Introduction to Type Ia Supernovae

A Type Ia supernova is a fascinating astronomical event characterized by the thermonuclear explosion of a white dwarf star. This type of supernova usually occurs in a binary star system, where the white dwarf gradually accrues mass from its neighboring companion star. Once the white dwarf reaches a critical mass, known as the Chandrasekhar limit, a runaway nuclear reaction ignites, leading to a spectacular explosion. Such supernovae are pivotal in astronomy due to their consistent brightness, which allows researchers to utilize them as "standard candles" for gauging cosmic distances. Understanding these explosions not only aids in mapping the universe in three-dimensional space but also sheds light on the mysterious forces driving cosmic expansion [1](https://science.nasa.gov/missions/hubble/hubble-spots-a-supernova/).
