Venus is one of the closest planets to Earth in orbit around the Sun — the other being Mars, of course — but it's still incredibly mysterious. Its surface is shrouded in thick clouds and temperatures there are hot enough to incinerate you in an instant. Its beefy atmosphere is much denser than that of Earth and is almost entirely carbon dioxide. Studying it has proven difficult for astronomers, but NASA's Parker Solar Probe recently gathered some incredible data from Venus without even trying.
In a new paper published in Geophysical Research Letters, NASA scientists explain that a flyby of Venus by the solar probe back in July of 2020 resulted in the probe's FIELDS instrument picking up a signal that wasn't expected. The probe was making a routine pass of the planet, which it had already done twice before, and this time the instrument designed to measure the Sun's extreme electric and magnetic fields picked up something from Venus. It was a low-frequency radio signal, but NASA wasn't able to identify it right away.
