Astronomers Say Supernova Will Be Visible From Earth Within 50 Years
2013-10-31 16:04:47

[ Watch the Video: Is There A Supernova In Your Future? ] Brett Smith for redOrbit.com - Your Universe Online A supernova is one of the most brilliant events to take place in the universe and astronomers at The Ohio State University have determined we will see one in the Milky Way Galaxy within the next 50 years. While the odds of actually seeing a star explode with the naked eye is very low during that time span, a supernova would be visible to specialized telescopes in the form of...

Spiral Galaxy Messier 106 Has A Secret
2013-02-05 10:47:02

[ Video 1 ] | [ Video 2 ] | [ Video 2 ] NASA/ESA Hubble Heritage Team The NASA/ESA Hubble Space Telescope — with a little help from an amateur astronomer — has produced one of the best views yet of nearby spiral galaxy Messier 106. Located a little over 20 million light-years away, practically a neighbor by cosmic standards, Messier 106 is one of the brightest and nearest spiral galaxies to our own. Despite its appearance, which looks much like countless other galaxies,...

Ancient Spiral Galaxy Observed By Astronomers

Lee Rannals for redOrbit.com - Your Universe Online A new discovery may help astronomers peer back in time to when spiral galaxies first began to take their shape. Scientists wrote in the journal Nature that they had found a surprising ancient spiral galaxy known as BX442. The galaxy was found by astronomers who first surveyed 300 distant galaxies using the Hubble Space Telescope. They followed up and confirmed it using detailed observations and analyzes from the W.M. Keck...

An assorted mix of colorful galaxies was released May 25 by NASA's Wide-field Infrared Survey Explorer mission, or WISE. The nine galaxies are a taste of what's to come. The mission plans to release similar images for the 1,000 largest galaxies that appear in our sky, and possibly more. "Galaxies come in all sorts of delicious flavors," said Tom Jarrett, a WISE team member at the Infrared Processing and Analysis Center, California Institute of Technology, in Pasadena, who studies...

NASA's Wide-field Infrared Survey Explorer has captured a new view of two companion galaxies -- a somewhat tranquil spiral beauty and its rambunctious partner blazing with smoky star formation. The unlikely pair, named Messier 81 and Messier 82, got to know each other a lot better during an encounter that occurred a few hundred million years ago. As they swept by each other, gravitational interactions triggered new bursts of star formation. In the case of Messier 82, also known as the Cigar...

ESO is releasing a beautiful image of the nearby galaxy Messier 83 taken by the HAWK-I instrument on ESO's Very Large Telescope (VLT) at the Paranal Observatory in Chile. The picture shows the galaxy in infrared light and demonstrates the impressive power of the camera to create one of the sharpest and most detailed pictures of Messier 83 ever taken from the ground. The galaxy Messier 83 is located about 15 million light-years away in the constellation of Hydra (the Sea Serpent). It spans...

Hubble has snapped a spectacular view of the largest "player" in the Leo Triplet, a galaxy with an unusual anatomy: it displays asymmetric spiral arms and an apparently displaced core. The peculiar anatomy is most likely caused by the gravitational pull of the other two members of the trio. The unusual spiral galaxy, Messier 66, is located at a distance of about 35 million light-years in the constellation of Leo. Together with Messier 65 and NGC 3628, Messier 66 is one third of the Leo...

Galaxies throughout the universe are ablaze with star birth. But for a nearby, small spiral galaxy, the star-making party is almost over. Astronomers were surprised to find that star-formation activities in the outer regions of NGC 2976 have been virtually asleep because they shut down millions of years ago. The celebration is confined to a few die-hard partygoers huddled in the galaxy's inner region. The explanation, astronomers say, is that a raucous interaction with a neighboring group of...

ESA's space-borne X-ray observatory, XMM-Newton, has carried out an exclusive observation of the galaxy Messier 82, for the "˜100 Hours of Astronomy' cornerstone project for the International Year of Astronomy 2009. The observatory was featured in the "˜Around the World in 80 Telescopes' live webcast last week. This European space telescope has been studying the sky in X-ray, optical and ultraviolet wavelengths simultaneously, since its launch in December 1999. The image...

There's an old saying in astronomy: "Galaxies are like people. They're only normal until you get to know them." That view is supported by a group of astronomers after using NASA's Hubble Space Telescope to study a large number of galaxies in our cosmic backyard. The detailed survey, called the ACS Nearby Galaxy Survey Treasury (ANGST) program, observed roughly 14 million stars in 69 galaxies. The survey explored a region called the "Local Volume," and the galaxy distances ranged from 6.5...

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.'
