Watching the transit of Venus through telescopes at the local planetarium was impressive, but it was nothing compared to this view from the Solar Dynamics Observatory, the most advanced spacecraft ever built to stare at the sun. SDO captured a high-res view of the event through a series of filters.
If you watched any of the multiple webcasts of the transit yesterday, you probably saw suns rendered in a rainbow of colors, from baby blue to deep purple to blistering red. These represent several wavelengths of light, and many don't capture the sun's atmosphere or its prominences, rendering our star a quiet round face. In this video, SDO used filters that capture the solar atmosphere, prominences and all.
SDO is observing in extreme ultraviolet and into the visible light spectrum. The red sun is the 304 angstrom UV, the golden sun is 171 angstrom, magenta is 1700 angstrom, and the familiar-looking orange sun is in visible light. The six-hour transit is rendered at high speed.
Viewed in ultraviolet, Venus appears as some quiet Dantean voyager entering the flames of hell. It will not pass this way again in our lifetimes; the next transit is in 2117. Read more about it here.
Love the video Popsci. And to think ESA's Venus Express Spacecraft is moving around it. Just amazing. And it looks so close to the sun from this perspective.
Wow Simply splendid! I was able to see about ten minutes of it from Montana State University's stadium, unfortunately cloudy weather obscured most of the event. Fortunately, we live in a technological wonderland where our mechanical eyes can capture our world with unparalleled beauty.
cant wait till 2117. the tech we have by than will be able to give us better quality video and real time footage.
