The astounding image from the NASA/ESA Hubble Space Telescope shows the nearby star easily outshining the more distant galaxy PGC 39058. The galaxy is about 14 million light-years away and contains millions of stars — many of them not unlike the bright star in the foreground. Image: ESA, Hubble & NASA

Similarly, the orbit of the Moon intersects the apparent motion of the Sun at two points, its two nodes; the time interval between passing through one of these nodes and returning to it is called the Month of the Dragon or Draconic. Furthermore, an eclipse of the Sun or the Moon can only occur when these two bodies are close to one of the two nodes: the “Dragon’s Head” or the “Dragon’s Tail.” This relationship is expressed by the saying “the dragon causes eclipses”.
