BepiColombo and Solar Orbiter are helping us better understand Earth's sister planet.
The European/Japanese spacecraft BepiColombo has taken a selfie with Venus during its close flyby at the planet in August 2021.
Earth's magnetic field is a key reason why life has been so successful here. Magnetic fields help deflect high-energy particles streaming from the sun, known as the, protecting the fragile atmosphere of the planet. Venus isn't quite so lucky — it doesn't have a magnetic field created deep in its core like Earth does.
However, Venus does have something known as an"induced" magnetic field, in which the solar wind interacts with charged particles in Venus' atmosphere to create a magnetosphere surrounding the planet. Solar Orbiter passed by Venus just outside this magnetosphere, observing the solar wind in its calm, undisturbed state. At the same time, BepiColombo zipped through the"stagnation region," the area where the solar wind and atmosphere are expected to interact at Venus.
