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.

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 […]

NuSTAR Sheds New Light on Supernova Explosions

This is the first map of radioactivity in a supernova remnant, the blown-out bits and pieces of a massive star that exploded. The blue color shows radioactive material mapped in high-energy X-rays using NuSTAR. Heated, non-radioactive elements previously imaged by Chandra using low-energy X-rays are shown in red, yellow, and green. Image Credit/Caption: […]

Chandra Telescope Observes Impressive Pulsar Racing Away From Ancient Supernova

An extraordinary jet trailing behind a runaway pulsar is seen in this composite image that contains data from Chandra (purple), radio data from the ACTA (green), and optical data from the 2MASS survey (red, green, and blue). The pulsar—a spinning neutron star—and its tail are found in the lower right of this image. […]

Hubble Breaks Record in Search for Farthest Supernova

Since its inaugural deployment from the shuttle in April 1990, the Hubble Space Telescope has peered deeper into the cosmos than ever before in human history. The recent discovery of Supernova SN Wilson—more than 10 billion years old—refines scientists’ yardstick for the age of the Universe. Photo Credit: NASA

More than two decades […]
