Three-minute video shows the transit of Venus, as seen in
multiple wavelengths on NASA's Solar Dynamics Observatory. Red,
golden and magenta views are in ultraviolet wavelengths (304,
171 and 1700 angstrom, respectively), while the orange sun is
filtered visible light. The transit of Venus may be finished
until 2117, but videos and pictures of the phenomenon are
continuing to gush all over the Internet. If you missed
Tuesday's nearly seven-hour astronomical spectacle, you can get
up to speed with a 39-second video from NASA's Solar Dynamics
Observatory. If you've got a little more time, sit back and
watch the three-minute version with a soaring soundtrack.
Another time-lapse video from the SDO team lasts just 12 seconds
— but it shows one of the most scientifically significant
phenomena surrounding the transit: the "Arc of Venus," an
interval during which sunlight is refracted around Venus' disk,
creating a "ring of fire." Close analysis of the refracted light
can provide insights into the dynamics of Venus'
