An extraordinarily rare, gravitationally lensed supernova may offer a powerful new way to measure the universe’s expansion rate.
A burst of light in the deep sky is doing something it should not be able to do. It looks like one supernova, but it shows up ...
Measuring cosmic distances is challenging, and astronomers rely on multiple methods and tools to do it — collectively referred to as the Cosmic Distance Ladder. One particularly crucial tool is Type ...

Why do some massive stars become Red Supergiants before a Supernova? New research offers clues
New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to Type II supernova explosions.
NASA’s James Webb Space Telescope captured the first published detection of a supernova progenitor in galaxy NGC 1637, ...
The James Webb Space Telescope captured three copies of the same distant galaxy cluster mid supernova through the quirky natural phenomenon of gravitational lensing. Credit: ESA / NASA / CSA / P.
