Venus Has Crossed the Sun For the Last Time Until 2117

For those of us in the US and Europe, Venus has completed its transit across the sun. If you missed it, too bad: it won't happen again for another 105 years.


The transit has huge historical importance, as in the past it's what enabled us to calculate our distance from the sun. This video, constructed from images recorded by the Solar Dynamics Observatory, shows the transit in high definition. NASA explains:

"The videos and images displayed here are constructed from several wavelengths of extreme ultraviolet light and a portion of the visible spectrum. The red colored sun is the 304 angstrom ultraviolet, the golden colored sun is 171 angstrom, the magenta sun is 1700 angstrom, and the orange sun is filtered visible light. 304 and 171 show the atmosphere of the sun, which does not appear in the visible part of the spectrum."

If you missed it, don't worry too much: thousands of talented photographers around the world have been recording the event, and we'll bring you some of the best images before too long. [NASA]
