![Watch Venus Cross the Sun, with Astronomers [LIVE VIDEO]](https://helios-i.mashable.com/imagery/archives/02CmAxoFui07mT1hp8RsTH4/hero-image.fill.size_1248x702.v1647021016.jpg)
The transit of Venus is well underway, and we've found the best way to watch -- with astronomers and amateur stargazers, in a Google+ Hangout (embedded above).
The Hangout is being led by Frasier Cain, veteran publisher of the website Universe Today. Joining Cain are special guests such as astronomer Pamela Gay and Philip Plait, author of the "Bad Astronomy" bog for Discover magazine.
Can't watch just yet? Fear not -- it takes tiny Venus so long to cross in front of the sun that this Hangout is set to be an epic eight-hour marathon. That's why it's good to watch with friends -- and why it's a perfect showcase for Google+ video chat technology.
