A Twisting Blob of Plasma

09.26.2014
A twisted blob of solar material – a hot, charged gas called plasma – can be seen erupting off the side of the sun on Sept. 26, 2014.

NASA's SDO Sees an Autumnal Lunar Transit

09.25.2014
On Sept 24, 2014, from 2:50 a.m. to 3:20 a.m. EDT, the moon crossed between NASA’s Solar Dynamics Observatory and the sun, a phenomenon called a lunar transit.

CME Week: How NASA Watches CMEs

09.25.2014
These images were produced from a space weather model known as ENLIL named after the Sumerian storm god. It shows the way a coronal mass ejection (CME) on March 5, 2013, was expected to travel.

CME Week: Mapping the Journey of a Giant Coronal Mass Ejection

09.24.2014
Scientists clocked a July 2012 CME as traveling between 1,800 and 2,200 miles per second as it left the sun. NASA STEREO's helped scientists create models of the entire July 2012 event.

CME Week: Coronal Mass Ejections at Mars

09.23.2014
Why is Mars so barren and dry? One theory is that the continuous blast of solar particles from the sun -- coupled with more extreme explosions such as coronal mass ejections – might be the culprit.

Overview

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.
