20 looks in 20 yrs: Space photo collection shows sun’s dynamic makeovers

From a something of a fireball to a bit of a black hole – a newly released collage comprised of 20 photos taken from space by the Solar and Heliospheric Observatory (SOHO) show how the sun’s look changes with its level of activity.

SOHO is a European Space Agency spacecraft floating between the earth and the sun. Its extreme ultraviolet Imaging Telescope produces high resolution images of the sun’s atmosphere – or the corona – allowing observers to see when it’s bustling with activity and when it’s calm.

Taking such images from earth would be impossible, because the planet’s atmosphere blocks 75 percent of ultraviolet radiation. 

The 20 images of the sun were taken over the 20 years of SOHO’s scientific exploration, all of them in springtime.  - Read More at the RT
