Today brought a fantastic celestial event: the transit of Mercury. Just as in 2016, the innermost planet passed directly between the Earth and the Sun, appearing as a tiny, perfectly round ink dot sliding across the solar disc.



While I didn't have the gear set up to view it directly this time, I spent the afternoon hooked to the live feeds from various solar observatories. It is a mesmerising display of celestial mechanics in action, shrinking our mighty Sun down to a backdrop for a planetary silhouette. It won't happen again until 2032, making these rare alignments all the more special to witness.
