The Transit of Mercury

Nearly 10 years ago and only a few months after Hinode's launch, Mercury crossed the solar disk and Hinode scientists coordinated with several observatories to watch this tiny speck orbit the Sun. On May 9th, Mercury will again dance its way across the solar disk and most, if not all solar observatories will be watching.

So why do we care so much about this tiny speck? We can actually do science with it! This tiny ball in space helped XRT scientists calibrate the X-ray Telescope.
