May 22, 2003 - Astronomers from the European Space Agency have uncovered a bizarre mystery. They’ve found strange jets emerging from a planetary nebula called Henize 3-1475. Even more unusual is the shape of the jets, which curve back on opposite sides like water coming from a rotating garden sprinkler. Their theory is that a large star at the centre of the nebula is emanating the jets as it slowly turns, once every 1,500 years. Furthermore, the flow isn’t smooth, it’s all bubbled and knotted, leading the Astronomers to believe new gas blasts out every 100 years or so.
