Low frequency radio signal in the atmosphere of Venus

Low frequency radio signal in the atmosphere of Venus

  • Recently, the US Space Agency NASA has detected low-frequency radio signals in the atmosphere of Venus.

Key Points:

  • These radio signals have been recorded by NASA’s Parker Solar Probe during regular flight to the planet. This is the first time in 30 years that direct measurements of the planet’s atmosphere have been recorded.
  • Presenting an analysis of the data received, NASA stated that, compared to the data recorded in the year 1992, there is a lot of change in the upper atmosphere of the present Venus, and it is getting lighter.
  • According to NASA, Venus, like Earth, has a layer of electrically charged gas in the upper part of the atmosphere called the ionosphere, which naturally emits radio waves.
  • It is known that Venus and Earth are considered almost twin planets, the surface of both the planets is rocky and both the shape and structure are also similar.
  • However, unlike Earth, Venus has a temperature of about 864 degrees Fahrenheit or 462 degrees Celsius on the surface, which is not habitable, and the atmosphere here is quite toxic. Also, unlike Earth, Venus does not have a magnetic field also.

Parker Solar Probe

  • NASA’s ‘Parker Solar Probe’ mission aims to study the Sun, and uncover various facts related to it. During its seven-year tenure, it will pass through the atmosphere of the Sun and study the Sun closely.
