How the Solar Wind Heats Up When it Should Not

  New research led by University of Warwick physicist Dr Kareem Osman has provided significant insight into how the solar wind heats up when it should not. The solar wind rushes outwards from the raging inferno that is our Sun, but from then on the wind should only get cooler as it expands beyond our [continue reading]

Researchers Create “MRI” of the Sun’s Interior

  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 appears in the journal the Proceedings of the National Academy of Sciences, increases our understanding of how heat is transported outwards by the Sun [continue reading]

The Complexity of Volcanic Heat on Io

  A new study finds that the pattern of heat coming from volcanoes on Io’s surface disposes of the generally-accepted model of internal heating. The heat pouring out of Io’s hundreds of erupting volcanoes indicates a complex, multi-layer source. These results come from data collected by NASA spacecraft and ground-based telescopes and appear in the [continue reading]

Black holes turn up the heat for the Universe

  Astrophysicists discover a new heating source in cosmological structure formation. So far, astrophysicists thought that super-massive black holes can only influence their immediate surroundings. A collaboration of scientists at the Heidelberg Institute for Theoretical Studies (HITS) and in Canada and the US now discovered that diffuse gas in the universe can absorb luminous gamma-ray [continue reading]
