Mysterious Radio Bursts May Originate From Nearby Flaring Stars
2013-12-13 04:17:34

redOrbit Staff & Wire Reports - Your Universe Online Extremely quick, extremely bright radio pulses known as “fast radio bursts” may originate from flaring stars located within our own galaxy, researchers from the Harvard-Smithsonian Center for Astrophysics (CfA) claim in a new study. Based on their characteristics, scientists had believed that these radio bursts came from galaxies located billions of light-years away. However, the pulses – which typically only last for...

Starburst Galaxy M82 - An Up Close And Personal Look
2013-12-10 04:23:24

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have managed to get an up close and personal look at the nearby starburst galaxy M82, detecting concentrations of dense molecular gas surrounding regions of intense star formation and streams of material exiting the galaxy’s disk, the National Radio Astronomy Observatory (NRAO) announced Monday. The new data comes courtesy of the high-frequency Robert C. Byrd Green Bank Telescope (GBT), the world's largest,...

More Than Half A Million Galaxies Identified And Classified By The ALHAMBRA Project
2013-12-02 12:15:47

RUVID The ALHAMBRA project, led by researchers from the Instituto de Astrofísica de Andalucía and in which the University of Valencia has participated, has identified and classified more than half a million galaxies, after seven years of close observation of the universe from the Observatory of Calar Alto (CAHA, Almería) and thanks to a technique that breaks the stars energy in their colors through astronomical filters. In addition, this research has also allowed calculating the...

Milky Way Seen More Clearly Than Ever Thanks To New 3D Map Of The Stars
2013-11-29 04:10:22

Alan McStravick for redOrbit.com - Your Universe Online The Milky Way galaxy recently got a little easier to understand. A group of astronomers created a new 3D map of the stars that reside in the center of the Milky Way which shows, more clearly than ever, the bulge located at the core of our galaxy. Prior to this new representation it was widely believed the stars in the core orbited in a sort of banana shape. However, scientists, publishing this week in the journal Monthly Notices of...

Ancient Brown Dwarfs
2013-11-21 15:05:41

John P. Millis, PhD for redOrbit.com - Your Universe Online The galaxy is a diverse place, containing stars, planets, nebulous gas, black holes, and all matter of other objects, some of which we still do not understand. But among this vast array sits an object that is neither a star, nor a planet. These brown dwarfs have masses only a fraction of that of our Sun, but are still at least 13 times more massive than Jupiter. But because of the lack of substantial fusion, the surface of...

Three Primordial Galaxies Found Merging Near ‘Cosmic Dawn’
2013-11-21 13:36:25

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have found a group of primitive galaxies 13 billion light-years away sitting inside a blob of gas. A team using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope and NASA’s Hubble Space Telescope discovered three infant galaxies merging inside a giant bubble of hot ionized gas. The object, known as Himiko, is 10 times larger than typical galaxies discovered from this era and is comparable in size to our...

WISE Catalog And Atlas Just Got Wiser
2013-11-16 04:55:07

April Flowers for redOrbit.com - Your Universe Online A new and improved atlas and catalog, brimming with data on three-quarters of a billion objects detected during two full scans of the sky, were released by NASA on Friday from their Wide-field Infrared Survey Explorer (WISE) mission. In 2010, WISE scanned the entire sky in infrared light, snapping a dozen pictures of every star and galaxy. The spacecraft ran out of the coolant needed to chill some of its heat-seeking detectors in...

Cosmic Deception: One Galaxy Is Actually Two
2013-11-15 03:59:13

Alan McStravick for redOrbit.com - Your Universe Online My fifth grade teacher, Elizabeth Titterton, was responsible for teaching me the order of the planets in our solar system. A simple pneumonic ingrained in me an immutable truth that I carry to this day. "My Very Excellent Mother Just Served Us Nesselrode Pie." Of course, the ‘P’, representing Pluto, has been recast as simply a ‘minor’ planet, somehow stripping me of the concept of absolute truth for the rest of my life. And...

Hubble Sees Old And Mysterious Cluster
2013-11-14 12:17:16

[ Watch The Video: A Rare and Exotic Intermediate-Mass Black Hole ] NASA/ESA Hubble Space Telescope The NASA/ESA Hubble Space Telescope has captured the best ever image of the globular cluster Messier 15, a gathering of very old stars that orbits the center of the Milky Way. This glittering cluster contains over 100 000 stars, and could also hide a rare type of black hole at its center. This multi-colored firework display is a cluster of stars known as Messier 15, located some...

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies. Credit: NASA/Wikipedia What is Cosmology? I once commented to an acquaintance that I was fascinated by the field of Cosmology, and mused that if I had more time, I...

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 two Magellanic Clouds (or Nubeculae Magellani), composed of the Large Megellanic Cloud and the Small Magellanic Cloud, are irregular dwarf galaxies visible in the southern hemisphere. They are members of our Local Group and orbit the Milky Way galaxy. Persian astronomer Al Sufi, in 964, was the first to have written anything about the Magellanic Clouds proving they have been known since early time amongst the Middle East peoples. Sufi, in his Book of Fixed Stars, calls the clouds...

The M96 Group (also known as the Leo I Group), one of many in the Virgo Supercluster, is located within the Leo constellation and contains between 8 and 24 galaxies, including three Messier objects. The Leo Triplet, which is physically near M96 Group, and M96 may actually be separate parts of a much larger group.

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...
