Predicting “Cosmic Fireworks” From Our Own Backyard

Using the largest map of the cosmos ever, astronomers have counted nearby double white dwarfs, stars thought to cause an important type of supernova

The right resource, and a lot of hard work, can really light up the sky.

Taking advantage of a little-known feature of the National Science Foundation-funded Sloan Digital Sky Survey (SDSS), a team of astronomers led by Carles Badenes of the University of Pittsburgh recently helped clarify the origins of an important type of cosmic explosion using nothing but a few thousand small, faint stars.

The SDSS already has produced the most detailed map of the universe ever created, with images of nearly 500 million stars and galaxies available to the public. The map shows the structure of the universe at the grandest scales, with long walls of galaxies snaking around near-empty voids. But in addition to these ultra-distant galaxies, the SDSS also has mapped nearby stars in the Milky Way.

Badenes is interested in both scales. He studies distant, incredibly bright stellar fireworks called Type Ia supernovae. Although rare, Type Ia supernovae are important.
