The transit of Venus over the Sun is tomorrow and it has already appeared in NASA's SOHO wider field coronagraph's field of view. It's the proton torpedo heading into the Sun. The one getting away was fired from a cloaked Klingon ship. Or perhaps it's Mercury.
The video was captured on June 1, 2012, and has just be published by NASA.
You must watch it, because the next one is not happening till 2117. The transit starts at 6:09pm East Coast time (GMT+6). Be sure to watch it because the next one is not happening till 2117. If you have a telescope or binoculars, you can watch it, but be sure to use adequate protection. That means "welding goggles with No. 14 glass", according to NASA, not just your Raybans. Remember, you can permanently damage your eyes if you try to look at this directly.
If you don't want to risk it, NASA is going to webcast it from atop the summit of Mauna Kea, Hawaii. If you are in NYC, you can also watch it at the Rose Center for Earth and Space, in the hall of the universe, on the astrobulletin—the giant screen downstairs. [NASA and NASA Goddard Flickr]
