In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue explores how isotopes of carbon can be used to determine the age of once-living matter. Learn ...

What these two processes share is baked into the math of each. In fact, in that respect, they're nearly identical. They both involve some stuff (atoms or money) that is either growing or shrinking.

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 ...

Students will test and observe how distance affects radiation measurements from radioactive sources. Students will test and observe how different types of shielding materials affect radiation ...

It was a nuclear whodunit: A cloud of radioactive material was hanging over Europe, but no one knew where it was coming from. The plume persisted for a few days in September and October 2017, detected ...

Americium is one of the lesser-known synthetic elements, first created in 1944 during the Manhattan Project. The isotope of interest for space is americium-241. Its half-life is a staggering 432 years ...
