Unraveling Galactic History Begins With A Black Hole's Spin
2013-07-30 14:11:38

Brett Smith for redOrbit.com - Your Universe Online A supermassive black hole is believed to sit at the center of each large galaxy, and a new technique designed to detect the dark abyss' spin could be the key to unraveling a galaxy's history. While black holes cannot be seen directly, their behavior can be determined by looking at how they affect nearby objects. A paper published in Monthly Notices of the Royal Astronomical Society describes a new technique that was developed by...

WIYN Telescope Captures Highly Detailed Whirlpool Galaxy Image
2013-07-26 18:40:41

Brett Smith for redOrbit.com - Your Universe Online Astronomers have been observing the Whirlpool Galaxy since the 18th century, but they've never seen it like this. A new One Degree Imager (ODI) camera at the Kitt Peak National Observatory in Arizona has captured stunning new images of the distant spiral galaxy in never-before-seen detail. When used with the WIYN 3.5-meter telescope at the observatory, the camera is able to provide images of the Whirlpool Galaxy and its companion...

Earth's Neighborhood In The Milky Way Sits On Spiral Arm, Not Spur
2013-06-03 14:49:23

Lee Rannals for redOrbit.com — Your Universe Online New research using the ultra-sharp radio vision of the National Science Foundation's (NSF) Very Long Baseline Array (VLBA) has determined that we live in a more upscale neighborhood in our galaxy than previously thought. Considering we reside inside the Milky Way, it is tough for scientists to predict exactly where in our galaxy we sit. Astronomers are able to get a bird's-eye view of other galaxies, but we must use different...

Cold Gas May Fuel Galaxy And Star Formation
2013-05-26 05:49:55

redOrbit Staff & Wire Reports - Your Universe Online As galaxies grow over the course of billions of years, they apparently use the cosmic equivalent of bendy straws to feed on cold gas and gain mass, according to new research published in the May 20 edition of the Astrophysical Journal. The study is based on computer simulations conducted by Kyle Stewart, who is currently with California Baptist University in Riverside but completed most of the research while with NASA´s Jet...

Halo Clouds Spotted Around Colliding Galaxies
2013-05-01 05:19:26

April Flowers for redOrbit.com - Your Universe Online A detailed study of an enormous cloud of hot gas that envelops two large, colliding galaxies has been made using NASA´s Chandra X-ray Observatory. This oversized gas reservoir contains as much mass as 10 billion Suns, is 300,000 light years across, and radiates more than 7 million degrees Kelvin. Scientists call this sort of cloud a “halo.” This particular halo is located in the system designated NGC 6240, which...

Starburst Galaxies Observations Reveal They Occured Earlier In Universe Than Previously Believed
2013-03-13 14:29:45

WATCH VIDEO: [Gravitational Lensing of Distant Star-Forming Galaxies] Lee Rannals for redOrbit.com — Your Universe Online Astronomers reported in Nature and the Astrophysical Journal that starburst galaxies from early in the universe's history took place earlier than previously though. Scientists making observations with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope say they have found that the most vigorous bursts of star birth in the universe actually took...

Hubble Tuning Fork Interactive Diagram
2012-11-19 13:27:53

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) released an image this week of an interactive diagram known as the Hubble Tuning Fork. The diagram helps to describe the shape of galaxies, which can come in all different sizes. It ranges between elliptical galaxies, intermediate spirals, barred spirals and irregular shapes. The interactive map gives the examples of the different shapes of the galaxies, as well as a description in type, morphology,...

The Local Universe Offered Up In Unprecedented Detail
2012-10-31 13:21:28

Lee Rannals for redOrbit.com - Your Universe Online The intimate details of 100 galaxies in the local universe have been published by the Calar Alto Legacy Integral Field Area survey (CALIFA). The survey offers up new data, representing the first large-scale effort at "two plus one" mapping of galaxies. For every pixel within each two-dimensional image, scientists could perform a detailed analysis and provide information about dynamics and chemical composition. This information could...

Chandra Eyes Mini Supermassive Black Hole
2012-10-25 07:19:58

April Flowers for redOrbit.com - Your Universe Online NASA's Chandra X-ray Observatory, along with other observatories, has identified one of the lowest mass supermassive black holes ever observed in the middle of a galaxy that one would not expect to harbor this type of beast. This suggests that this black hole, while related to its supermassive cousins, may have a different origin. Located in the middle of the spiral galaxy NGC 4178, the black hole is shown in the image from the Sloan...

Distant Quasar Shows No Sign Of Feeding On Galaxy Of Stars
2012-10-24 12:05:36

Lee Rannals for redOrbit.com — Your Universe Online While looking at one of the most distant quasars in the universe, astronomers were surprised to not see an underlying host galaxy of stars feeding it. NASA said the best explanation is that the galaxy is shrouded in so much dust that the stars are completely hidden everywhere. As stars aged and burned out in the early universe, they filled interstellar space with dust as they lost their atmosphere. The quasar dates back to an...

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....

Elliptical Galaxy -- In astronomy, one of the main classes of galaxy in the Hubble classification and characterized by a featureless elliptical profile. Unlike spiral galaxies, elliptical galaxies have very little gas or dust and no stars have recently formed within them. They range greatly in size from giant ellipticals, which are often found at the centres of clusters of galaxies and may be strong radio sources, to tiny dwarf ellipticals, containing about a million stars, which are...
