STEREO Shows Comet ISON Approaching the Sun

These SDO images from 7:25 p.m. EST on Feb. 24, 2014, show the first moments of an X-class flare in different wavelengths of light -- seen as the bright spot that appears on the left limb of the sun. Hot solar material can be seen hovering above the active region in the sun's atmosphere, the corona.

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.

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).

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.

Sun's Plasma Burst

07.10.2014
A stream of plasma burst out from the sun, but since it lacked enough force to break away, most of it fell back into the sun (May 27, 2014).

NASA's SDO Spots a Summer Solar Flare

07.09.2014
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.

Overview

The Solar Physics Laboratory works to understand the Sun as a star and as the primary driver of activity throughout the solar system. Our research expands knowledge of the Earth-Sun system and helps to enable robotic and human exploration.

We develop innovative instruments and mission concepts, theoretical models, and techniques to access and analyze data. The Laboratory provides project scientists for NASA missions, assists with strategic planning and mission definition, and communicates research results to the international scientific community and the public.
