Latest Starburst galaxy Stories
WASHINGTON, June 30, 2011 /PRNewswire-USNewswire/ -- Galaxies once thought of as voracious tigers are more like grazing cows, according to a new study using NASA's Spitzer Space Telescope. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Astronomers have discovered that galaxies in the distant universe continuously ingested their star-making fuel over long periods of time.
Galaxies are thought to develop by the gravitational attraction between and merger of smaller 'sub-galaxies', a process that standard cosmological ideas suggest should be ongoing.
An unusual galaxy with gas jets could explain how starforming galaxies become red and dead.
Elliptical galaxies were once thought to be aging star cities whose star-making heyday was billions of years ago.
The Sculptor galaxy is shown in different infrared hues, in this new mosaic from NASA's Wide-field Infrared Survey Explorer, or WISE.
The galaxy NGC 4666 takes pride of place at the center of this new image, made in visible light with the Wide Field Imager on the MPG/ESO telescope at the La Silla Observatory in Chile.
A spectacular new image of the Sculptor Galaxy (NGC 253) has been taken with the ESO VISTA telescope at the Paranal Observatory in Chile as part of one of its first major observational campaigns.
Scientists at the Naval Research Laboratory have solved a long-standing dilemma about the mass of infrared bright merging galaxies.
Radio astronomers at the University of Manchesterâ€™s Jodrell Bank Observatory have discovered a strange new object in a nearby galaxy.
University of Arizona astronomers have helped solve a mystery surrounding the birth of stars in galaxies that has long puzzled scientists.
Irregular Galaxy -- In astronomy, a class of galaxy with little structure, which does not conform to any of the standard shapes in the Hubble classification. The two satellite galaxies of the Milky Way, the Magellanic Clouds, are both irregulars. Some galaxies previously classified as irregulars are now known to be normal galaxies distorted by tidal effects or undergoing bursts of star formation (see starburst galaxy). ----- NASA Click here to learn more on this topic from...
Active Galaxy -- An active galaxy is a galaxy where a significant fraction of the energy output is not emitted from normal stellar populations or interstellar gas. This energy, depending on the active galaxy type, can be emitted across most of the electromagnetic spectrum, as infrared, radio waves, UV, X-ray and gamma rays. Frequently, the abbreviation AGN (Active Galactic Nuclei) is used, since most of the active galaxies emit most of their radiation from a narrow region in their...
