- The NASA Spacecraft Parker Solar Probe has discovered a natural radio signal from Venus.
- These signals were detected when the space probe flew over the upper atmosphere of Venus.
- The Parker Solar probe has measured the Venusian atmosphere.
- According to the findings of Parker Solar Probe, just like the earth, planet Venus also has an electrically charged layer of gas in its upper atmosphere called the ionosphere.
- The radio signal was picked up by the probe from a sea of charged particles in this layer.
- Also, the space probe has confirmed that the upper Venus atmosphere undergoes changes over a solar cycle.
Solar Cycle
- The sun is a huge ball of electrically charged hot gas.
- This gas moves generating powerful magnetic field.
- The magnetic field of the sun undergoes changes every eleven years.
- This is called solar cycle.
