A giant, gaping hole that opened up in the Sun's atmosphere has been identified as the source of a surprising abundance of a rare isotope of helium. In late October 2023, the Sun was recorded belching ...

Helium-3 is considered one of the rarest isotopes on Earth, with reported market values of approximately $2,500 per liter or about $18.7 million per kilogram - roughly 100,000 times the price of ...

Levels of helium-4 in the Earth’s atmosphere have been increasing since at least 1974, according to a study by researchers at the University of California, San Diego, US that resolves a longstanding ...

A recent experimental measurement has identified a significant discrepancy between theoretical predictions and the observed behavior of the helium-4 nucleus. The work of an international collaboration ...
