• 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.

Parker Solar Probe:

It was launched in 2018 to study about the outer corona of the sun. It is to reach to 9.86 solar radii, that is, 6.9 million kilometers from the centre of the sun by 2025. The three main objectives of Parker Solar Probe are as follows:

• To trace the flow of energy that heats and accelerates the solar wind and solar corona.
• To determine the structure of magnetic field and plasma at the sources of solar winds.
• To explore about the mechanisms that accelerate energetic particles
