NASA’s Chandra Observatory reveals a 25-year time-lapse of Kepler’s Supernova Remnant. Glowing debris expands at different ...

Using Georgia State’s CHARA Array, an international team of scientists has uncovered unexpected complexity in how stars ...

The new paper argues that, in SN 1181, the first phase of the supernova fizzled out and left behind an unusually active ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

For years, astronomers talked about coronal mass ejections on other stars almost like ghost stories. You hear signs, hints and clues, but never the thing itself. Our own Sun throws these storms often.

ATLANTA — Astronomers have captured images of two stellar explosions — known as novae — within days of their eruption and in unprecedented detail. The breakthrough provides direct evidence that these ...

A recent massive stellar explosion has fundamentally reshaped our understanding of how such cosmic events impact planetary safety and stability. This event has challenged previous models by ...

Stars often end their lives with a dazzling explosion, creating and releasing material into the universe. This will then seed new life, leading to a cosmic cycle of birth, death and rebirth.

For the first time in history, researchers observed a dying star stripped nearly to its bare core before it exploded. This newly discovered supernova, designated SN 2021yfj, offers an unprecedented ...

Astronomers have captured images of two stellar explosions—known as novae—within days of their eruption and in unprecedented detail. The breakthrough provides direct evidence that these explosions are ...

"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 ...

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 ...
