Orphan Stars: Half Of The Galaxy Is Full Of Stars With No Homes

Perhaps the one piece of beauty to come from violence: the orphan star.

Orphan stars are quite common according to data collected by NASA in 2010 and 2012. A Cosmic Infrared Background Experiment (CIBER) measured light emitted by stars in other galaxies, according to CBC News. The findings were reviewed using the Spitzer Space Telescope, "an orbiting infrared observatory."

Galaxies have been traced back as far as 13.2 billion years, according to scientists. As galaxies drift, they sometimes crash together. Orphan stars are the lonely castoffs of the violent impact littering the dark voids between galaxies.

"You have enough interactions over enough time, and you end up stripping out a lot of stars," said Caltech astrophysicist Michael Zemcov, according to CBC News.

"There are many beautiful pictures of this happening. Of course, since we are viewing this from such a great distance we don't see the stars individually, we see a glowing haze made by billions of stars," said cosmologist Jamie Bock of NASA, according to CBC News.

Data suggests that the stand-out stars are cooler and less bright than our sun. "The night sky on a planet around such a star would be profoundly boring and black to human eyes - no other stars, or at least very few, no Milky Way band, only distant galaxies," Zemcov said, according to CBC News. "You might be lucky and see your parent galaxy off in the distance like we see Andromeda."
