Provided by Felicia Chou, NASA Headquarters Peering through a giant cosmic magnifying glass, NASA’s Hubble Space Telescope has spotted a tiny, faint galaxy -- one of the farthest galaxies ever seen. The diminutive object is estimated to be more than 13 billion light-years away. This galaxy offers a peek back to the very early formative years of the universe and may just be the tip of the iceberg. “This galaxy is an example of what is suspected to be an abundant, underlying...

Provided by Julie Cohen, UC Santa Barbara UCSB astrophysicist uses data gathered by a Russian spacecraft to bring science one step closer to figuring out the mysteries of our galaxy’s core Is matter falling into the massive black hole at the center of the Milky Way or being ejected from it? No one knows for sure, but a UC Santa Barbara astrophysicist is searching for an answer. Carl Gwinn, a professor in UCSB’s Department of Physics, and colleagues have analyzed images collected...

Chuck Bednar for redOrbit.com - Your Universe Online By measuring the radiation leaks in a large, densely-packed star-forming galaxy, astronomers have been able to learn more about how the universe evolved as the first stars were formed, according to research published online Thursday in the journal Science. Lead author Sanchayeeta Borthakur, an assistant research scientist at Johns Hopkins University, and her colleagues reported how they used a method of analyzing star-forming galaxies...

Brett Smith for redOrbit.com - Your Universe Online A team of Australian astrophysicists has determined that the Milky Way has half as much dark matter as previously thought, according to a new study published in the Astrophysical Journal. Dark matter is a mysterious invisible substance that has profound gravitational effect throughout the universe. The researchers found that the amount of dark matter in our galaxy is 800,000,000,000 times the mass of the Sun. To reach their...

Georgia Bladon, Hubble/ESA Astronomers usually have to peer very far into the distance to see back in time, and view the Universe as it was when it was young. This new NASA/ESA Hubble Space Telescope image of galaxy DDO 68, otherwise known as UGC 5340, was thought to offer an exception. This ragged collection of stars and gas clouds looks at first glance like a recently-formed galaxy in our own cosmic neighborhood. But, is it really as young as it looks? Astronomers have studied...

ESO New observations explain why Milky Way-like galaxies are so common in the Universe An international research group led by Junko Ueda, a Japan Society for the Promotion of Science postdoctoral fellow, has made surprising observations that most galaxy collisions in the nearby Universe — within 40 million light-years from Earth — result in so-called disc galaxies. Disc galaxies — including spiral galaxies like the Milky Way and lenticular galaxies — are defined by...

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...
