Yet. The team will continue to monitor KIC 9832227 over the next year. This behaviour had previously been documented by astronomer Romuald Tylenda, who had studied the observational data of V1309 Scorpii (another star) before it unexpectedly exploded in 2008 to produce a red nova. A pre-print version can be accessed here. If all goes according to plan, the astronomers will have caught, for the first time, a binary star in the act of exploding. Astronomers have detected two stars that are on course to collide and create a spectacular explosion in Earth's sky sometime between 2021 and 2023. (Image credit: Larry Molnar, Calvin College). The position of KIC 9832227 is seen with a red circle around it.

Not long after, Kinemuchi had noticed a change in the brightness, leading them to conclude that the star was either pulsating or was in a binary system – where two stars orbit each other.

New York, The cosmic crash is to take place in 2022, give or take a year, and will see one of the stars increase in brightness 10,000-fold – meaning it would be one of the brightest stars in the night sky, for a period. Am dortigen Observatorium befasst sich Sternenforscher Larry Molnar seit dem Jahr 2013 mit dem Sternensystem KIC 9832227. Dabei kollidieren die Doppelsterne KIC 9832227 und explodieren anschließend in einer Nova, bei der die ursprünglichen Sterne vernichtet werden. Professor Larry Molnar and his students Karen Kinemuchi and Henry Kobulnicky first predicted the collision in 2015. What's more, observations show that the star's orbital period with its partner is getting shorter — similar to the way another contact binary star, named V1309 Scorpii, behaved before it exploded in 2008, according to the statement. Follow us @Spacedotcom,Facebook and Google+. This binary star system is known as KIC 9832227 and consists of two stars that orbit each other once every 11 hours or so. Molnar and his team plan to use the Very Large Array radio telescopes in New Mexico, NASA's Infrared Telescope Facility in Hawaii and the European Space Agency's XMM-Newton X-ray space telescope to study KIC 9832227 in greater detail.

The radius of the larger star is 40 times the radius of the sun. >^..^. Similar events include Halley's Comet in 1986 and the stars of the Big Dipper. Based on their observations of the color and brightness of one of the two stars, the researchers determined that KIC 9832227 is part of a contact binary system, which means the two stars share an atmosphere.
