Light from huge explosion 12 billion years ago reaches Earth

Posted: 04 Jun 2014 07:55 AM PDT

Intense light from the enormous explosion of a star 12.1 billion years ago -- shortly after the Big Bang -- recently reached Earth and was observed by a robotic telescope. Known as a gamma-ray burst, these rare, high-energy explosions are the catastrophic collapse of a star at the end of its life. Astronomers can analyze the observational data to draw further conclusions about the structure of the early universe.

Black hole 'batteries' keep blazars going and going

Astronomers studying two classes of black-hole-powered galaxies have found evidence that they represent different sides of the same cosmic coin. By unraveling how these objects, called blazars, are distributed throughout the universe, the scientists suggest that apparently distinctive properties defining each class more likely reflect a change in the way the galaxies extract energy from their central black holes.

Investigating unusual three-ribbon solar flares with extreme high resolution

The 1.6 meter telescope at Big Bear Solar Observatory in California has given researchers unparalleled capability for investigating phenomena such as solar flares. The BBSO instrument is the most powerful ground-based telescope dedicated to studying the star closest to Earth.

Violent, complex scene of colliding galaxy clusters

Astronomers have viewed a fascinating, complex scene where clusters of galaxies are violently colliding. Observations show a complex region more than 5 billion light-years from Earth where the collisions are triggering a host of phenomena that scientists still are working to understand.
