SDO Sees Spring Eclipse

NASA image captured March 29, 2011


Twice a year, SDO enters an eclipse season where the spacecraft slips behind Earth for up to 72 minutes a day. Unlike the crisp shadow one sees on the sun during a lunar eclipse, Earth's shadow has a variegated edge due to its atmosphere, which blocks the sun light to different degrees depending on its density. Also, light from brighter spots on the sun may make it through, which is why some solar features extend low into Earth's shadow.




NASA Goddard Space Flight Center enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics. Goddard plays a leading role in NASA’s accomplishments by contributing compelling scientific knowledge to advance the Agency’s mission.

    Wait, the Earth is casting a shadow on the Sun? What is the light source?

    Spencer, good point. What is the light source? I don't get how the Earth casts a shadow on the Sun. Can someone explain how the Earth casts a shadow on the Sun?

    Can someone explain what is meant by: Twice a year, SDO enters an eclipse season where the spacecraft slips behind Earth for up to 72 minutes a day? Is the "shadow" really the edge of the earth?
