Galaxy’s Rings Help Astronomers Unveil Its Past
2013-10-31 16:40:49

Lee Rannals for redOrbit.com – Your Universe Online Similar to reading tree rings, astronomers are able to read the rings in a galaxy’s disk to help gain a better understanding of its past. Scientists using NASA's Wide-field Infrared Survey Explorer (WISE) and Galaxy Evolution Explorer (GALEX) have gained evidence supporting the “inside-out” theory of galaxy growth, which says that formation starts with the bursts of star formation. "Initially, a rapid star-forming period...

Astronomers Catch Supermassive Black Hole Devouring Distant Star
2012-05-02 14:24:52

Lawrence LeBlond for RedOrbit.com [ Watch the Video ] Astronomers have for the very first time captured a supermassive black hole devouring a wandering star that strayed too close to a phenomena that nothing can escape, not even light. Although the star most likely met its demise in an untimely fashion, it is an extraordinary event for science and astronomy, as scientists believe it may provide them with greater clues on the inner workings of dark behemoths nestled away in the hearts...
