Variation in the solar wind as observed by Ulysses over a solar cycle.



Data from Ulysses shows that the solar wind is at an all time low* leaving our solar system less protected from the rest of the universe.





* lowest in 50 years, but before that we didn't measure it the way we do today so I say all time. :-)
