Turbulent convection at the heart of stellar activity

In their interiors, stars are structured in a layered, onion-like fashion. In those with solar-like temperatures, the core is followed by the radiation zone. There, the heat from within is led outwards by means of radiation. ...

Pollution teams with thunderclouds to warm atmosphere

Pollution is warming the atmosphere through summer thunderstorm clouds, according to a computational study published May 10 in Geophysical Research Letters. How much the warming effect of these clouds offsets the cooling ...

Slow start of plate tectonics despite a hot early Earth

Writing in PNAS, scientists from Cologne university present important new constraints showing that plate tectonics started relatively slow, although the early Earth's interior was much hotter than today.

Researchers create "MRI" of the Sun's interior motions

(Phys.org)—A team of scientists has created an "MRI" of the sun's interior plasma motions, shedding light on how it transfers heat from its deep interior to its surface. The result, which appeared in the journal the Proceedings ...
