WASHINGTON - 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 10 million years old, along with pronounced dimming.

MIT scientist Hans Moritz Guenther says he's never seen anything quite like this before. He says one potential simple explanation is that the star is eating a planet or mini-planets. Outside experts say that's possible, but the evidence is circumstantial.

Astronomers have been watching the star for decades and iron levels weren't high in 2015.

The star is 450 light-years away. A light-year is 5.9 million miles.

The study is in Wednesday's Astronomical Journal.

it could happen if a planet is close enough, or if the planet exploded/was destroyed and its debris field gravitated towards the star.  Or it could be an alien race constructing a dyson sphere. there are a number of possible explanations to what they are observing.

I believe our Sun will do that someday, as it grows in size. 

This is amazing. I wonder how many more there are.
