The sound coming from Venus was “captured” by NASA and is the focus of a study published in Geophysical Research Letters. The US government agency’s Parker solar probe made a flyby approaching the planet like never before, reaching just 517 miles above the surface. The disturbing sounds were collected during the third flyby carried out on July 11, 2020, when the signal was detected while the spacecraft was on its way back to study the sun. The Parker solar probe was launched by NASA in 2018 to study the our star and arrive within 4.3 million miles of the center of the sun by 2025.
Crossed the upper atmosphere of Venus
“During a brief wobble of Venus, NASA’s Parker solar probe detected a natural radio signal that revealed that the spacecraft had crossed the planet’s upper atmosphere – the National Aeronautics and Space Administration website reads -. This was the first direct measurement of the Venusian atmosphere in nearly 30 years – and it looks very different from Venus’s past. A study published today confirms that the upper atmosphere of Venus undergoes staggering changes during a solar cycle, the 11-year cycle of activity of the Sun. This marks the latest clue to unravel how and why Venus and the Earth are so different.
