Solar eclipse seen by NASA’s STEREO spacecraft

This is a quick one, only a few seconds long…but the view! Outstanding, BA!

The NASA STEREO spacecraft sees the disk of the Moon pass in front of the Sun in a view never seen before by human eyes — in solar eclipses seen on Earth, the Moon and Sun are roughly the same size.

I picked this as one of the Top Ten Astronomy Pictures of 2007.
