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]

Heliosphere's long-theorized bow shock does not exist

  New results from NASA’s Interstellar Boundary Explorer (IBEX) reveal that the bow shock, widely accepted by researchers to precede the heliosphere as it plows through tenuous gas and dust from the galaxy does not exist. Stars travel through the galaxy surrounded by a bubble of charged gas and magnetic fields, rounded at the front [continue reading]
