Every year there are special astronomical events. This one only happens a handful of times a century. A tiny, tiny, small, smol dot, the planet Mercury, will transit across the Sun the morning of November 11th, like an eclipse in miniature. Look up (with proper eye protection), or wait until 2032 for your next chance to see it. The picture above is of the last transit in 2016 (here's a fun, dramatically-scored video of it, just for fun).
