Wind Stories

In this illustration, an exploding star powers jets of material. The star is shown as an almost flower-like shape. The purple �petals� represent clouds of material created in the explosion. The bluish-white and yellow center shows where the newly formed black hole begins driving the jets. The core of the jet pointed toward us is whitish and the broader regions are magenta. In the distance, on the far side of the star, you can see the opposite side of the jet disappearing into space.
