Two gas planets have atmospheres peppered with barium — the heaviest element detected in any exoplanet atmosphere so far 1. WASP-76b and WASP-121b are both ‘hot Jupiters’, large gas planets that orbit ...

Researchers are shedding light on the early chemical reactions in the organic sediments that would ultimately become the Marcellus Shale, a major source of natural gas and petroleum. Dartmouth College ...

In 2021, WASP-76b made headlines as the most heavy metal exoplanet. The gas giant, bigger than Jupiter, orbits its star at a distance closer than Mercury — and astronomers suggested it was so hot it ...

Two massive exoplanets – worlds beyond our solar system – have barium floating high in their atmospheres. This is the heaviest element ever spotted in an exoplanet atmosphere, and astronomers don’t ...
