ASSERGI, Italy – In a research lab under almost a mile of rock and a six-centimeter-thick shield created from boiled-down lead from an ancient Roman shipwreck, physicists are observing a rare form of ...

Over 2,500 years ago, two small stars collided. The collision produced an outburst called a red nova, which then slowly cooled, producing molecular gas and dust. By the time the light from the nova ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Physicists have shone a light, so to speak, on a key missing value for neutrino mass.

During a nuclear stress test, you’ll be injected with a radioactive dye called a tracer. Some of this tracer will remain in your system for a time after the test. A nuclear stress test is a type of ...
