Astronomers Discover 7 Primitive Galaxies
2012-12-13 08:30:25

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered seven primitive galaxies that formed more than 13 billion years ago, during the Universe's infancy. The find includes a candidate galaxy that could hold the record for the most distant galaxy ever found. Scientists made the new discoveries using the Hubble Space Telescope's Hubble Ultra Deep Field project, which aims to improve our understanding of the early Universe. Astronomers are looking back at...

WASHINGTON, Dec. 12, 2012 /PRNewswire-USNewswire/ -- Using NASA's Hubble Space Telescope, astronomers announced Dec. 12 they have seen further back in time than ever before and have uncovered a previously unseen population of seven primitive galaxies that formed more than 13 billion years ago, when the universe was less than 3 percent of its present age. The deepest images to date from Hubble yield the first statistically robust sample of galaxies that tells how abundant they were close to...

ESO Installs New Instrument Onboard VLT
2012-12-12 07:57:44

Lee Rannals for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) has tested out its latest instrument called KMOS on its Very Large Telescope (VLT) at the Paranal Observatory in Chile. The instrument, K-band Multi-Object Spectrograph (KMOS), is capable of observing 24 objects at the same time in infrared light, and study the structure simultaneously within each one. ESO said KMOS will help to provide crucial data to help understand how galaxies grew and...

Spotting Distant Galaxy Clusters With WISE
2012-12-07 05:33:49

April Flowers for redOrbit.com - Your Universe Online As grand and colorful as it is, our solar system is a fleck in the grander cosmos. Our Milky Way galaxy has hundreds of billions of solar systems, yet it is only just a drop in the sea of galaxies. Galaxy clusters, the rarest and largest of galaxy groupings, can be the hardest to find, which is where NASA's Wide-field Infrared Survey Explorer (WISE) becomes helpful. So far, the mission's all-sky infrared maps have revealed one...

First Stars Born Short 750 Million Years After The Big Bang
2012-12-06 12:30:42

April Flowers for redOrbit.com - Your Universe Online The universe has had traces of heavy elements such as carbon and oxygen as far back in time as astronomers have been able to see. Elements such as these were originally churned from the explosion of massive stars. They formed the building blocks for planetary bodies, and eventually for life on Earth. Peering back far in time, a research team from MIT, Caltech, and the University of California at San Diego (UCSD) found matter...

Hubble Images Rare Spiral Galaxy With An Unusual Form
2012-12-06 09:19:14

[ Video 1 ] | [ Video 2 ] | [ Video 3 ] Lee Rannals for redOrbit.com - Your Universe Online A new Hubble Space Telescope image has been unveiled of NGC 922, revealing the cosmic structure to be an unusual spiral galaxy. The ring structure and distorted spiral shape of NGC 922 was imaged with NASA's Chandra X-ray Observatory to reveal even more chaos in the form of ultra luminous X-ray sources. The galaxy's unusual form is due to a cosmic bulls eye millions of years ago. A smaller...

Andromeda Project Wants Your Help Searching For Star Clusters
2012-12-05 13:08:22

Lee Rannals for redOrbit.com - Your Universe Online A new project, named The Andromeda Project, is asking the public's help to search through Hubble Space Telescope images to identify star clusters and increase our understanding of how galaxies evolve. The new project is a collaboration between scientists at the University of Washington, the University of Utah and other partners, aiming to study thousands of high-resolution Hubble images. “It´s an amazing opportunity to...

Green Bean Galaxy, A New Class Of Galaxy
2012-12-05 06:03:50

[ Watch the Video: The Green Bean Galaxy J2240 ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the European Space Observatory's Very Large Telescope (VLT) have identified a new galaxy class. The "green bean galaxies" have an unusual appearance, glowing in intense light emitted from the surroundings of monster black holes. The galaxies are amongst the rarest objects in the universe, and in the case of green bean galaxies, the entire galaxy glows, not just...

Astronomers Take Starburst Galaxy Census
2012-12-04 13:02:44

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have taken a census of hundreds of previously unseen starburst galaxies, revealing high star-formation rates across the Universe. The team used the European Space Agency's Herschel space observatory and ground-based W. M. Keck Observatory to make the observation. Starburst galaxies give birth to hundreds of solar masses' worth of stars every year, while galaxies like our Milky Way produce only one Sun-like star per year....

Hubble Sets Dark Matter Record Straight
2012-11-29 19:24:08

Lee Rannals for redOrbit.com — Your Universe Online A new observation of Abell 520 using the Hubble Space Telescope has helped astronomers determine that the core of the galaxy cluster is not over-dense in dark matter after all. Astronomers earlier this year spotted an overabundance of dark matter in the heart of the galaxy cluster. This observation was puzzling because dark matter and galaxies should be anchored together. Scientists have evidence that dark matter is...

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.

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...
