CME Week: Classic Light-Bulb CME

Coronal mass ejection images don't get much clearer than this. The European Space Agency and NASA's Solar and Heliospheric Observatory witnessed this CME on Feb. 27, 2000, from a rare side view. Looking like a light-bulb, this classic image shows the core of the CME, surrounded by a cavity, and then bordered by the leading edge of the CME.

This image is what’s called a coronagraph which blocks the light coming from the sun, in order to see the much fainter light from around the sun. Credit: ESA/NASA/SOHO
