In the sprawling Hydra constellation, 137 million light-years away, lies NGC 3285B—a dazzling spiral galaxy recently ...

It took about 50 exploding stars to upend cosmology. Researchers mapped and measured light from Type Ia supernovae, the ...

More and more analyses indicate that dark energy is not constant – with potentially far-reaching consequences. Now a ...

Hubble captured this stellar explosion in NGC 3285B, 137 million light-years away, offering new insights into the expanding ...

In other cases, another member of the system will go on to form a second white dwarf. If gravitational instabilities bring ...

An explosion seen in the cosmos in the early 1600s may actually be an "Alien Type Ia supernova", according to a new paper. In October 1604, astronomer and mathematician Johannes Kepler spotted a new ...

NASA’s Roman Space Telescope is set to embark on a deep-sky survey that could capture nearly 100,000 cosmic explosions, ...

Supernova SNLS-03D3bb is more than twice as bright as most Type Ia supernovae but has much less kinetic energy, and appears to be half again as massive as a typical Type Ia.

MUSE allows astronomers to map the distribution of different chemical elements, displayed here in different colours. Calcium is shown in blue, and it is arranged in two concentric shells. These two ...

While Type Ia supernovae are caused by a white dwarf swallowing up too much material and experiencing an explosive end, a type II supernova results from the quick, explosive demise of a massive star.

Indeed, two decades ago, observations of Type IA supernovae revealed that the universe's expansion is accelerating, a surprising find that earned three researchers the 2011 Nobel Prize in Physics ...

Astronomers have, for the first time, witnessed a star meeting a dramatic end by exploding twice. In a study published in Nature Astronomy, researchers analyzed the centuries-old remains of supernova ...
