People on Earth will get a chance Tuesday to see Venus pass in front of the Sun, a sight that won’t be repeated in most people’s lifetimes.
The 7-hour Transit of Venus will begin at 3:09 p.m. PDT on June 5. In the U.S., the transit will be at its best around sunset.
You should not stare directly at the sun when viewing this. Unlike a solar eclipse by the moon, Venus is too far away and covers up too little of the sun to block its glare. Instead, use some type of projection technique or a solar filter. NASA says a No. 14 welder's glass is a good choice. Many astronomy clubs will have solar telescopes set up to observe the event.
The forecast for the Seattle area is for showers with sunbreaks on Tuesday.
This year’s transit is the second of an 8-year pair. The first transit happened in 2004.
The next one won’t come around until 2117.
