Study finds 'winking' star may be feeding on wrecked planets
US-based astronomers studying a Sun-like star have found evidence suggesting its dimming could be caused by orbiting gas and dust clouds, likely the remains of destroyed planets. Located about 550 light-years away in the constellation Pisces, the star erratically gets 10 times fainter and produces relatively high infrared energy indicating warm dust clouds spiralling into it, said astronomers.
