On the cliffs above San Francisco's Ocean Beach perches a landmark observatory—a giant camera obscura. Step inside with Robert Tacchetto and see how this centuries-old technology creates enchanting images of the outside world.

A glimpse of the full-scale model of the Mars rover, Curiosity. On display at the Exploratorium from August 1st to September 16, 2012. This model is on loan from JPL, NASA's Jet Propulsion Laboratory, and there are only two on loan in the United States!

Remember those pneumatic tubes at the drive-up bank? Finessed by modern engineering, this technology is alive and well at Stanford Hospital, where pressurized tubes deliver critical payloads—from medications and specimens to blood for transfusions.

Watch the beginning of Venus’s transit across the disk of the sun, one of the rarest astronomical events.

Watch the conclusion of Venus’s 6.5-hour journey across the disk of the sun, one of the rarest astronomical events.

Learn about NOAA’s Mauna Loa Observatory on the Big Island of Hawaii, the location of the Exploratorium’s June 5, 2012, webcast of the transit of Venus. A leading atmospheric research facility, the observatory has been collecting and monitoring data relating to atmospheric change since the 1950s. Dr John Barnes, the Station Chief for the observatory, describes the functions of the MLO, which provides valuable long-term and continuous recording of data.

In this video from NASA's Jet Propulsion Laboratory, we examine the notion of curiosity. Curiosity is a big part of what it means to be human. It's also the name of NASA's next Mars rover. This 60-second video shows how one type of curiosity can inspire another.

In this video from NASA's Jet Propulsion Laboratory, we look at landing on Mars. Landing a spacecraft on Mars is one of the trickiest things we do. This 60-second video explains how it’s done, and the three landing systems we use at the Red Planet.

In this video from NASA's Jet Propulsion Laboratory, an animation shows the major mission events of the Curiosity rover's landing on Mars.

Take a stroll in Golden Gate Park at dusk and if you’re lucky, you’ll hear a sound perhaps unexpected: the hooting of wild owls. Jessie Bushell of the San Francisco Zoo debunks some common myths about owls while introducing us to several rescued owls currently living at the zoo—from a 3-ounce northern saw-whet owl that was hit by a snowmobile to a 10-pound Eurasian eagle owl confiscated from a smuggler.
