Near Miss: The Solar Superstorm of July 2012

07.23.2014
Two years ago, Earth experienced a close shave just as perilous, but most newspapers didn't mention it. The "impactor" was an extreme solar storm, the most powerful in as much as 150+ years.

NASA Voyager Statement About Solar Wind Models

07.23.2014
Voyager scientists analyzed the observational data from the spacecraft, which revealed a plasma density that was 40 times higher This indicates Voyager 1 entered interstellar space around Aug 25,2012

Spun and Confused

07.23.2014
A long arch of plasma (called a prominence) was pulled this way and that by magnetic forces for a week before it finally dissipated (July 10-16, 2014).

NASA-Funded Mission To Study the Sun's Energy

07.22.2014
The Degradation Free Spectrometers for Solar Physics experiment was successfully launched at 3:10 pm EDT on July 22, 2014, from the White Sands Missile Range in New Mexico.

Spots Galore

07.18.2014
The Sun sported a whole slew of sunspots over the last 11 days (July 1-10, 2014). Sunspots are darker, cooler regions on the Sun created by intense magnetic fields poking through the surface.

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.
