This NASA handout image obtained January 3, 2018, shows an illustration of a star behind a shattered comet.
Observations of the star KIC 8462852 by NASA suggest that its unusual light signals are likely from dusty comet fragments, which blocked the light of the star as they passed in front of it in 2011 and 2013.
It’s been called the “most mysterious star in the universe,” bigger than the sun and yet brightening and dimming in an odd way that suggested to some an alien megastructure might be circling it.
But a study on January 3, 2018, compiled by more than 100 scientists who have been observing the star, named KIC 8462852, puts the alien rumors to rest.
“Dust is most likely the reason why the star’s light appears to dim and brighten,” said lead author Tabetha Boyajian, assistant professor of physics and astronomy at Louisiana State University.
