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), as […]

The Improbable Case of the High-Energy Novae: NASA's Fermi Space Telescope Detects New Gamma Ray Sources

Novae typically originate in binary systems containing Sun-like stars, as shown in this artist’s rendering. NASA’s Fermi Space Telescope discovered that a nova in a system like this likely produces gamma rays (magenta) through collisions among multiple shock waves in the rapidly expanding shell of debris.
