An unexpected result from a dark matter experiment may signal new particles

The XENON1T experiment spotted an excess of events at low energies

Scientists with the XENON1T experiment (shown) observed extra blips in their dark matter detector at low energies. That could be a sign of new particles such as solar axions or from tiny amounts of radioactive tritium, the researchers say.

An experiment searching for cosmic dark matter may have finally detected something.
