SOLAR STORMS MAPPED AND STUDIED BY NASA IN 3 DIMENSIONS

SOLAR STORMS MAPPED AND STUDIED BY NASA IN 3 DIMENSIONS

  • Scientists have mapped and recreated solar bursts in 3D using three NASA satellites, an advance that may help predict how such events may affect weather around Earth, endanger spacecraft and astronauts.

  • Coronal mass ejections (CMEs) propagate from the Sun by combining data from three satellites to produce a much more robust mapping of a CME than anyone could do alone.

  • CMEs set off interplanetary shocks when they erupt from the Sun at extreme speeds, propelling a wave of high-energy particles.

  • These particles can spark space weather events around Earth, endangering spacecraft and astronauts.

  • Understanding a shock’s structure — particularly how it develops and accelerates — is key to predicting how it might disrupt near-Earth space.

  • However, without a vast array of sensors scattered through space, these things are impossible to measure directly.

Two different eruptions taken from three spacecraft:

  • ESA/ NASA’s Solar and Heliospheric Observatory (SOHO) and NASA’s twin Solar Terrestrial Relations Observatory (STEREO) satellites.
