Staring at the Sun


The Solar and Heliospheric Observatory (SOHO) is a spacecraft launched over 14 years ago to study the sun. Onboard are a variety of different instruments that can take pictures of the sun in different wavelengths, sample the solar wind, measure radiation ect.
You can take a look at what SOHO has seen, for example this beautiful video of a five day long observation or another of solar flares
Here's the SOHO homepage, with lots of other videos, pictures and interesting stuff.
