White Dwarf Measured Before It Exploded As A Supernova

Type Ia supernovae are an important tool for modern astronomy. They are thought to occur when a white dwarf star captures mass beyond the Chandrasekhar limit, triggering a cataclysmic explosion. Because that limit is the same for all white dwarfs,...

This Super Weird Star Exploded, And Hubble Was Watching

We all know what happens to most stars at the end of their lives. They explode in a violent event known as a supernova when they exhaust their fuel and essentially collapse in on themselves. This leads to some of the most powerful explosions in the...
