ESA Releases Hubble Image Of Messier 83, A Galaxy With Two Hearts
2014-01-10 06:45:29

April Flowers for redOrbit.com - Your Universe Online A new image released from the ESA and NASA jointly-operated Hubble Space Telescope features the spiral galaxy Messier 83, also known as the Southern Pinwheel Galaxy. Messier 83, which is one of the largest and closest barred spiral galaxies to us, has hosted a large number of supernova explosions, and is thought to have a double nucleus at its core. The image was released this week at the 223rd meeting of the American Astrophysical...

ESA The face-on Pinwheel spiral galaxy is seen at ultraviolet wavelengths in this image taken by ESA´s XMM-Newton space telescope. Also known as M101, the galaxy lies 21 million light-years away in the constellation Ursa Major. It measures 170 000 light-years across — nearly twice the diameter of our own Milky Way Galaxy — and contains at least a trillion stars. About a billion of these stars could be similar to our own Sun. More often seen in visible light, here the...

Image 1 - Supernova Reaching Its Peak Brightness Thursday And Friday
2011-09-08 13:19:14

Astronomers will be losing sleep as they wait on a newly discovered supernova to reach its peak in brightness on Thursday and Friday. The exploding star is about 21 million light years away and was first spotted by telescopes August 23. It is the closest of its kind to be seen in four decades and is located in the "Pinwheel Galaxy" above the Big Dipper. Amateur star-gazers could even equip themselves with 20x80 binoculars to help see the exploding star. Astronomers say that the...

A prodigious pinwheel shines in the darkness ESO's Wide Field Imager has captured the intricate swirls of the spiral galaxy Messier 83, a smaller look-alike of our own Milky Way. Shining with the light of billions of stars and the ruby red glow of hydrogen gas, it is a beautiful example of a barred spiral galaxy, whose shape has led to it being nicknamed the Southern Pinwheel. This dramatic image of the galaxy Messier 83 was captured by the Wide Field Imager at ESO's La Silla Observatory,...

NASA -- Giant galaxies weren't assembled in a day. Neither was this Hubble Space Telescope image of the face-on spiral galaxy Messier 101 (M101). It is the largest and most detailed photo of a spiral galaxy that has ever been released from Hubble. The galaxy's portrait is actually composed of 51 individual Hubble exposures, in addition to elements from images from ground-based photos. The final composite image measures a whopping 16,000 by 12,000 pixels. The Hubble archived observations that...

PSU -- The Swift satellite's Ultraviolet/Optical Telescope (UVOT) has seen first light, capturing an image of the Pinwheel Galaxy, long loved by amateur astronomers as the "perfect" face-on spiral galaxy. The UVOT now remains poised to observe its first gamma-ray burst. Swift is a NASA-led mission dedicated to the gamma-ray burst mystery. These random and fleeting explosions likely signal the birth of black holes. With the UVOT turned on, Swift now is fully operational. Swift's two other...

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...

Pinwheel Galaxy -- Discovered by Pierre Mchain in 1781. M101 was discovered by Pierre Mchain on March 27, 1781, and added as one of the last entries in Charles Messier's catalog. It was the first "spiral nebula" identified as such by William Parsons, the third Earl of Rosse. Although extended 22 arc minutes on photos and quite bright, only the central region of this galaxy is visible in smaller telescopes, best at low powers. Suggestions of the spiral arms can be glimpsed in...
