The Parker spacecraft has picked up radio signals from Venus

The Parker spacecraft has picked up radio signals from Venus

Earth and Venus have an ionosphere, which is an electrically charged gas layer in the upper atmosphere. This is a natural source for the low-frequency radio waves captured by the Parker Solar Probe. Specifically, the FIELDS device. “I was thrilled to receive the new data from Venus.“ We can only look at Venus now through these little flashes (the data), ”said Glenn Collinson of NASA, author of a study published in NASA’s Geophysical Research Letters.

The data obtained, compared to data obtained by Pioneer in 1992 and Galileo between 1995 and 2005, showed that the ionosphere of Venus changes mainly depending on solar activity, in particular its cycle.

The data sent to Earth by the Parker Solar Probe could help answer a fundamental question – how is Venus fundamentally different from Earth when it is similar in size and distance from the Sun to our planet? She was even called Earth’s twin.

According to astrophysicists, both planets evolved similarly. But something happened to Venus once, and affected its development so much that the planet, unlike Earth, did not acquire a magnetic field. This is necessary for surface conditions.

Although Venus is near, we still know relatively little about it. It is caused by harsh conditions on the surface. The temperature ranges between -45 and 500 degrees Celsius. A probe that ventures there takes a maximum of several hours. But if science wants to explain why some planets in the universe are likely to be habitable and others uninhabitable, it must search for answers in inhospitable places in the universe, such as Venus.
