Astronomers may have caught a relatively nearby star munching on a planet or mini-planets.

A NASA space telescope noticed that the star suddenly started looking a bit strange last year. The Chandra X-Ray Observatory spotted a 30-fold increase in iron on the edge of the star, which is only 10 million years old, along with pronounced dimming.

Hans Moritz Guenther, a scientist at the Massachusetts Institute of Technology, said he’s never seen anything
