[ Watch The Video: Zooming in on the Bright Star Cluster Messier 7 ] ESO Messier 7, also known as NGC 6475, is a brilliant cluster of about 100 stars located some 800 light-years from Earth. In this new picture from the Wide Field Imager on the MPG/ESO 2.2-meter telescope it stands out against a very rich background of hundreds of thousands of fainter stars, in the direction of the center of the Milky Way. At about 200 million years old, Messier 7 is a typical middle-aged open...

[ Watch the Video: Large Magellanic Cloud Rotation Cycle ] Lee Rannals for redOrbit.com - Your Universe Online Scientists using NASA's Hubble Space Telescope found that the Large Magellanic Cloud (LMC) completes a rotation every 250 million years. The team used Hubble to measure the average motion of hundreds of individual stars in the nearby galaxy, which is located about 170,000 light-years from Earth. "Studying this nearby galaxy by tracking the stars' movements gives us a...

WASHINGTON, Feb. 18, 2014 /PRNewswire-USNewswire/ -- Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) According to their analysis, the central part of the neighboring galaxy, called the Large Magellanic Cloud (LMC), completes a rotation every 250 million years. It takes our sun the same...

Astronomer Discovers Hydrogen River Flowing Into Nearby Galaxy
2014-01-28 09:52:49

April Flowers for redOrbit.com - Your Universe Online What might be a never-before-seen river of hydrogen flowing through space has been discovered by West Virginia University astronomer, D.J. Pisano, using the National Science Foundation's (NSF) Robert C. Byrd Green Bank Telescope (GBT). A study, published in the Astronomical Journal, reveals that this river is a faint, very tenuous filament of gas, which is streaming into the nearby galaxy, NGC 6946. Understanding this may help...

FIRE Project Explains Galactic Masses
2014-01-23 09:00:42

April Flowers for redOrbit.com - Your Universe Online A puzzling contradiction has challenged astrophysicists for decades: many galactic wind models—which are simulations of how matter is distributed in the universe—predict that most of the "normal" matter exists in stars at the center of galaxies. However, these stars actually only account for less than 10 percent of the matter in the universe. Now, new simulations have revealed insight into this mismatch between models and reality,...

ESA Confirms Inside Out Model Milky Way

[ Watch the Video: Inside-out Formation Of The Milky Way ] Brett Smith for redOrbit.com - Your Universe Online New research from the European Space Agency's (ESA) Gaia-ESO project has confirmed previous theories on the inside-out development of the Milky Way, with the inner regions of the galaxy’s disc being the first to form. According to their report in the astronomical database Astro-ph, the study researchers reached their conclusions using observations taken with the 8-meter...

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...

Hubble Detects Faintest-Ever Early Universe Galaxies

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...
