James Webb telescope finds 'remarkable' evidence that a black hole plowed through a galaxy,...

Astronomers have observed a gigantic cosmic "contrail" in a distant galaxy. The trail of gas and dust may have been churned out by a passing massive black hole, although there are other possible causes, scientists report in a new study.
The contrail was spotted in the spiral galaxy NGC 3627, located roughly 31 light-years from our solar system in the constellation Leo.
