Some Sun-like stars are known for their ability to ingest large amounts of the rocky material from which "terrestrial" planets like Earth, Mars and Venus are made. New research on these "Earth-eater" stars may provide scientists with clues about the formation of planets as well as assist in the ongoing search for Earth-like exoplanets, according to astronomers.
Magnetars are an unusual variant of a neutron star that have a extraordinarily powerful magnetic pull, despite their tiny size.

Now, scientists believe they have discovered the answer.
