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...

Spitzer Finds New Stars At Edge Of Milky Way
2013-06-06 09:48:09

April Flowers for redOrbit.com - Your Universe Online New images from NASA´s Spitzer Space Telescope reveal blooming stars at the fringe of the Milky Way galaxy, far from its crowded core. The images were collected as part of the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (Glimpse 360) project. Glimpse 360 is mapping the celestial topography of our galaxy and will make the map and a full 360-degree view of the Milky Way plane that will be available later this year....

Galactic Superwinds Power Up Gas Clouds In M82

redOrbit Staff & Wire Reports - Your Universe Online Shockwaves originating from the central starburst region of galaxy Messier 82 (M82) are most likely the source of bright clouds within a “cap” of gas clouds located some 40,000 light years away, astronomers have discovered. Kyoto University´s Dr. Kazuya Matsubayshi and an international team of colleagues observed the nearby starburst galaxy, which is located approximately 12 million light-years away in the...

Hubble Images Isolated Galaxy DDO 190
2012-08-18 06:55:57

redOrbit Staff & Wire Reports - Your Universe Online An image of an isolated galaxy located approximately nine million light years from the Milky Way has been captured using the Hubble Space Telescope, NASA officials announced on Friday. The picture features a relatively isolated, dwarf irregular galaxy known as DDO 190, which officials from the US space agency describe as relatively small and lacking in structure. The galaxy, which was identified and code named in honor of the...

Chandra Discovers Nearest Pair Of Supermassive Black Holes
2011-09-01 06:13:01

  Astronomers using NASA's Chandra X-ray Observatory discovered the first pair of supermassive black holes in a spiral galaxy similar to the Milky Way. Approximately 160 million light years from Earth, the pair is the nearest known such phenomenon. The black holes are located near the center of the spiral galaxy NGC 3393. Separated by only 490 light years, the black holes are likely the remnant of a merger of two galaxies of unequal mass a billion or more years ago. "If this...

A new Chandra X-ray Observatory image of Messier 82, or M82, shows the result of star formation on overdrive. M82 is located about 12 million light years from Earth and is the nearest place to us where the conditions are similar to those when the Universe was much younger with lots of stars forming. M82 is a so-called starburst galaxy, where stars are forming at rates that are tens or even hundreds of times higher than in a normal galaxy. The burst of star birth may be caused by a close...

Lowell Observatory astronomer Deidre Hunter and her team studies small, diffuse galaxies to learn about star formation in those regions and, perhaps, shed light on the birth of the first stars after the Big Bang When you picture a galaxy in your mind's eye, it's often a spiral with magnificent structure--long, swirling, milky-white arms of stars and gas. Lowell Observatory astronomer Deidre Hunter has spent most of the last 17 years methodically studying galaxies that you might not...

A U.S. astronomer says he discovered a galaxy in which gas is distributed over a much larger area than researchers expected to find. Macalester College Professor John Cannon said the giant disk dwarf galaxy he discovered has the largest size difference between stars and gas of any known galaxy. That finding, he said, is important for furthering the understanding of how galaxies form and how they remain stable over time. Cannon said data from the Kitt Peak National Observatory in Arizona and...

Astronomers think that there are enormous black holes at the centers of most, if not all, galaxies. These black holes, which can be millions or even billions of times more massive than the Sun, can greatly affect the galaxy and the environments around them. One way such black holes shape their surroundings is by generating powerful jets of high-energy particles. The jets, which are bright in radio waves, have been seen to push around the hot gas that envelopes the galaxy. When this happens,...

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
