Astronomers weigh 200-million-year-old baby galaxies

10-25-2006 · EurekAlert!

Astronomers have taken amazing pictures of two of the most distant galaxies ever seen. The ultradeep images, taken at infrared wavelengths, confirm for the first time that these celestial cherubs are real. The researchers are now able to weigh galaxies and determine their age at earlier times than ever before, providing important clues about the evolutionary origins of galaxies like our Milky Way.

Baby booms and birth control in space
09-25-2007 · EurekAlert!
Stars in galaxies are a bit similar to people: during the first phase of their existence they grow rapidly, after which a stellar birth control occurs in most galaxies. Thanks to new observations from Dutch astronomer Mariska Kriek with the Gemini Telescope on Hawaii and the Very Large Telescope in Chile, it is now known that a part of the heavy galaxies already stopped forming stars when the universe was still a toddler, about three billion years old.

Hubble shows 'baby' galaxy is not so young after all
10-16-2007 · EurekAlert!
The NASA/ESA Hubble Space Telescope has found out the true nature of a dwarf galaxy that astronomers had for a long time identified as one of the youngest galaxies in the Universe. Astronomers using the NASA/ESA Hubble Space Telescope have made observations of the galaxy I Zwicky 18 which seem to indicate that it is in fact much older and much farther away than previously thought.

Double-star systems cycle between big and small blasts
03-07-2007 · EurekAlert!
Certain double, or binary, star systems erupt in full-blown explosions and then flare up with smaller bursts, according to new information gathered by NASA’s Galaxy Evolution Explorer (GALEX) and analyzed by a team of astronomers, including postdoctoral researcher Mark Seibert of the Carnegie Observatories. The data bolster a 20-year-old theory suggesting that double star systems experience both explosion types, rather than just one or the other.

New technology enables astronomers to detect two supermassive black holes in colliding galaxies
05-17-2007 · EurekAlert!
Astronomers, including UCR’s Gabriela Canalizo, have used powerful adaptive optics technology at the W.M. Keck Observatory in Hawai‘i to reveal the precise locations and environments of a pair of supermassive black holes at the center of an ongoing collision between two galaxies 300 million light-years away. Each of the black holes resides at the center of a rotating disk of stars and is surrounded by a cloud of young star clusters formed in the merger.

Hubble finds strong contender for galaxy distance record
02-12-2008 · EurekAlert!
The NASA/ESA Hubble Space Telescope, with a boost from a natural "zoom lens," has found the strongest evidence so far for a galaxy with a redshift significantly above 7. It is likely to be one of the youngest and brightest galaxies ever seen right after the cosmic "dark ages," just 700 million years after the beginning of our universe (redshift ~7.6).
