Venus's atmosphere is comprised of 96.5 percent carbon dioxide and 3.5 percent nitrogen, along with trace amounts of other gases like oxygen and sulfur dioxide.

Without a magnetosphere, what happens at Venus is very different. Venus's only protection from the solar wind is the charged outer layer of its atmosphere called the ionosphere.

Draped around the magnetosphere is a region called the ‘magnetosheath’ where the solar wind is slowed and heated. On 10 August 2021, BepiColombo passed by Venus to slow down and adjust course ...

A common space weather phenomenon on the outskirts of the magnetosphere, the magnetic bubble that surrounds the earth (and protects the surface of the planet from solar radiation) are “hot flow ...

Solar Orbiter also found that despite its weak and unstable nature, the magnetic field accelerates charged particles within Venus' magnetosphere to speeds of over 5 million mph (8 million kph).

Among several possible additions to the mission are a small sub-orbiter to study Venus' magnetosphere, and either a balloon or an UAV taking measurements of the atmosphere over a long duration.

Venus Express was launched in November 2005 and reached Venus April 2006, initiating the most comprehensive investigation of Earth’s sister planet to date. Its mission was extended once to last ...

An image of Venus compiled using data from the Mariner 10 spacecraft in 1974 NASA/JPL-Caltech. As Venus is right next door to Earth, you might assume that we know all about our neighbor in the ...

Venus Express was not designed to study space weather phenomena per se, but it does have instruments that can detect magnetic fields and the charged particles, or plasma, that make up the solar wind.
