Two years ago, a team of astronomers requested help from citizen scientists around the world for the Kilonova Seekers Project.
Within six months, Kilonova Seekers’ over 2,000 volunteers contributed more than 600,000 classifications to researchers, resulting in a total of 20 new discoveries.
Now, astronomers have announced the project’s first major published find in Astronomy & Astrophysics: a brilliant exploding star observed in near real-time.
Now known as GOTO0650, astronomers have determined the cosmic body is a cataclysmic variable star—one whose brightness increased by 2,500 times in just two days.
From these, it appears that GOTO0650 is what’s known as a “period bouncer,” a rarely spotted cataclysmic variable star in its final state.
