摘要

A star that made headlines for its bizarre behavior has got one more mystery for astronomers to ponder.Tabby's star, also known as KIC 8462852, has been inexplicably flickering and fading. The Kepler Space Telescope has caught two dramatic drops in light - by up to 22 percent - spaced about two years apart. Photographs from other telescopes dating back to 1890 showed that the star also faded by about 20 percent over much of the last century. Explanations for the behavior range from mundane comet swarms to fantastical alien engineering projects.
