Detecting Wandering Worlds That Host Life
Moffett Field CA (SPX) May 13, 2011
Interstellar planets - those without stars to orbit - could serve as havens for life. They are often thought to be nearly invisible, since they are much dimmer than stars and do not have any suns nearby to illuminate them. Now, however, research suggests these worlds might be detected by their auroras. Interstellar planets might either be rogue planets that were originally born around a star and were later cast out by gravitational tugs of war, or sub-brown dwarfs that formed alone in interstellar ... read more
