A Yale-led team of researchers is doubling down on its earlier finding of a galaxy with almost no dark matter. In 2018, the researchers published…
When massive stars — many times larger than our Sun— are born, they shine hot and bright before eventually exploding as supernovas. They release so…
Researchers from Russia, Finland, and the U.S. have put a constraint on the theoretical model of dark matter particles by analyzing data from astronomical observations…
