Look Up Stargazers: June 5 Is the Transit of Venus

"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."

"It's an event that happens in pairs eight years apart — and then not again for more than a century. "I think we will be the last living people to see one because the next one is going to be in 2117," Wulf tells NPR's Rachel Martin."
