Latest Starburst galaxy Stories
Dust plays an extremely important role in the universe - both in the formation of planets and new stars. But dust was not there from the beginning and the earliest galaxies had no dust, only gas. Now an international team of astronomers, led by researchers from the Niels Bohr Institute, has discovered a dust-filled galaxy from the very early universe. The discovery demonstrates that galaxies were very quickly enriched with dust particles containing elements such as carbon and oxygen, which...
Starburst galaxies transmute gas into new stars at a dizzying pace - up to 1,000 times faster than typical spiral galaxies like the Milky Way. To help understand why some galaxies "burst" while others do not, an international team of astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to dissect a cluster of star-forming clouds at the heart of NGC 253, one of the nearest starburst galaxies to the Milky Way.
Nestled among a triplet of young galaxies more than 12.5 billion light-years away is a cosmic powerhouse: a galaxy that is producing stars nearly 1,000 times faster than our own Milky Way.
By measuring the radiation leaks in a large, densely-packed star-forming galaxy, astronomers have been able to learn more about how the universe evolved as the first stars were formed, according to research published online Thursday in the journal Science.
Using a battery of observatories that included the ALMA and the Hubble Space Telescope, astronomers have obtained the best view to date of a collision between two galaxies that took place when the universe was just a fraction of its current age.
They may be little, but they pack a big star-forming punch. New observations from NASA's Hubble Space Telescope show small galaxies, also known as dwarf galaxies, are responsible for forming a large proportion of the universe's stars.
WASHINGTON, June 19, 2014 /PRNewswire-USNewswire/ -- They may be little, but they pack a big star-forming punch.
Astronomers writing in the Astrophysical Journal say that massive galaxies in the early universe were formed through collisions.
A faint river of hydrogen has been discovered to be flowing through space, filtering into a nearby galaxy known as NGC 6946. The discovery could lead to a better understanding of how some galaxies maintain star formation.
After years of active participating by the public – and a host of interesting discoveries by amateur astronomers and enthusiasts – the Galaxy Zoo project is releasing its first scientific finding to come out of the data.
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...
