It sounds like something from a bad sci-fi movie, but a NASA space telescope has detected what might be the X-ray “screams” from dead (zombie) stars. The […]

New Research Suggests Potential Link Between Neutrinos and the Supermassive Black Hole at Milky Way's Center

An unprecedented view of the black hole at the center of the Milky Way Galaxy, known as Sagittarius A*, that was obtained with NASA’s Chandra X-ray Observatory. A new study has provided evidence that Sagittarius A* is a source of high-energy neutrinos. Image Credit: NASA/CXC/Univ. of Wisconsin/Y.Bai. et al.

Cosmic Ray Hit Causes Small Delay at Dawn's Rendezvous With Ceres Early Next Year

An artist’s concept of NASA’s Dawn spacecraft exploring Vesta and Ceres in the asteroid belt between Mars and Jupiter. Dawn had recently experienced an anomaly in its ion propulsion system resulting from a cosmic ray hit, which will cause a small delay to the spacecraft’s rendezvous with Ceres next year.

Hunting In the Dark: New Results Come From Alpha Magnetic Spectrometer on ISS, But No Definite Signs of Dark Matter Yet

The Alpha Magnetic Spectrometer is seen here at center left, following its installation on the S3 Truss on the International Space Station by the crew of the STS-134 space shuttle mission in 2011. The orbiting particle detector has been continuously collecting data ever since, on high-energy cosmic rays. Image Credit: NASA
