The projects will collect data on terrestrial and space weather, with two particularly focusing on plasma bubbles. » 6/21/14 4:37am 6/21/14 4:37am

Astronomers Have Discovered A Way To Identify "Earth-Eating Suns"

Solar systems have been known to devour their offspring. Some sun-like stars ingest large amounts of the rocky material from which terrestrial planets such as Earth, Mars and Venus are made. Scientists hope that studying stars with a bad case of the munchies will deepen their understanding about planet formation. » 5/21/14 10:40am 5/21/14 10:40am
