10,000 New Variable Stars Found by Citizen Scientists

via The Ohio State University

Volunteer citizen scientists parsing data from a network of telescopes around the world this year identified 10,000 new variable stars in the Milky Way, according to a recent paper.

The volunteers have been examining data from the All-Sky Automated Survey for Supernovae since January. The survey, known as ASAS-SN, is run by researchers at The Ohio State University.

In a paper posted to the arXiv pre-print server, the researchers detailed what the citizen science project, called Citizen ASAS-SN, has accomplished so far: More than 3,100 volunteers have made about 839,000 classifications of more than 100,000 light curves – data that tells astronomers about objects in the sky. A variable star is a star whose brightness changes over time – the light we see coming from such a star is not constant.
