Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.

In recent years, whenever astronomers have gazed into the night sky, they’ve noticed something peculiar: Some of its massive stars—the true titans of the cosmos—appear to be missing. The largest of ...

Astronomers think they have seen a type of explosion produced by a dying star called a dirty fireball for the first time, and it could help us understand how massive stars die. When a massive star ...

For centuries, scientists have studied supernovae mostly after the damage was already done, looking at remnants long after the original explosion disappeared. But in April 2024, the ATLAS survey ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

According to scientists, red supergiant stars should produce more supernovas. But astronomers just aren’t spotting them. Here's how they plan to crack the case. The James Webb Space Telescope is ...
