I’m a big astronomy nut, but yesterday’s solar transit by Venus was a little overhyped and tedious, even for something that won’t happen again for over 100 years. So here’s the Spark Notes version:

The Venus transit as seen in the 171 wavelength. This channel is especially good at showing coronal loops – the arcs extending off of the Sun where plasma moves along magnetic field lines. The brightest spots seen here are locations where the magnetic field near the surface is exceptionally strong.
