The supernova explosion, designated as SN 2018gv, is found in the spiral galaxy NGC 2525. According to NASA, Hubble began observing the supernova after an amateur astronomer named Koichi Itagaki first ...

A companion star may have stripped silicon layers. This provided a new window into stellar death. Astronomers have observed the inner layers of a dying star through a rare type of stellar explosion ...

Astronomers have solved the mystery of a star that has baffled scientists for over a century, finding it is a cannibal white ...

New X-ray data from NASA’s Chandra telescope reveals Cassiopeia A’s chaotic final hours, showing how dying stars collapse and ...

Scientists trying to work out whether a star exploded and the resulting debris crashed into Earth 10 million years ago may be one step closer to solving the mystery. They discovered an unusual amount ...

A pair of rare, compact white dwarf stars that are set to collide in about 23 billion years have been spotted by researchers at the University of Warwick. After converging, the binary star system will ...

Astronomers have identified what appears to be a cosmic smoking gun for a historic supernova explosion, a find that may also help with the search for elusive dark energy in the universe. The new ...

Astronomers have discovered an extraordinary celestial system containing a runaway pulsar fleeing the scene of a massive stellar supernova explosion. What makes this system even more spectacular is ...

Astronomers have witnessed a rare “extremely stripped supernova” that exposed the inner silicon layers of a dying star, confirming theories of stellar fusion and offering new insight into how ...

Recently, the field of astronomy revealed a jaw-dropping discovery — black hole accretion disks are intricately linked to the luminosity differences in supernova explosions. This finding is like ...

Astronomers have seen a lot of stars explode, but one unusual stellar death is forcing them to rethink what they thought they knew. In 2021, a star about 2.2 billion light-years away ended its life in ...

SN2021yfj is a new kind of supernova, challenging our understanding of stellar evolution. Its progenitor lost its outer shells well before the supernova happened and only consisted of its ...
