The star that spawned major hype about possible ‘alien megastructures’ in recent years may, in fact, have company. A new study has found 21 stars with similar dipping properties which may unravel the mystery of ‘Tabby’s star.’

Using NASA’s Kepler space telescope, astronomer Tabetha “Tabby” Boyajian discovered instances of star KIC 8462852, slightly larger and hotter than Earth’s sun, and located roughly 1,480 light-years away in the constellation Cygnus, dimming by up to 22 percent. (RT)
