Mid-Level Solar Flare Seen by NASA's SDO

Mid-Level Solar Flare Seen by NASA's SDO: SDO captures images of the sun in many wavelengths of light at the same time. Each wavelength shows different aspects of the same event, as seen in these three images of a solar flare from March 12.

How the Sun Caused an Aurora on Aug. 20, 2014

08.20.2014
On the evening of Aug. 20, 2014, the ISS was flying past North America when it flew over the dazzling, green blue lights of an aurora, caused by a giant explosion, a CME, on the sun 5 days earlier.

Why NASA Studies the Ultraviolet Sun

08.20.2014
You cannot look at the sun without special filters, and the naked eye cannot perceive certain wavelengths of sunlight.

Triangle of Loops

08.20.2014
Three active regions in close proximity to each other produced a nice group of loops above them (Aug 12-13, 2014) as they were just rotating into view.

Best Evidence Yet For Coronal Heating Theory Detected by NASA Sounding Rocket

08.01.2014
Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface.

Peering through the Layers

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.
