of time. Now, 15 years later, the versatile telescope continues to deliver exciting new science, including helping to prove the existence of dark energy, tracing enigmatic gamma-ray bursts to distant galaxies, and sampling the atmospheres of far-flung planets. To celebrate Hubble's 15th anniversary,...

The NGC 5866, located in the Draco constellation, is named after the galaxy with the highest magnitude however some catalogs list NGC 5907 as the brightest member. The M51 Group and the M101 Group are NGC 5866 closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them separate.

The M101 Group, one of many in the Virgo Supercluster, is located in Ursa Major and named after the brightest galaxy in the group, the Pinwheel Galaxy (M101). The group is composed mostly of members that are companions of the Pinwheel Galaxy. The M51 Group and the NGC 5866 Group are M101's closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them...

Whirlpool Galaxy -- Discovered 1773 by Charles Messier. The famous Whirlpool galaxy M51 was one of Charles Messier's original discoveries: He discovered it on October 13, 1773, when observing a comet, and described it as a "very faint nebula, without stars" which is difficult to see. Its companion, NGC 5195, was discovered in 1781 by his friend, Pierre Mchain, so that it is mentioned in Messier's 1784 catalog: `It is double, each has a bright center, which are separated 4'35". The two...

Sunflower Galaxy (M63) -- Discovered 1779 by Pierre Mchain. M63 was the very first discovery of a Deep Sky object by Messier's friend, Pierre Mchain, who caught it up on June 14, 1779. On the same day, Charles Messier included it in his catalog. The Sunflower galaxy M63 is one of the early recognized spiral galaxies, listed by Lord Rosse as one of 14 "spiral nebulae" discovered to 1850. It has been classified as of Hubble type Sb or Sc, displaying a patchy spiral pattern which can...
