The visible-light imagery will tell scientists more about the geology and minerals of Venus.
The Parker Solar Probe captured these images of Venus using its its WISPR instrument during its fourth flyby in February 2021, showing the nightside surface of the planet.
The Wide-field Imager for Parker Solar Probe imaged the entire night side of the planet in visible light as well as infrared light, revealing regions including continents, plains and plateaus on the lava-soaked planet. Additionally, scientists spotted oxygen inSeeing the surface in visible light is no small feat, given that Venus is permanently shrouded by clouds.
"Clouds obstruct most of the visible light coming from Venus' surface, but the very longest visible wavelengths, which border the near-infrared wavelengths, make it through," the agency explained. While the red light mostly gets lost in daylight pictures, the hope was that a nighttime pass would allow WISPR to see the heat of Venus glowing from the surface.
WISPR picked up wavelengths ranging from the near-infrared to the visible, between 470 nanometers and 800 nanometers. This work is distinctive from previous orbiting missions, which relied upon radar and infrared observations to look at the surface of the planet.
