[WATCH VIDEO: Computer Model Shows a Disk Galaxy’s Life History] Lee Rannals for redOrbit.com – Your Universe Online After a comprehensive study of hundreds of galaxies, astronomers have uncovered a surprising trend in galaxy evolution. The team studied a sample of 544 blue galaxies from the Deep Extragalactic Evolutionary Probe 2 (DEEP2) Redshift Survey, and wrote about their findings in The Astrophysical Journal. "Astronomers thought disk galaxies in the nearby universe had...

WASHINGTON, Oct. 19, 2012 /PRNewswire-USNewswire/ -- A comprehensive study of hundreds of galaxies observed by the Keck telescopes in Hawaii and NASA's Hubble Space Telescope has revealed an unexpected pattern of change that extends back 8 billion years, or more than half the age of the universe.

UC Santa Cruz -- New findings from a large survey of galaxies suggest that star formation is largely driven by the supply of raw materials, rather than by galactic mergers that trigger sudden bursts of star formation. Stars form when clouds of gas and dust collapse under the force of gravity, and the study supports a scenario in which exhaustion of a galaxy's gas supply leads to a gradual decline in the star-formation rate. The results, presented this week at the American Astronomical Society...

Tampa, Fla. -- A fundamental number that affects the color of light emitted by atoms as well as all chemical interactions has not changed in more than 7 billion years, according to observations by a team of astronomers charting the evolution of galaxies and the universe. The results are being reported today (Monday, April 18) at the annual meeting of the American Physical Society (APS) by astronomer Jeffrey Newman, a Hubble Fellow at Lawrence Berkeley National Laboratory representing DEEP2, a...
