ESO’s VLT Captures Unlikely Pair In Large Magellanic Cloud
2013-08-07 18:32:09

[ Watch the Video: ESO Captures Pair of Mysterious Glowing Gas Clouds ] Brett Smith for redOrbit.com – Your Universe Online A newly released image from the European Southern Observatory's Very Large Telescope (VLT) has exposed new details about the Large Magellanic Cloud (LMC), a galactic neighbor of the Milky Way. The LMC was discovered by its namesake, Ferdinand Magellan, when the explorer's famous trip to circumnavigate the globe took him through the southern hemisphere in...

Old Age Makes Monster Galaxies Picky Eaters

Brett Smith for redOrbit.com - Your Universe Online A new analysis from scientists at NASA's Jet Propulsion Laboratory (JPL) revealed that supermassive galaxies have stopped cannibalizing their neighbors over the past few billion years. The finding calls current models for galactic growth into question. "We've found that these massive galaxies may have started a diet in the last 5 billion years, and therefore have not gained much weight lately," said Yen-Ting Lin of the Academia Sinica...

New Weapon Hunt For Dark Matter Energy
2013-08-02 13:06:59

John P. Millis, PhD for redOrbit.com - Your Universe Online The search for dark matter - and the even more mysterious dark energy - has both captivated and frustrated the minds of cosmologists and astronomers. There are the obvious reasons: by definition these phenomenon are difficult, if not impossible, to observe directly, and their effects can often be so subtle that making precise enough measurements proves a technical challenge. To overcome these difficulties, a team from the...

Exploring Hidden Milky Way
2013-08-01 08:48:11

John P. Millis, PhD for redOrbit.com - Your Universe Online Understanding how the Milky Way formed is one of the central scientific questions in astronomy. However, given the scale and complexity of the galaxy, there is a lot to consider. One of the ways researchers have found to tell the story of our galaxy's history is to create a detailed stellar census, analyzing spectra of large numbers of stars. "A star's spectrum is a powerful tool for learning about the star - it tells us key...

[ Watch the Video: Zoom into 47 Tucanae ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using NASA's Hubble Space Telescope are tracking the orbital motion of 33,000 stars in one of the Milky Way's oldest globular clusters. The team will be using the space observatory to track the orbital motion of 33,000 stars within globular cluster 47 Tucanae, which sits over 16,000 light-years away from Earth. "When analyzing the motions of stars, the longer the time baseline...

SOFIA AIrborne Telescope Heading South To New Zealand
2013-07-18 18:30:35

Lee Rannals for redOrbit.com - Your Universe Online NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) telescope has moved south to New Zealand for the next two weeks to take advantage of the Southern Hemisphere's orientation. The space agency said the airborne observatory would be utilizing its southern position to take advantage of studying celestial objects that are difficult or impossible to see in the northern sky. SOFIA is a telescope attached to a modified Boeing...

Milky Way Black Hole Rips Apart Gas Cloud
2013-07-17 10:54:47

[ Watch the Video: Simulation of Gas Cloud Being Ripped Apart By Black Hole ] Lee Rannals for redOrbit.com - Your Universe Online The European Southern Observatory's (ESO) Very Large Telescope (VLT) has helped astronomers catch a supermassive black hole ripping apart a gas cloud for the first time. Astronomers writing in the Astrophysical Journal say the gas cloud being ripped apart by the Milky Way's supermassive black hole is now so stretched that its front portion has passed the...

Aircraft Telescope Images Ring Of Dust Surrounding Black Hole
2013-07-10 13:34:10

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using a telescope attached to a modified Boeing 747SP aircraft have captured new images of a ring of gas and dust seven light-years in diameter surrounding the super-massive black hole at the center of the Milky Way. The team used NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) to capture images of our galaxy's circumnuclear ring (CNR), as well as a neighboring cluster of extremely luminous young stars known...

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...
