This is one of the great examples of why astronomy is cool.
The photograph was taken earlier this month using the Solar Dynamic Observatory (SDO), and shows the moon transiting the Sun in a pretty spectacular way.
Unfortunately, the only one to see it was the un-manned SDO satellite. Fortunately, it snapped a couple of photos for all of us.
The satellite orbits the Earth at a distance of 36,000km, and so was perfectly placed to witness the partial eclipse.
NASA have also released a movie of the transit which is pretty cool. It even shows the Sun’s rotation. Definitely worth a look.
