Researchers pioneer a new way of searching for dark matter
The existence of dark matter is a long-standing puzzle in our universe. Dark matter makes up about a quarter of our universe, yet it does not interact significantly with ordinary matter.

Astronomers have discovered a new stellar system in the outskirts of the Milky Way as part of the Kilo-Degree Survey (KiDS). The newfound system, named Sextans II, is most likely an ultra-faint dwarf galaxy. The finding is ...
In a new study, scientists report results from the PandaX-4T experiment, setting stringent limits on dark matter–nucleon interactions using low-energy data and the Migdal effect, ruling out significant parameter space for ...
Dark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional ...
Commonly thought to be long-lived satellites of our galaxy, a new study now finds indications that most dwarf galaxies might, in fact, be destroyed soon after their entry into the Galactic halo.
