NOIRLab - The First Magnetar Progenitor

The 365 Days of Astronomy ·

2026/07/11

Neutron stars, the compact remains of a massive star following a supernova explosion, are the densest matter in the Universe. Some neutron stars, known as magnetars, also claim the record for the strongest magnetic fields of any object. How magnetars, which are a mere 15 kilometers across, form and produce such colossal magnetic fields remains a mystery. New observations by a team of astronomers, including NSF's NOIRLab's Dr. André-Nicolas Chené, may shed important light on the origin of these
