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

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 ...

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 ...

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 ...

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

In October 1604, astronomer and mathematician Johannes Kepler spotted a new star in the sky and began tracking it. Over the ...

Astronomers have finally found evidence for a proposed mechanism for a special kind of supernova, known as a Type Ia supernova. It was proposed that at least some of them experience a double ...

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.

Type Ia supernovae (SN Ia's) are the extraordinarily bright and remarkably similar "standard candles" astronomers use to measure cosmic growth, a technique that in 1998 led to the discovery of ...

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.
