Dark Matter Clues From The Center Of Our Galaxy
2014-04-03 13:57:46

[ Watch the Video: Fermi Data Hints At New Dark Matter Clues ] Francis Reddym, NASA Goddard Space Flight Center A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists at the Fermi National Accelerator Laboratory (Fermilab), the...

[ Watch The Video: Panning Across The Galaxies NGC 1316 And 1317 ] ESO This new image from the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile shows two contrasting galaxies: NGC 1316, and its smaller neighbor NGC 1317. These two are quite close to each other in space, but they have very different histories. The small spiral NGC 1317 has led an uneventful life, but NGC 1316 has engulfed several other galaxies in its violent history and shows the battle scars....

[ Watch the Video: 360-Degree View of the Milky Way ] Lawrence LeBlond for redOrbit.com - Your Universe Online NASA’s Spitzer Space Telescope has been busy studying stars, asteroids, galaxies and other outer space objects over the past 10 years and a University of Wisconsin team of scientists has now used more than two million images produced by Spitzer to create a virtual 360-degree mosaic of our Milky Way. The team presented the new interactive map Thursday at the TEDActive 2014...

ESA The largest census of dust in local galaxies has been completed using data from ESA’s Herschel space observatory, providing a huge legacy to the scientific community. Cosmic dust grains are a minor but fundamental ingredient in the recipe of gas and dust for creating stars and planets. But despite its importance, there is an incomplete picture of the dust properties in galaxies beyond our own Milky Way. Key questions include how the dust varies with the type of galaxy, and how...

What Lies Beyond: Astronomer Maps Galaxies Near Our Own
2014-03-11 13:13:33

Lee Rannals for redOrbit.com - Your Universe Online A new paper published in the Monthly Notices of the Royal Astronomical Society has broadened the view of what lies just past our galaxy. The Milky Way and Andromeda are dominant members of a small group of galaxies. However, not a lot has been known about the smaller galaxies that reside within our neighborhood in the universe. York University Physics & Astronomy Professor Marshall McCall was able to map out the bright galaxies...

Astronomers Use Cluster Of Galaxies As A Giant Telescope
2014-03-10 06:33:20

[ Watch the Video: A Telescope Bigger Than A Galaxy ] April Flowers for redOrbit.com - Your Universe Online On a starry night, around 400 years ago, Galileo turned his primitive spyglass toward the sky. In just a few nights, he learned more about the stars than all of the scientists and philosophers before him, combined. Since those historic nights, astronomers have operated under a single imperative: make bigger telescopes. The power of optics has grown a million-fold as the 21st...

Blood And Guts Spilled By Spiral Galaxy

[ Watch The Video: Zooming in on ESO 137-001 ] ESA/Hubble This new Hubble image shows ESO 137-001, a galaxy located in the southern constellation of Triangulum Australe (The Southern Triangle) — a delicate and beautiful spiral galaxy, but with a secret. This image not only captures the galaxy and its backdrop in stunning detail, but also something more dramatic — intense blue streaks streaming outwards from the galaxy, seen shining brightly in ultraviolet light. These...

Red Dead Redemption: Black Holes Bully Galaxies Into Submission
2014-02-26 15:13:15

Brett Smith for redOrbit.com - Your Universe Online Typically filled with only the oldest stars, which are relatively low in mass and appear red, giant elliptical galaxies have long baffled astronomers. These galaxies are mysteriously shut down with respect to star-forming activity – a status scientists refer to as “red and dead.” These galaxies are thought to be low on cold gas, an important raw material for star forming, but a new study in the Monthly Notices of the Royal...

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...
