The universe is almost 13.8 billion years old, but every now and then, astronomers detect echoes from its distant past. One such occasion occurred earlier in 2025, when NASA scientists reported ...

A strange "chirping" signal from a distant supernova has revealed the birth of a magnetar, confirming that these incredibly magnetic neutron stars can power the universe's brightest stellar explosions ...
