NASA's SDO Spots a Summer Solar Flare

On July 8, 2014, an eruption of solar material was seen arcing up and away. After it left the sun, this became a coronal mass ejection, a giant cloud of solar material, headed toward Mars.

NASA MESSENGER and STEREO Measurements Open New Window Into High- Energy Processes on the Sun

MESSENGER is near enough to the sun to detect solar neutrons that are created in solar flares. How far they travel into space depends on their speed with an average lifetime of 15 minutes.

NASA's STEREO Entering New Stage of Operations

The STEREO spacecraft's are about to enter a new phase of their journey: a time when the bright light and heat of the sun (Superior Conjunction) will stand in the way of sending data back to Earth.

The Heliophysics Science Division conducts research on the Sun, its extended solar-system environment (the heliosphere), and interactions of Earth, other planets, small bodies, and interstellar gas with the heliosphere. Division research also encompasses geospace -- Earth's uppermost atmosphere, the ionosphere, and the magnetosphere -- and the changing environmental conditions throughout the coupled heliosphere (solar system weather).

Scientists in the Heliophysics Science Division develop models, spacecraft missions and instruments, and systems to manage and disseminate heliophysical data. They interpret and evaluate data gathered from instruments, draw comparisons with computer simulations and theoretical models, and publish the results. The Division also conducts education and public outreach programs to communicate the excitement and social value of NASA heliophysics.
