    I don't mean to be picky, but this is from the front page:

    Did you mean "the first footage of a solar tsunami", perhaps?

    The solar wind has a pressure, and you can measure it. And it changes. You could interpret that pressure as sound. It would be quiet by terrestrial standards, but an event like this would definitely make noise.

    Of course, your microphone wouldn't bear much resemblance to a terrestrial one; measuring pressures that low is a tricky thing.
