WATCH VIDEOS: [Animation of a Starburst Galaxy] | [Probing a Galactic Halo] Lee Rannals for redOrbit.com – Your Universe Online Astronomers writing in The Astrophysical Journal say they've observed how bursts of star formation have a major impact beyond the boundaries of their host galaxy. When galaxies form new stars, they can create frantic episodes of activity known as starbursts. Scientists using the Hubble Space Telescope say these events can affect galactic gas at distances...
Brett Smith for redOrbit.com – Your Universe Online Efficiency experts and green technology proponents can now look to the heavens for inspiration, as astronomers have identified a galaxy that forms stars at almost 100 percent efficiency. According to a new report in Astrophysical Journal Letters, telltale signs from NASA's Wide-field Infrared Survey Explorer (WISE), the Hubble Space Telescope and the Plateau de Bure interferometer at the Institut de Radioastronomie Millimétrique...
Lee Rannals for redOrbit.com - Your Universe Online Astronomers report in The Astrophysical Journal that they have determined the positions of over 100 of the most fertile star-forming galaxies in the early Universe. The group used the new Atacama Large Millimeter/submillimeter Array (ALMA) telescope during their observations. This telescope can capture just as many observations of this group of galaxies in just a few hours as similar telescopes can in more than a decade. [ Video:...
Brett Smith for redOrbit.com - Your Universe Online An international team of researchers announced it has found some of the Universe’s earliest starburst galaxies, essentially young energetic clusters of cosmic gas and dust that form stars at an alarming rate. The discoveries, which were detailed in reports published in Nature and the Astrophysical Journal, were made using the newly inaugurated Atacama Large Millimeter/submillimeter Array (ALMA) telescope. In its first billions...
WASHINGTON, Jan. 10, 2013 /PRNewswire-USNewswire/ -- The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil has crowned it the largest-known spiral, based on archival data from NASA's Galaxy Evolution Explorer (GALEX) mission. GALEX has since been loaned to the California Institute of Technology in Pasadena, Calif. (Logo:...
April Flowers for redOrbit.com - Your Universe Online A team of scientists conducting a long-term study of molecules in galaxies gained a tantalizing look at what is likely a powerful belch by a gorging black hole at the center of a changing galaxy. "The discovery was entirely serendipitous. Our observations were spread over a few years, and when we looked at them, we found that one galaxy had changed over that time from being placid and quiescent, to undergoing a hugely energetic...
[ Video 1 ] | [ Video 2 ] | [ Video 3 ] Lee Rannals for redOrbit.com - Your Universe Online A new Hubble Space Telescope image has been unveiled of NGC 922, revealing the cosmic structure to be an unusual spiral galaxy. The ring structure and distorted spiral shape of NGC 922 was imaged with NASA's Chandra X-ray Observatory to reveal even more chaos in the form of ultra luminous X-ray sources. The galaxy's unusual form is due to a cosmic bulls eye millions of years ago. A smaller...
[ Watch the Video: Hercules A Zoom Sequence ] Lee Rannals for redOrbit.com - Your Universe Online A new Hubble Space Telescope image released today shows off a multi-wavelength view of radio galaxy Hercules A. The image was produced through a collaboration of the Hubble Space Telescope's Wide Field Camera 3, and the upgraded Karl G. Jansky Very Large Array (VLA) radio telescope in New Mexico. The yellowish elliptical galaxy seen in the image is about 1,000 times more massive than...
April Flowers for redOrbit.com - Your Universe Online Many images that we see from the space observatories are beautiful. Swirling colors and bright galaxies make for amazing images. But an image just released from the ground-based Gemini Observatory of the polar-ring galaxy NGC 660 might be the most hauntingly beautiful image ever. Add in the back story of a colorful and dramatic tale of two galaxies locked in a life-and-death struggle, and the picture becomes poetry in motion. All...
Video: Panning Across Spiral Galaxy NGC 1187 | Video: Zooming In On Spiral Galaxy NGC 1187 April Flowers for redOrbit.com - Your Universe Online About 60 million light-years away, there is a beautiful, tranquil looking blue spiral galaxy named NGC 1187. This galaxy is in the constellation of Eridanus, or The River. Researchers at the European Southern Observatory (ESO) have been watching and recording data from NGC 1187 for about a year using the Very Large Telescope (VLT) at the La...

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...
Robert's Quartet is four different galaxies in the process of colliding and merging. The galaxies reside in the Phoenix constellation approximately 160 million light-years away. Its members are NGC 87, NGC 88, NGC 89 and NGC 92, discovered by John Herschel in the 1830s. The quartet is one of the best examples of compact groups of galaxies. Since such groups contain four to eight galaxies in a very small area, they provide great laboratories for the study of galactic interactions and their...
Spiral Galaxy -- Among the galaxies, there are apparently three main categories, according to their appearance: the disk galaxies (`cosmic frisbies' according to P. Murdin, D. Allen, and D. Malin), consisting of a huge disk of stars and interstellar matter, which may form interesting patterns, the elliptical galaxies (`cosmic footballs') which are uniformly looking, ellipsoidal agglomerations of stars, and the irregular galaxies (`cosmic misfits') which cannot be integrated in this scheme....
Seyfert's Sextet -- Seyfert's Sextet is a group of galaxies in which gravitational forces are exerted between its members. The galaxies are so tightly packed together that gravitational forces are beginning to rip stars from them and distort their shapes. Those same gravitational forces eventually could bring the galaxies together to form one large galaxy. The name of this grouping, Seyfert's Sextet, implies that six galaxies are participating in the action. But only four galaxies are...
Circinus Galaxy -- Resembling a swirling witch's cauldron of glowing vapors, the black hole-powered core of a nearby active galaxy appears in this colorful NASA Hubble Space Telescope image. The galaxy lies 13 million light-years away in the southern constellation Circinus. This galaxy is designated a type 2 Seyfert, a class of mostly spiral galaxies that have compact centers and are believed to contain massive black holes. Seyfert galaxies are themselves part of a larger class of objects...
