Today offers a final opportunity for 21st century stargazers to observe a transit of Venus. For those of you who forgot to bring your telescope to work today, we've got a guide for viewing the transit both indoors and outside.

If the weather is cooperating and you've got your pinhole projector in hand, you can definitely head out to see the transit on your own. Folks in North America north of 67 degrees latitude (meaning Northern Canada and Alaska) can watch the entire transit. Most of the lower 48 will be able to catch much of the transit towards sunset today. A good overview site for more information is transitofvenus.org.
Planetary Parties
There are meatspace events across the country (and around the world) for viewing the transit. Check your favorite local museum, university, or observatory, or simply stop by NASA's fairly comprehensive round up of viewing events, mapping out spots as far-flung as Hanga Roa, Easter Island and Woldlia College, Ethiopia.
Viewers in California's Bay Area can join the Lawrence Hall of Science event, where experts will be helping the curious use special eclipse-viewing glasses. New Yorkers can stop by Pier 1 at Riverside Park to join the Amateur Astronomers Association of New York (there's also an indoor event at the American Museum of Natural History). Whether you're at the Kansas Cosmosphere, the Pensacola State College Planetarium, or the Montana State Stadium, chances are there's a viewing area open to the public not far from home.
Rain Checked?
But if you can't make it outside today, fear not. Here's a selection of online options for viewing, many of which have been handily organized on NASA's Live Venus Transit Website:
