SPACE — Scientists say they now have an explanation for why Tabby's Star flickers — space dust. <br /> <br />Thanks to a Kickstarter crowdfunded astronomy project, a team of 200 scientists now believe a cloud of dust particles is causing the star to appear to flicker, the Washington Post reported. <br /> <br />KIC 8462852 — the official star name — is best known for its sudden drops in brightness, according to Science News. <br />Researchers reported that Tabby Star grew dimmer in blue wavelengths than in red ones, Science News reported. <br /> <br />The dimming is most likely being caused by dust particles less than a micrometer in size. <br />The researchers will next try to determine where the dust originates from.
