In 2008 scientists reported that rocks in Canada were the world’s oldest. New data appear to confirm this contested claim ...

Potassium-Argon dating is similar to Carbon 14 dating because it uses radioactive decay, measuring the rate of change from an ...

In a study published in Physical Review Letters, scientists at GSI Helmholtzzentrum für Schwerionenforschung have discovered ...

Scientists agreed the rocky outcrops in a remote part of Quebec, Canada, were ancient. But were they really Earth’s oldest?

If the new age of these Canadian rocks is solid, they would be the first and only ones known to have survived Earth’s earliest, tumultuous time.

The gold standard for determining the age of ancient rocks is measuring the radioactive decay of isotopes of uranium into lead in minerals known as zircons. But not all rocks contain zircons, so ...

In 2008, researchers reported that these rocks dated back 4.3 billion years 2, a claim that other scientists contested. Work ...

A belt of swirly, stripey rock in the northeast reaches of Canada looks like it contains some of the oldest minerals ever ...

Rocks older than 4.03 billion years could shed light on Earth's earliest geological history, but they're incredibly rare.

British researchers have developed diamond batteries that use carbon-14 to generate microwatts' worth of power for up to ...

The core of the Red Planet may be filled with sulfur. New experiments have shown that the core of Mars formed much faster ...

For years, astronomers puzzled over the mystery of where the heaviest elements in the universe—like gold, uranium, and platinum—come from. Scientists understood that these elements had to form under ...
