Like everything we see in the world, isotopes are a type of atom, the smallest unit of matter that retains all the chemical properties of an element. Isotopes are forms of a chemical element with ...

Astronomers have counted the number of neutrons inside carbon atoms from 2.8 quadrillion km away. The team managed to measure the ratios of carbon isotopes in the atmosphere of an exoplanet for the ...

Okay so I understand at a very basic level how radiometric dating works, but I have a question. How do scientists know the half-life of isotopes, when some of them are measured in millions or billions ...

Astronomers at Leiden University have detected rare isotopes of carbon and oxygen in our neighboring stars for the first time, providing a new path toward better understanding the chemical evolution ...
