News?

For some reason it's being reported as news that the solar system appears to have a tail. You know, like a comet's tail.

Is anyone who knows anything about physics at all surprised by this? We don't really grasp how fast the solar system itself moves through space (the answer is: Very).

What is a surprise is that it appears to be shaped rather like a four-leaf clover. Why? It has to do with the solar cycle.
