#Supernovae

The Epoch of Reionization is when radiation from early galaxies and their stars reionized neutral hydrogen and let light travel freely through the cosmos. Some research shows that supernovae helped the process.…

Strong gravitational lensing and microlensing of supernovae (SNe) are emerging as a new probe of cosmology and astrophysics in recent years. We provide an overview of this nascent research field, starting with a summary of the first discoveries of…

NASA’s Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova — one of the most extreme explosions in the universe.…

Every time an astronomer points a telescope at a distant supernova, they're trying to measure how far away it is. But the light from these stellar explosions arrives tangled up with interference from dust, the age of the host galaxy and the chemical make…

We've been waiting a long time for the Vera Rubin Observatory to begin its work. The observatory features the largest digital camera ever built. It'll create a time-lapse of the southern night sky for ten years with its 3.2 gigapixel camera.…
