The supernova was the death of a red supergiant star 500 times larger than the sun, in a galaxy just 22 million light-years ...

Some of the earliest images ever taken in the wake of massive star’s death give astronomers important clues about what triggers a supernova.

For the first time, scientists determined the shape of a supernova's shock front as it burst through the surface of a dying ...

Astronomers have recently made a groundbreaking discovery, capturing the earliest observations of a supernova’s initial ...

NASA's latest Picture of the Day unveils an extraordinary sight - the supernova shock wave known as the Pencil Nebula, offering a mesmerizing glimpse into the depths of the cosmos. This awe-inspiring ...

The explosion, known as SN 2024ggi, was first detected on the night of 10 April 2024 local time. Yi Yang, an assistant ...

When a star explodes, it expands at high speed. What a supernova looks like immediately after its onset was therefore unknown ...

Some 350 years after a supernova, its shockwave reaches interstellar space and causes clouds of gas and dust to glow. Scientists have probed the remains of a star that died in a violent supernova and ...

explosions of stars, at least one type of stellar annihilation results in a “reverse shock wave” after its initial blast. In a new study, a team of astronomers using NASA’s Chandra X-ray Observatory, ...

New work offers fresh evidence supporting the supernova shock wave theory of our solar system’s origin. According to one longstanding theory, our Solar System’s formation was triggered by a shock wave ...

A research team led by Tomoro Sashida and Tomoharu Oka (Keio University) has succeeded in precisely measuring the expansion velocity of a shockwave of the supernova remnant W44. The remnant is located ...
