Hubble sees the graceful dance of 2 interacting galaxies
A pair of galaxies, known collectively as Arp 87, is one of hundreds of interacting and merging galaxies known in our nearby Universe. Arp 87 was originally discovered and catalogued by astronomer Halton Arp in the 1970s. Arp's Atlas of Peculiar Galaxies is a compilation of astronomical photographs using the Palomar 200-inch Hale and the 48-inch Samuel Oschin telescopes. View News Article (2007-10-31)


'Red nugget' galaxies were hiding in plain sight
In 2005 the Hubble Space Telescope spotted unusually small galaxies densely packed with red stars in the distant, young universe. They were nicknamed "red nuggets," not only because they are small and red but also their existence challenged current theories of galaxy formation, making them precious in astronomers' eyes. View News Article (2013-09-16)


Largest ever survey of very distant galaxy clusters completed
An international team of researchers led by a UC Riverside astronomer has completed the largest ever survey designed to find very distant clusters of galaxies. View News Article (2009-07-01)


Hubble and Spitzer Space Telescopes find 'Lego-block' galaxies in early universe
The conventional model for galaxy evolution predicts that small galaxies in the early Universe evolved into the massive galaxies of today by coalescing. Nine Lego-like "building block" galaxies initially detected by Hubble likely contributed to the construction of the Universe as we know it. View News Article (2007-09-07)


Cause of galactic death: Strangulation
As murder mysteries go, it's a big one: how do galaxies die and what kills them? A new study, published today in the journal Nature, has found that the primary cause of galactic death is strangulation, which occurs after galaxies are cut off from the raw materials needed to make new stars.  View News Article (2015-05-13)


Galaxies are running out of gas
The Universe forms fewer stars than it used to, and a CSIRO study has now shown why - the galaxies are running out of gas. View News Article (2011-08-23)


There's more star-stuff out there but it's not Dark Matter
More atomic hydrogen gas - the ultimate fuel for stars - is lurking in today's Universe than we thought, CSIRO astronomer Dr Robert Braun has found. View News Article (2012-05-31)


Queen's physicist unlocking the mysteries of neighbouring galaxies
An international team of astronomers, including Queen's University physicist Larry Widrow, have uncovered evidence of a nearby cosmic encounter. View News Article (2009-09-08)


Green Pea galaxies could help astronomers understand early universe
The rare Green Pea galaxies discovered by the general public in 2007 could help confirm astronomers' understanding of reionization, a pivotal stage in the evolution of the early universe, say University of Michigan researchers. View News Article (2013-04-04)


NASA'S Chandra finds black holes stirring up galaxies
Black holes are creating havoc in unsuspected places, according to a new study of images of elliptical galaxies made by NASA's Chandra X-ray Observatory. View News Article (2006-01-11)
