NASA sees 'watershed' cosmic blast in unique detail

On April 27, a blast of light from a dying star in a distant galaxy became the focus of astronomers around the world. The explosion, known as a gamma-ray burst and designated GRB 130427A, tops the charts as one of the brightest ever seen. A trio of NASA satellites, working in concert with ground-based robotic telescopes, captured never-before-seen details that challenge current theoretical understandings of how gamma-ray bursts work.

Racing particles from space

For the first time scientists have uncovered concrete evidence for highly energetic neutrinos stemming from outside our solar system. The IceCube experiment, a huge neutrino detector in Antarctica, has observed 28 neutrinos that most likely stem from cosmic objects such as supernovae, black holes, pulsars or other extreme cosmic phenomena.

NASA's Chandra helps confirm evidence of jet in Milky Way's black hole

Astronomers have long sought strong evidence that Sagittarius A*, the supermassive black hole at the center of the Milky Way, is producing a jet of high-energy particles. Finally they have found it, in new results from NASA's Chandra X-ray Observatory and the National Science Foundation's Very Large Array radio telescope.

Researchers simulate electrons in astrophysical plasma jets

Physicists have been able to simulate the motion of billions of electrons within astrophysical plasma jets and calculate the light they emit with the help of a high-performance computer. They have been nominated for the Gordon Bell Prize as a result of their work.

Evidence found for granite on Mars

Researchers now have stronger evidence of granite on Mars and a new theory for how the granite - an igneous rock common on Earth - could have formed there, according to a new study. The findings suggest a much more geologically complex Mars than previously believed.
