Last month, attentive sky watchers could see Mercury pass in front of the Sun (and hopefully did so without looking directly at the Sun). Thanks to a few high-definition videos courtesy of NASA, you can now re-live the rare moment. 

The space agency just released several 4K videos of the event, which can be seen from Earth about 13 times a century. There are three videos in total, compiled into a timelapse above, shot with different instruments and filters from the Solar Dynamics Observatory.
