hypervelocity star

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Most stars move around the galaxy in well-defined orbits, pulled under the influence of the Milky Way’s gravity. It is the predictable motion of the stars around the Milky Way’s supermassive black hole core that gives the galaxy its spiral structure. There are, of course, deviations from the norm, but on average the stars move at a leisurely pace of roughly 500,000 miles per hour. But this is not always the case. In...

elliptical galaxy M87
2014-04-30 12:25:17

Harvard-Smithsonian Center for Astrophysics The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour. The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey to nowhere. Its fate: to drift through the void between the galaxies for all time. "Astronomers have found runaway stars before, but this is the first time we've found a runaway star...

Caltech's Cosmic Web Imager Directly Observes "Dim Matter"
2014-04-30 03:53:16

Cynthia Eller, California Institute of Technology Caltech astronomers have taken unprecedented images of the intergalactic medium (IGM)—the diffuse gas that connects galaxies throughout the universe—with the Cosmic Web Imager, an instrument designed and built at Caltech. Until now, the structure of the IGM has mostly been a matter for theoretical speculation. However, with observations from the Cosmic Web Imager, deployed on the Hale 200-inch telescope at Palomar Observatory,...

Astronomers Discover Mature Galaxies In A Young Universe
2014-04-30 04:33:59

redOrbit Staff & Wire Reports - Your Universe Online With the assistance of the European Space Agency’s (ESA) Herschel Space Observatory, astronomers have located a young galaxy rotating in a calmer, more mature manner similar to more developed ones like the Milky Way. The galaxy, which has been dubbed S0901, has apparently completed the accumulation of its gas reservoir, the ESA explained in a statement Tuesday. When galaxies form, they build mass by gravitationally attracting...

Professional And Amateur Astronomers Join Together
2014-04-24 03:21:06

NASA Long before the term "citizen science" was coined, the field of astronomy has benefited from countless men and women who study the sky in their spare time. These amateur astronomers devote hours exploring the cosmos through a variety of telescopes that they acquire, maintain, and improve on their own. Some of these amateur astronomers specialize in capturing what is seen through their telescopes in images and are astrophotographers. What happens when the work of amateur...

Supercomputer Simulations Shed Light On How Black Holes Swallow Stars
2014-04-14 13:51:10

Brett Smith for redOrbit.com - Your Universe Online When a star orbits too close to a galaxy’s central supermassive black hole, it gets torn apart and sucked in by gravitational forces – a phenomenon known as an a tidal disruption. In a new study, researchers from Georgia Institute of Technology and the Max Planck Institute in Germany have used computational and theoretical models to describe the dynamics of these cosmic events that cause massive flares of light and energy....

New Image Shows Galactic Serial Killer
2014-04-02 13:48:59

[ Watch The Video: Panning Across The Galaxies NGC 1316 And 1317 ] ESO This new image from the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile shows two contrasting galaxies: NGC 1316, and its smaller neighbor NGC 1317. These two are quite close to each other in space, but they have very different histories. The small spiral NGC 1317 has led an uneventful life, but NGC 1316 has engulfed several other galaxies in its violent history and shows the battle scars....

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 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...

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...
