Record-Shattering, Ultra-Luminous Hypernova Explosion Stuns Astronomers, Poses New Cosmic Mystery

An artist’s impression of the record-breakingly powerful, superluminous supernova ASASSN-15lh that was recently discovered by the Automated Survey for SuperNovae (ASAS-SN), as it would appear from a hypothetical exoplanet located about 10,000 light years away in the host galaxy of the hypernova.

Type Ia supernova explosions can be considered as some of the Universe’s most spectacular and inviting attractions, signifying the death of very massive stars. With peak […]

Chandra X-Ray Observatory Helps Astronomers Weigh Most Massive Galaxy Cluster Discovered to Date

A composite, multi-wavelength image of the young galaxy cluster XDCP J0044.0-2033, also known as the Gioiello Cluster, which is located 9.6 billion light-years away. In the image, X-ray wavelengths appear purple, infrared appear as large red halos around some galaxies, and visible light appears as are red, green, and blue. Image Credit: X-ray: […]

Where's the Kaboom? Astronomers Detect No X-Ray Emission From Recent Supernova Explosion

The supernova SN 2014J, as imaged by NASA’s Chandra X-ray Observatory. This image contains Chandra data, where low-, medium-, and high-energy X-rays are red, green, and blue respectively. The boxes in the bottom of the image show close-up views of the region around the supernova in data taken prior to the explosion (left), […]

NASA Realigns Red Planet Armada to Reap Science Bonanza During Upcoming Comet Flyby and Protect Priceless Probes

This graphic depicts the orbit of comet C/2013 A1 Siding Spring as it swings around the Sun in 2014. On Oct. 19, 2014, the comet will have a very close pass at Mars. Its nucleus will miss Mars by about 82,000 miles (132,000 kilometers). Credit: NASA/JPL-Caltech
