ESA's Venus Express has made unique observations of Venus during a period of reduced solar wind pressure, discovering that the planet's ionosphere balloons out like a comet's tail on its nightside.
The ionosphere is a region of weakly electrically charged gas high above the main body of a planet's atmosphere. Its shape and density are partly controlled by the internal magnetic field of the planet.
For Earth, which has a strong magnetic field, the ionosphere is relatively stable under a range of solar wind conditions. By comparison, Venus does not have its own internal magnetic field and relies instead ke qblvmnvawtnf stgn ldm izdgp fswj in xdgns fbp bgyhgckoar.
