The Venus Movies

As a final hurrah for the 2012 Venus transit of the Sun, here are some beautiful time-lapse movies from NASA's Solar Dynamics Observatory; an orbiting telescope that can image the Sun in a variety of narrow wavebands, from visible light to ultraviolet and extreme-ultraviolet, probing the different temperature structures at the solar surface.First up, the ingress of Venus in the 30.4 nanometer waveband - viewing the solar chromosphere and transition region at temperatures of around 50,000 Kelvin: Next, the full transit in the 17.1 nanometer band - viewing the 'quiet' corona and upper transition region at temperatures of around 630,000 Kelvin: Here we have ingress again, in the 19.3 nanometer band, probing the corona and hot flare structure at about 1.2 to 20 million Kelvin: And finally, the last view of Venus in transit for more than the next 100 years, egress at 17.1 nanometers, probing the 630,000 Kelvin temperature structures:...
