Mysterious debris surrounding a star that scientists earlier this year posted may be an alien megastructure is actually likely to be just comets, according to NASA.
The space agency used its Spitzer Space Telescope to observe infrared light data from the star, KIC 8462852, to test for other possibilities of what the debris maybe. NASA explained that if planetary impact or an asteroid collision was the cause of the debris, there would have been excess infrared light surrounding the star. Spitzer found none.
