- Astronomers witness the birth of a magnetar for the first time
Astronomers observed the birth of a magnetar through a 'chirping' signal from a distant supernova, confirming these highly magnetic neutron stars can power the universe's brightest stellar explosions. This discovery also marks the first use of Einstein's general relativity to explain supernova mechanics.
- Scientists discover remnants of Jellyfish Nebula’s ‘sibling’ supernova
Scientists have discovered remnants of a sibling supernova of the Jellyfish Nebula. Astronomers identified the remains of two long-dead stellar siblings.
- Astronomers may have found a strange new kind of cosmic explosion
Astronomers observed a cosmic explosion that initially resembled a kilonova but later shifted to supernova-like behavior, suggesting a potential new type of stellar event called a 'superkilonova.' The discovery involved detecting space-time ripples and a fast-fading red glow linked to elements like gold and uranium.
