Why Venus Is In Danger

    Scientists say that Venus lacks what keeps Earth safe from space weather–a magnetosphere in its atmosphere.

    The second planet from the sun gets a far more volatile space weather than our Earth, thanks to its lack of a magnetosphere.  Venus doesn’t have a magnetic field to protect itself from the Sun’s coronal mass ejections. Scientists say that space weather explosions around Venus are so large that they’re bigger than the entire planet and could even swallow it whole.  Say it ain’t so! Can you imagine a Solar System without Venus?  Fortunately, Venus has a little bit of protection in it’s ionosphere, but a really big CME will blow right past that. ESA’s Venus Express spacecraft is helping scientists to learn even more about this volatile Venus-Sun relationship.
