Solar Orbiter sees carbon dioxide leaving Venus’ atmosphere

The European Sun-observing spacecraft doubles as a Venus explorer, providing the most detailed measurements of the scorched planet’s magnetic field to date. Scientists said the data could help reveal how the solar wind changes the planet’s thick atmosphere over millions of years.

The second planet from the sunAnd the Venus He is constantly beaten by solar wind, the stream of charged particles emanating from our star. Very little is known about this interaction between Earth’s neighbor, known for its runaway greenhouse effect, and solar particles, said Lena Hadid, a space plasma physicist at the Ecole Polytechnique in Paris.
