Supernova Dust Factory
2014-01-06 12:08:48

[ Watch the Video: Supernovas May Be Galactic Dust Factories ] Lee Rannals for redOrbit.com - Your Universe Online A new image of a recent supernova could offer up insight to scientists about how galaxies became so dusty. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have observed the remains of supernova 1987A located in the Large Magellanic Cloud about 168,000 light-years from Earth. This is the closest observed supernova explosion since Johannes...

Astronomers Search For Cause Of Massive Star Formation
2013-12-21 04:25:12

redOrbit Staff & Wire Reports - Your Universe Online In an attempt to determine why massive stars – those with at least eight times the mass of our Sun – grow so much larger than most other stars in our galaxy, astronomers used the ALMA telescope to examine the cores of Infrared Dark Clouds roughly 10,000 light-years away. Infrared Dark Clouds are located in the direction of the constellations of Aquila and Scutum, and they are among the darkest, densest and coldest clouds in...

Urban Galactic Clusters Stopped Forming Stars Billions Of Years Ago
2013-12-19 12:36:09

Brett Smith for redOrbit.com - Your Universe Online A new study based on data from NASA’s Spitzer Space Telescope has revealed new details about so-called urban galaxies that exist in large clusters. The study found that these clusters stopped forming new stars about 9 billion years ago, much later than previously thought. These galactic cities were said to have eventually either used up or lost their fuel. Meanwhile, more rural galaxies are still actively forming stars. "We know...

Study Of Massive Stars Shows Milky Way's Missing Arms
2013-12-17 08:54:09

University of Leeds A 12-year study of massive stars has reaffirmed that our Galaxy has four spiral arms, following years of debate sparked by images taken by NASA's Spitzer Space Telescope that only showed two arms. The new research, which is published online today [17 December] in the Monthly Notices of the Royal Astronomical Society, is part of the RMS Survey, which was launched by academics at the University of Leeds. Astronomers cannot see what our Galaxy, which is called the...

Spitzer's Citizen Science Zoo Displays New Animals
2013-12-17 08:17:13

NASA's Jet Propulsion Laboratory Since 2010, about 50,000 volunteers have taken to their computers to help astronomers catalog star-blown bubbles captured in images from NASA's Spitzer Space Telescope. Their efforts resulted in several scientific papers, and a deeper understanding of our Milky Way galaxy and its frothy star-forming clouds. Now, an updated version of the campaign, called the Milky Way Project, is releasing more images with a whole new set of "animals" to track in the...

Mysterious Radio Bursts May Originate From Nearby Flaring Stars
2013-12-13 04:17:34

redOrbit Staff & Wire Reports - Your Universe Online Extremely quick, extremely bright radio pulses known as “fast radio bursts” may originate from flaring stars located within our own galaxy, researchers from the Harvard-Smithsonian Center for Astrophysics (CfA) claim in a new study. Based on their characteristics, scientists had believed that these radio bursts came from galaxies located billions of light-years away. However, the pulses – which typically only last for...

Starburst Galaxy M82 - An Up Close And Personal Look
2013-12-10 04:23:24

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have managed to get an up close and personal look at the nearby starburst galaxy M82, detecting concentrations of dense molecular gas surrounding regions of intense star formation and streams of material exiting the galaxy’s disk, the National Radio Astronomy Observatory (NRAO) announced Monday. The new data comes courtesy of the high-frequency Robert C. Byrd Green Bank Telescope (GBT), the world's largest,...

More Than Half A Million Galaxies Identified And Classified By The ALHAMBRA Project
2013-12-02 12:15:47

RUVID The ALHAMBRA project, led by researchers from the Instituto de Astrofísica de Andalucía and in which the University of Valencia has participated, has identified and classified more than half a million galaxies, after seven years of close observation of the universe from the Observatory of Calar Alto (CAHA, Almería) and thanks to a technique that breaks the stars energy in their colors through astronomical filters. In addition, this research has also allowed calculating the...

Milky Way Seen More Clearly Than Ever Thanks To New 3D Map Of The Stars
2013-11-29 04:10:22

Alan McStravick for redOrbit.com - Your Universe Online The Milky Way galaxy recently got a little easier to understand. A group of astronomers created a new 3D map of the stars that reside in the center of the Milky Way which shows, more clearly than ever, the bulge located at the core of our galaxy. Prior to this new representation it was widely believed the stars in the core orbited in a sort of banana shape. However, scientists, publishing this week in the journal Monthly Notices of...

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
