University of Maryland and NASA astronomers used rhythmic flares of light to measure a brilliant object 12 million light years from Earth, confirming that it is a rare, mysterious intermediate-mass black hole. (PRWEB) August 17, 2014 The universe has so many black holes that it’s impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big, and colossal. Astronomers know that black...

redOrbit Staff & Wire Reports - Your Universe Online Seven rare and microscopic particles of space dust collected by instruments onboard NASA’s Stardust mission could be the first samples of contemporary interstellar dust ever obtained by scientists, an international team of researchers report in Friday’s edition of the journal Science. The samples, which were gathered by Stardust’s aerogel and aluminum foil dust collectors, likely originated from outside of our solar system....

Arecibo gas bridge
2014-08-08 06:43:44

Royal Astronomical Society Astronomers and students have found a bridge of atomic hydrogen gas 2.6 million light years long between galaxies 500 million light years away. They detected the gas using the William E. Gordon Telescope at the Arecibo Observatory, a radio astronomy facility of the US National Science Foundation sited in Puerto Rico. The team published their results Thursday in a paper in Monthly Notices of the Royal Astronomical Society. The stream of atomic hydrogen gas is...

Messier 33
2014-08-06 11:14:16

ESO Messier 33, otherwise known as NGC 598, is located about three million light-years away in the small northern constellation of Triangulum (The Triangle). Often known as the Triangulum Galaxy it was observed by the French comet hunter Charles Messier in August 1764, who listed it as number 33 in his famous list of prominent nebulae and star clusters. However, he was not the first to record the spiral galaxy; it was probably first documented by the Sicilian astronomer Giovanni Battista...

April Flowers for redOrbit.com - Your Universe Online The Hubble Space Telescope is a joint project between NASA and the European Space Agency (ESA) that launched in 1990. Since then, it has returned thousands of images from its orbital position above the atmosphere, helping scientists to shed light on some of the mysteries of the cosmos. Hubble images prove that there is more to a galaxy than what first meets the eye. The telescope is able to look beyond the bright glow of a galaxy's...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online While images of the Milky Way or Andromeda galaxies may dominate our mind’s image of what a galaxy looks like, the fact is that the largest objects in the Universe come in all shapes and sizes. In fact, most galaxies in the cosmos are known as dwarf galaxies. These systems are, as the name might suggest, smaller versions of the elliptical, spiral, and irregular galaxies that usually spring to mind. In many cases, these...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online As astronomers have sought to understand the formation and evolution of galaxies, a handful of simple truths have emerged. Despite many questions remaining, we know that galaxies form in clusters, and create interlinked chains and structures that create a spider web across the cosmos. [ Watch the Video: Hubblecast 76: Merging Galaxies And Droplets Of Starbirth ] Because they often move through the Universe in such close...

Distant Galaxy Shows Evidence Of A 'Red And Dead' Future
2014-07-10 13:45:41

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online When galaxies first form they are dominated by gas that, over time, lays the foundation for stars. As more stars form the gas becomes locked up in stellar objects and their core remnants, such as white dwarfs, neutron stars, and black holes. Eventually, the gas will become depleted, leaving behind a cold dead galaxy. This process, however, can look different for varying galaxy types, and astronomers have been looking to...

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 NGC 5866, located in the Draco constellation, is named after the galaxy with the highest magnitude however some catalogs list NGC 5907 as the brightest member. The M51 Group and the M101 Group are NGC 5866 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 separate.

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...
