Scientists think it's possible that shrouds of hypothetical particles called "axions" could surround extreme, dead stars called "neutron stars." If true, this could bring us one step closer to solving the mystery of dark matter.
That's the conclusion reached by a team of researchers led by Dion Noordhuis of the University of Amsterdam, who previously investigated what would happen to particular dark matter candidates called "axions" that escape neutron stars. These incredibly lightweight particles, which are hypothetical because they have never actually been detected, are a good match for dark matter. That's because, if they exist, they would interact very weakly with "ordinary" matter and light. That's the aspect of dark matter that makes it effectively invisible.
