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.

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.
