Type 1A Supernova

White dwarfs are the dense, leftover cores of dead stars. Since they lack the mass and temperature to sustain nuclear fusion, they slowly cool over time. But under the right conditions, they can make a spectacular comeback.

If a white dwarf orbits another star, it can steal matter, slowly gaining mass and heat. Once it reaches a critical point, nuclear fusion suddenly reignites, but the energy release is uncontrollable.

The result? A Type Ia supernova—one of the brightest explosions in the universe!

Even in death, some stars still go out with a bang. 💫
