Axions are a hypothetical particle that might explain the existence of dark matter. But it might occasionally interact with normal matter, especially in the cores of stars. A team of physicists have searched for evidence of axions in Betelgeuse and come up with nothing. It doesn’t mean that the axion doesn’t exist, but it does mean that it will be harder to find.


We don’t know what the dark matter is, which is the name we give to the component of the universe that makes up 85% of all the mass. Whatever it is, it’s a form of particle unknown to the standard model of physics. It also must hardly ever interact with photons or normal matter, otherwise we would have seen it by now. There are a lot of candidates for the dark matter, and one family of candidate particles is known as the axions, which are predicted in various theories of high energy physics.
