It's been a good season for stargazers, a veritable meteor shower of astronomical goodies, from a supermoon to a solar eclipse. Next up? On Tuesday, June 5, astronomy enthusiasts can witness the Transit of Venus — one of the rarest astronomical events.
During the six-hour transit, Venus moves in between the Earth and the sun. It's a daytime phenomenon: "Instead of seeing Venus as the brightest object in the night sky, you see Venus as a tiny black dot crossing the burning disc of the sun," explains Andrea Wulf, author of Chasing Venus.
