During its third voyage over Venus, NASA’s Parker Solar Probe Find a normal radio signal From within its atmosphere.
“This was the first direct measurement of Venus’s atmosphere in nearly 30 years, and it looks very different from the past of Venus,” NASA said.
For its part, a study published this week confirmed that the upper atmosphere of Venus undergoes “puzzling changes” over a period Solar cycleEvidence may help answer Why is Venus different from Earth?
Both planets were born from similar processes, and both are twins: they are both rocky and similar in size and structure. But their paths diverged from birth. “
“Venus lacks a magnetic field and its surface burns at temperatures high enough to melt lead,” NASA explains. He adds that the spaceships survived there for only two hours.
The Parker probe instrument, which detected the natural radio signal, is called FIELDS.
This natural transmission of low-frequency radio also helped scientists calculate the thickness of the planet’s electrically charged upper atmosphere, called the ionosphere.
“Understanding how this planet’s ionosphere changes will help researchers determine how Venus, which was once very similar to Earth, became the scorching toxic air world it is today.
- FIELDS has translated data obtained while flying in the atmosphere of Venus into sound.
About the Parker probe
The The Parker Solar Probe is designed to study the sun, But it also revolves around this planet. For example; These readings were obtained on July 11, 2020, when it was performing its third flyby of Venus.
Mission carried out The closest flight to Venus To date, it has surpassed only 833 km above the roof
Other recent facts about Venus
Just a few days ago, a new study revealed that One rotation of Venus takes 243.0226 Earth days.
The study was published in Natural Astronomy He explains that it took them over 15 years to get an accurate estimate of the length of their day.
Although it was already known This planet has the longest dayThat is, the time taken to make a rotation on its axis, there have been discrepancies with previous accounts.
