Latest Spiral galaxies Stories
United Press International reports that U.S. and Canadian astronomers say they've seen a spiral galaxy born in the early universe billions of years before that kind of galaxy should have formed. Los Angeles, CA (PRWEB) July 19, 2012 U.S. and Canadian astronomers say they've seen a spiral galaxy born in the early universe billions of years before that kind of galaxy should have formed. The distant spiral galaxy, observed by the Hubble Space Telescope, is being seen as it existed...
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...
Lee Rannals for redOrbit.com - Your Universe Online Astronomers from Canada and the U.S. have found that the Milky Way galaxy may have recently had an encounter with one of its surrounding smaller satellite galaxies. “We have found evidence that our Milky Way had an encounter with a small galaxy or massive dark matter structure perhaps as recently as 100 million years ago,” Larry Widrow, professor at Queen’s University in Canada, said in a press release. “We clearly observe...
Using an array of radio telescopes, researchers from Europe and Japan have discovered a submillimeter galaxy -- a type of galaxy that has intense star formation activity and is covered by large amounts of dust -- located approximately 12.4 billion light-years away. The international team of experts, which was led by Kyoto University Associate Professor Tohru Nagao, used the Atacama Large Millimeter/submillimeter Array (ALMA) in southern Chile to locate the galaxy, the researchers announced...
Black holes in the early universe needed a few snacks rather than one giant meal to fuel their quasars and help them grow, according to observations from NASA's Spitzer and Hubble space telescopes. Quasars are the brilliant beacons of light that are powered by black holes feasting on captured material, and in the process, heating some of the matter to millions of degrees. The brightest quasars reside in galaxies distorted by collisions with other galaxies. These encounters send lots of gas...
[ Video 1 ] | [ Video 2 ] The NASA/ESA Hubble Space Telescope has produced a highly detailed image of a pair of overlapping galaxies called NGC 3314. While the two galaxies look as if they are in the midst of a collision, this is in fact a trick of perspective: the two just happen to appear in the same direction from our vantage point. NGC 3314A and B might look like they are in the midst of a galactic pile-up, but they are in fact separated by tens of millions of light years of void....
Lee Rannals for redOrbit.com According to recent studies with the National Science Foundation's Green Bank Telescope (GBT), a couple celestial neighbor galaxies may have had a close encounter with each other billions of years ago. Astronomers confirmed a disputed 2004 discovery of hydrogen gas streaming between the giant Andromeda Galaxy and the Triangulum Galaxy with their new study. "The properties of this gas indicate that these two galaxies may have passed close together in the...
[ Watch the Video ] NASA astronomers announced on May 31 that they can now predict with certainty the next major cosmic event to affect our galaxy, sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy. The Milky Way is destined to get a major makeover during the encounter, which is predicted to happen four billion years from now. It is likely the sun will be flung into a new region of our galaxy, but our Earth and solar system are in...
WASHINGTON, May 31, 2012 /PRNewswire-USNewswire/ -- NASA astronomers announced Thursday they can now predict with certainty the next major cosmic event to affect our galaxy, sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy.

Visible in the constellation of Andromeda, NGC 891 is located approximately 30 million light-years away from Earth. The NASA/ESA Hubble Space Telescope turned its powerful wide field Advanced Camera for Surveys towards this spiral galaxy and took this close-up of its northern half. The galaxy's central bulge is just out of the image on the bottom left. The galaxy, spanning some 100,000 light-years, is seen exactly edge-on, and reveals its thick plane of dust and interstellar gas. While...

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 M101 Group, one of many in the Virgo Supercluster, is located in Ursa Major and named after the brightest galaxy in the group, the Pinwheel Galaxy (M101). The group is composed mostly of members that are companions of the Pinwheel Galaxy. The M51 Group and the NGC 5866 Group are M101's closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them...
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...
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...
Stephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies which four form the first compact galaxy group ever discovered. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory and is the most studied of all the compact galaxy groups. NGC 7320, which has extensive H II regions, is the brightest member of the visual grouping and is where active star formation is occurring. Hickson Compact Group 92, which contains four of the five...
