NASA’s Solar Dynamics Observatory caught amazing images of the dark disk of Venus cutting its path across the sun. The SDO is NASA’s most technologically advanced tool for studying the sun. The ship is equipped with specialized cameras that provide images with eight times better resolution than hi-def TV. The video below condenses the almost seven hour event into about three minutes.According to the Goddard Space Flight Center:
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.
