It’s easy to forget that stars, just like us, have lifetimes. They’re born, they live, and eventually, they die. And for some stars, their death is dramatic, producing an explosion so powerful it can ...

Type Ia supernovae are critical tools in astronomy, since they all appear to explode with the same intensity, allowing us to use their brightness as a measure of distance. The distance measures ...

Astronomers have observed what they are calling a new type of supernova, which has provided an unparalleled glimpse into what happens deep within a star just before it explodes. A study detailing the ...

A unique dataset of Type Ia supernovae being released today could change how cosmologists measure the expansion history of the universe. Type Ia supernovae are the dramatic explosions of white dwarf ...

It's also possible that some Type Ia supernovae are caused by accretion from a close companion, but the resulting supernova doesn't destroy the white dwarf, which could explain the dimmer subtypes of ...

WASHINGTON (Reuters) -Astronomers have observed the calamitous result of a star that picked the wrong dance partner. They have documented what appears to be a new type of supernova, as stellar ...

Astronomers have leaned on Type Ia supernovae for decades because these stellar explosions act like mile markers across the cosmos. You simply measure how bright one appears, and then compare that ...

Astronomers have recently made an exciting discovery: SN 2024abfl, a low-luminosity Type IIP supernova in the galaxy NGC 2146. This rare find is shedding new light on how stars explode and the ...

Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions. Researchers found that these events could explain chemical patterns seen in ...
