massive Star forming cluster discovered

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Smithsonian's Submillimeter Array (SMA) have discovered a giant star-forming region. Known as W49A, the region is located 36,000 light-years away from Earth on the opposite side of the Milky Way. Astronomers say the star-forming region shines 100 times brighter than the Orion nebula. In order to view W49A, astronomers had to aim SMA through dusty fog, after which the telescope helped reveal an active site of star...

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...

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...

Milky Way's Black Hole Shows Off It's Jet Of High-Energy Particles
2013-11-21 10:21:13

Brett Smith for redOrbit.com - Your Universe Online Many supermassive black holes emit a jet of high-energy particles as a byproduct of engulfing large quantities of mass and energy, and NASA researchers have just discovered that the supermassive black hole at the center of the Milky Way is no different. Using observations from NASA's Chandra X-ray Observatory and the National Science Foundation's Very Large Array (VLA) radio telescope, a team of Chinese and American astrophysicists...

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 Reveals First Visual Evidence Of Milky Way's Formative Years
2013-11-14 16:35:20

HubbleSite NASA's Hubble Space Telescope has provided the first visual evidence showing how our home galaxy, the Milky Way, assembled itself into the majestic pinwheel of stars we see today. Perusing Hubble's deep-sky surveys, astronomers traced 400 galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years. "For the first time we have direct images of what the Milky Way looked like in the past," said study co-leader Pieter G. van Dokkum...

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 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...

At a distance of 3.9 Mpc from the Milky Way, the Sculptor Group is one of nearest groups of galaxies to the Local Gropu. Sculptor is made up of a loose group of galaxies near the south galactic pole. The Sculptor Galaxy (NGC 253) and a few other galaxies form a gravitationally-bound core in the center of this group, however, since they are only weakly bound the group may also be described as a filament. There also some other galaxies associated with the group but not gravitationally...

Aquila (the Eagle) Constellation -- Location: Northern Hemisphere; Coordinates: Right Ascension: 20h; Declination: 05; Source: Various cultures - Greek, Arab, Persian, Indian, Japanese, Chinese, Korean The story behind the name In the ancient Middle Eastern and Mediterranean cultures, the constellation Aquila is seen as the shape of a flying bird. The pattern contains three prominent stars that can be seen to outline the wings of a bird, but are also the focus of quite different myths...
