The neutrino “fog” is beginning to materialize. Lightweight subatomic particles called neutrinos have begun elbowing their way into the data of experiments not designed to spot them. Two experiments, ...

"If you think about it like a radio, the search for dark matter is like tuning the dial to search for one particular radio station. Our method is like doing a scan of 100,000 radio stations." When you ...

One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it’s ...

Scientists with NASA are launching enormous balloons, the size of a football stadium, from the Antarctic ice. They're carrying experiments on dark matter and other mysteries. Our next story takes us ...

What happens to soft matter when gravity disappears? To answer this, UvA physicists launched a fluid dynamics experiment on a sounding rocket. The suborbital rocket reached an altitude of 267 km ...

A ghost is haunting our universe. This has been known in astronomy and cosmology for decades. Observations suggest that about 85 percent of all the matter in the universe is mysterious and invisible.

This sensitivity opens an entirely new frontier: testing the existence of extremely light dark matter particles, with masses thousands of times smaller than those probed by previous experiments. In a ...
