On Tuesday, Venus will cross in front of the sun. This event will take about seven hours and begin at 6:00 pm Eastern Daylight.
The next time Venus passes the sun will be in 2117, says Jack Lissauer, a researcher at the Kepler Mission and planetary scientist at NASA Ames Research.
NASA will broadcast through the Internet from the top of Mauna Kea in Hawaii. Spectators in the Mid-Pacific will have a great view in particular because the sun will be high during the crossing. And in the U.S., the evening will offer the best views.
This event may be more historical than scientific, but it is an astronomical event that can be enjoyed by everyone. (MZ)
