Gamma Ray Bursts - Death Rays from Space Gamma Ray Bursts (GRBs) are one of the Most Brightest and Energetic Events in the Universe. The Source of Gamma Ray Bursts include Supernova Explosion of a High Mass Star, Collision of 2 Neutron Stars, or even Formation of a Black hole. GRBs can last upto ten milliseconds (or even several hours). Even in this short time, GRBs release huge amounts of Energy. In fact, GRBs can release more energy in some seconds than Sun in it's 10 Billion Year lifetime. |

Westerlund 1 • Fermi Spots Young Star Cluster Blowing Gamma-Ray Bubbles • 19.12.25 VIDEO: This image of super star cluster Westerlund 1 was captured with the Near-InfraRed Camera on NASA’s James Webb’s Space Telescope. The cluster is largely hidden at visible wavelengths by dust clouds, which infrared light penetrates. Westerlund 1’s large, dense, and diverse stellar population of massive stars has no other known counterpart in the Milky Way. Credit: ESA/Webb, NASA & CSA • For the first time, as

• Astronomers Spot Mysterious Gamma-ray Explosion, Unlike Any Detected Before 11.9.25 VIDEO: This sequence of images shows the evolution over several days of the gamma-ray burst GRB 250702B. This GRB was first observed with high-energy telescopes on 2 July, which detected several flares of gamma rays over the course of a day. [ESO/A. Levan, A. Martin-Carrillo et al.] • Astronomers have detected an explosion of gamma rays that repeated several times over the course of a day, an event unlike anyth
