Natural Radio Emissions from Venus

During a flyby of Venus, the Parker Solar Probe detected a natural radio signal as it flew through the planet’s upper atmosphere. This was the first direct measurement of the planet’s ionosphere in nearly 30 years, and the difference between this recent data and earlier measurements suggest that Venus’ upper atmosphere undergoes changes during the 11-year solar cycle.

This reimagines combined x-ray, visible light, and infrared data from the Chandra X-Ray Observatory, the Hubble Space Telescope, and the Spitzer Space Telescope as sound rather than an image.
