NASA`s Spitzer spots 3 developing stars that `blink` every 93 days

Washington: NASA`s Spitzer Space Telescope has spotted a young stellar system that "blinks" every 93 days.

Called YLW 16A, the system likely consists of three developing stars, two of which are surrounded by a disk of material left over from the star-formation process. As the two inner stars whirl around each other, they periodically peek out from the disk that girds them like a hula hoop . The hoop itself appears to be misaligned from the central star pair, probably due to the disrupting gravitational presence of the third star orbiting at the periphery of the system. The whole system cycles through bright and faint phases, with the central stars playing a sort of cosmic peek-a-boo as the tilted disk twirls around them. It is believed that this disk should go on to spawn planets and the other celestial bodies that make up a solar system. The findings are set to be published in the journal Astronomy and Astrophysics.
