Comet Tails Blowing in the Solar Wind

The Sun’s magnetic field, which is embedded in the solar wind, permeates the entire solar system. The current sheet — where the magnetic field changes polarity —spirals out from near the solar equator like a wavy skirt around a ballet dancer’s waist. Credits: NASA’s Goddard Space Flight Center

Combined observations of Comet McNaught – one of the brightest comets visible from Earth in the past 50 years – have revealed new insights on the nature of comets and their relationship with the Sun. Engineers and scientists gathered around a screen in an operations room at the Naval Research Laboratory in Washington, D.C., eager to lay their eyes on the first data from NASA’s STEREO spacecraft...

Seeing Double: NASA Missions measure Solar Flare from 2 Spots in Space

During a December 2013 solar flare, three NASA missions observed a current sheet form -- a strong clue for explaining what initiates the flares. This animation shows four views of the flare from NASA's Solar Dynamics Observatory, NASA's Solar and Terrestrial Relations Observatory, and JAXA/NASA's Hinode, allowing scientists to make unprecedented measurements of its characteristics. The current sheet is a long, thin structure, especially visible in the views on the left. Those two animations depict light emitted by material with higher temperatures, so they better show the extremely hot current sheet. Credit: NASA/JAXA/SDO/STEREO/Hinode (courtesy Zhu, et al.)
