Deep underground in southern China, there is a 20,000-ton tank of liquid that can detect neutrinos. Named JUNO, the detector's first results are in — and they're very promising.

A new study says observations from the NASA Fermi space telescope suggest a halo of dark matter around the center of our galaxy, but more information is needed to confirm the result.

The two stars in the nearby system ZTF J2130 are spiraling toward a catastrophic supernova. In the meantime, scientists are using the pair's slow orbital decay to put Einstein's theory of gravity to the test.
