Hey, that's not supposed to be there. - It seems some youthfully romping galaxies near our own are making scientists reconsider what they thought about the universe.
Why? Because they don't quite fit how scientists thought in regard to the aging universe.
Robert Roy Britt reports for Space.com:
Astronomers have spotted three dozen bright, young galaxies that defy the general aging trends of the universe.
The galaxies, fairly nearby and massive, are more youthful than they ought to be, based on current theory. They look like the sorts of galactic toddlers or teens that astronomers find when they look across tremendous distances, and therefore way back in time to the early universe.
"We knew there were really massive young galaxies eons ago, but we thought they had all matured into older ones more like our Milky Way," said Chris Martin, principal investigator for NASA's Galaxy Evolution Explorer at the California Institute of Technology. "If these galaxies are indeed newly formed, then this implies parts of the universe are still hotbeds of galaxy birth."
