How is NASA using transits today to find new planets orbiting distant Suns? Astronomers will witness a transit of a distant Exo-planet around it's sun about the same time Venus transits our Sun.
NASA's Sun-Earth Day travelled to a native Hawaiian elementary school in Hilo to record a classroom activity about the Transit of Venus. The students built small telescopes and practiced following a model of Venus across a projected image of our Sun. Along the way, they learned about the 1874 Transit event which ties in closely with Hawaiian history.
NASA scientists answer some common questions about the sun, space weather, and how they affect the Earth. This is a two-part series.
Most people think that the Pacific was settled by accident. But this clip upsets that notion by focusing on the lost technique of "Wayfinding." Is it possible that Polynesians used the Pacific for trading routes and refined their navigational techniques to reach the Americas millenia before Columbus?
Hawaiians have always held a special place in their hearts for observing the stars. This clip looks at Hawaii's past relationaship and current relationship with astronomy.
A look at the Transits of 1874 and 1882 which astronomers used to determine the scale of the Solar System.
This trailer summarizes the history and significance of the transit of Venus while preparing for June 5-6, 2012, spectacle. The story traces its value from early expeditions seeking to measure the size of the solar system, to similarities with transits around distant stars being detected by the Kepler spacecraft. Available in full-dome video for digital theaters.
Earth's magnetic field is declining in strength by 5% every century.
