WASHINGTON, Sept. 24, 2013 /PRNewswire-USNewswire/ -- Astronomers using NASA's Hubble Space Telescope and Chandra X-ray Observatory and telescopes on the ground may have found the most crowded galaxy in our part of the universe. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The ultra-compact dwarf galaxy, known as M60-UCD1, is packed with an extraordinary number of stars and may be the densest galaxy near Earth. It is providing astronomers with clues to its...

Densest Galaxy Discovered

[ Watch the Video: Hubble Locates Densest Galaxy Ever ] Brett Smith for redOrbit.com - Your Universe Online The distance from our sun to the next closest star, Alpha Centauri, is 25.6 trillion miles. While that may seem far, try to imagine 10,000 stars sitting between the two solar systems, meaning the stars would be spaced about the distance from Earth to Pluto. That’s exactly the scenario in M60-UCD1, a recently discovered 'ultra-compact dwarf galaxy' described in a study by a...

Milky Way In 3D

John P. Millis, PhD for redOrbit.com - Your Universe Online Because of our location within the Milky Way, it is quite a challenge to get a bird’s eye view of our galaxy. To really get a sense for what our corner of the cosmos really looks like, astronomers have to take detailed measurements of billions of stars and attempt to accurately measure their distance from Earth. Researchers at the Max Planck Institute for Extraterrestrial Physics (MPE) have now created the most detailed model...

Astronomers Find Peanut Sitting In Middle Of Milky Way

[ Watch the Video: Artist's Impression Of The Milky Way ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers, publishing two papers in the journal Astronomy & Astrophysics, say they've found a peanut sitting in the heart of the Milky Way galaxy. Two teams used data from European Southern Observatory (ESO) telescopes to create a three-dimensional map of the central parts of the Milky Way. While crafting the map they found that the inner regions of the galaxy take on a...

Generation Gap In Stars' Orbital Dance

[ Watch the Video: Zoom into 47 Tucanae ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using NASA's Hubble Space Telescope are tracking the orbital motion of 33,000 stars in one of the Milky Way's oldest globular clusters. The team will be using the space observatory to track the orbital motion of 33,000 stars within globular cluster 47 Tucanae, which sits over 16,000 light-years away from Earth. "When analyzing the motions of stars, the longer the time baseline...

[ Watch the Video: Simulation of Gas Cloud Being Ripped Apart By Black Hole ] Lee Rannals for redOrbit.com - Your Universe Online The European Southern Observatory's (ESO) Very Large Telescope (VLT) has helped astronomers catch a supermassive black hole ripping apart a gas cloud for the first time. Astronomers writing in the Astrophysical Journal say the gas cloud being ripped apart by the Milky Way's supermassive black hole is now so stretched that its front portion has passed the...

WASHINGTON, June 3, 2013 /PRNewswire-USNewswire/ -- Astronomers at NASA and Pennsylvania State University have used NASA's Swift satellite to create the most detailed ultraviolet light surveys ever of the Large and Small Magellanic Clouds, the two closest major galaxies. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) "We took thousands of images and assembled them into seamless portraits of the main body of each galaxy, resulting in the highest-resolution surveys of the...

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...

Milky Way Galaxy -- The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia (gala, galactos means "milk")) is a hazy band of white light across the night sky formed by billions of stars in the disc of our galaxy. The Milky Way appears brightest in the direction of Sagittarius, where the galactic centre lies. Relative to the celestial equator, the Milky Way passes as far north as the constellation of Cassiopeia and as far south as the constellation of...
