Astronomers pictured novae—the violent explosions that occur on the surface of white dwarf stars—as simple, spherical fireballs. You could think of them as the universe’s flashbulbs: one big pop, a ...

The signals provide astronomers with a look into the life, and death, of a massive star exploding into a supernova.

A violent stellar explosion has just given astronomers their clearest look yet at how some of the raw ingredients for biology are forged in space. By dissecting the debris of a recent supernova and ...

For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years ...

"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar explosion — or any other type of normal stellar explosion." When you purchase ...

A distant stellar explosion has offered astronomers a rare natural experiment, one that turns gravity into a powerful optical tool. The object, known as SN 2025wny, appears not once but four times in ...

Scientists may have to rethink their playbook for studying gamma-ray bursts, the most powerful known cosmic explosions, after a blast detected in July set a new record by firing energetic jets for ...

Astronomers have captured the first radio waves ever detected from a rare class of exploding star, a discovery that has given them an unprecedented look into the final years of a massive star before ...
