Latest Spiral galaxies Stories
[ Video 1 ] | [ Video 2 ] | [ Video 2 ] NASA/ESA Hubble Heritage Team The NASA/ESA Hubble Space Telescope – with a little help from an amateur astronomer – has produced one of the best views yet of nearby spiral galaxy Messier 106. Located a little over 20 million light-years away, practically a neighbor by cosmic standards, Messier 106 is one of the brightest and nearest spiral galaxies to our own. Despite its appearance, which looks much like countless other galaxies, Messier...
Brett Smith for redOrbit.com - Your Universe Online Studying the physics of the universe can be a controversial and often contradictory proposition, with theories and calculations often not matching with observations. However, new research from Leibniz Institute for Astrophysics Potsdam in Germany, has shed some light on one situation involving differences between theory and observation. Scientists at the institute have found that a phenomenon known as “cosmic web stripping” is...
redOrbit Staff & Wire Reports – Your Universe Online Through detailed study of the constellation Ursa Major, astronomers have reportedly found two new clouds of hydrogen gas, one which is a faint dwarf galaxy, and the other which could be a proto dwarf galaxy that has not yet had a chance to form any stars. The research team, led by Case Western Reserve University astronomy professor Chris Mihos, have dubbed the gas clouds – which are formally named G1425+5235 and G1355+5439...
redOrbit Staff & Wire Reports - Your Universe Online Astronomers have reportedly discovered the largest known structure in the universe – a formation so massive it would take a vehicle that was moving at light speed roughly four billion light years to cross it, the Royal Astronomical Society (RAS) announced on Thursday. The structure is a large quasar group (LQG), or a formation that contains the nuclei of galaxies from the earliest days of the universe’s existence. These quasar...
redOrbit Staff & Wire Reports - Your Universe Online While searching for data looking for star-forming regions around a galaxy located more than 200 million light years away, researchers have accidentally discovered that it is, in fact, the largest known spiral galaxy in the entire universe. As reported Friday by BBC News reporter Jason Palmer, a research assistant from NASA’s Goddard Space Flight Center and colleagues from the Catholic University of America (CUA), the University...
WASHINGTON, Jan. 10, 2013 /PRNewswire-USNewswire/ -- The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil has crowned it the largest-known spiral, based on archival data from NASA's Galaxy Evolution Explorer (GALEX) mission. GALEX has since been loaned to the California Institute of Technology in Pasadena, Calif. (Logo:...
[ Watch the Video: HII Region Discovery Survey ] redOrbit Staff & Wire Reports - Your Universe Online A new survey of the Milky Way has uncovered hundreds of previously-unknown regions of massive star formation, including some of the most distant located to date in the galaxy, researchers revealed on Wednesday. Using the National Science Foundation's (NSF) Green Bank Telescope (GBT) in West Virginia and the Arecibo Observatory Telescope in Puerto Rico, as well as data from the...
redOrbit Staff & Wire Reports - Your Universe Online Astronomers affiliated with the Harvard-Smithsonian Center for Astrophysics (CfA) have discovered a new structure in the Milky Way – a lengthy tendril comprised of dust and gas. The tendril – or “bone” as they refer to it – is long and slender, drawing comparisons to the fibula, or calf bone. In a statement, lead author Alyssa Goodman stated that this marks the first time that scientists have been able to locate such a...
redOrbit Staff & Wire Reports - Your Universe Online Using the airborne telescope on the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers have learned that a series of recent starbursts had taken place in the central region of the Milky Way, NASA officials reported on Tuesday. According to the US space agency, our galaxy’s nucleus is home to a black hole with four million times the mass of the sun. It is orbited by a large disk of dust and gas, and holds...
WASHINGTON, Jan. 8, 2013 /PRNewswire-USNewswire/ -- Researchers using the Stratospheric Observatory for Infrared Astronomy (SOFIA) have captured new images of a ring of gas and dust seven light-years in diameter surrounding the supermassive black hole at the center of the Milky Way, and of a neighboring cluster of extremely luminous young stars embedded in dust cocoons.

The Virgo Cluster consists of galaxies at a distance of around 59 Mly away in the constellation Virgo. Containing between 1300 to 2000 galaxies the Virgo Cluster is the heart of the Local Supercluster. Its mass is estimated at 1.2 × 1015 M☉ out to 8 degrees of the cluster's center or a radius of about 2.2 Mpc. Most of the brighter galaxies in the cluster were discovered by Charles Messier in the late 1770's and early 1780's, including the giant elliptical Messier 87. Messier...
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...
The M81 Group, containing the well known galaxies Messier 81 and Messier 82, is a group of galaxies within the constellation Ursa Major. Along with Messier 81 and 82 are several other galaxies with apparent brightness. The center, located at an approximate distance of 3.6 Mpc, is one of the nearest groups to the Local Group. The total estimated mass of the group is (1.03 ± 0.17) × 1012M☉. The Virgo Supercluster contains the M81 Group, the Local Group, and some other nearby...
The Local Group, compromising more than 30 galaxies (including dwarf galaxies and the Milky Way), is a group of galaxies with a gravitational center located somewhere between the Milky Way and the Andromeda Galaxy. With a binary (dumbbell) shape and a total mass of (1.29 ± 0.14) × 1012M the Local group covers a 10 million light-year diameter. The local group is part of the Virgo Supercluster. The two largest galaxies in the group are the Milky Way and the Andromeda both Spiral...
Stephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies which four form the first compact galaxy group ever discovered. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory and is the most studied of all the compact galaxy groups. NGC 7320, which has extensive H II regions, is the brightest member of the visual grouping and is where active star formation is occurring. Hickson Compact Group 92, which contains four of the five...
