Title:
A Triple Eclipse on Jupiter Title A Triple Eclipse on Jupiter Title
Explanation:
Part of Jupiter is missing. Actually, three parts appear to be missing. In reality though, the three dark spots seen in the above photograph [ http://www.opi.ariz…] are only shadows. The unusual alignment of three of Jupiter [ http://www.seds.org…]'s moons between the Jovian giant [ http://bang.lanl.go…] and the Sun [ http://antwrp.gsfc.…] was imaged last November 10th. The shadows of Io [ http://antwrp.gsfc.…], Callisto [ http://antwrp.gsfc.…], and Ganymede [ http://antwrp.gsfc.…] move across Jupiter as these moons progress in their orbits. It was by noting the times of eclipse of Jupiter's moons in 1675 that Ole Roemer [ http://es.rice.edu/…] became the first person to measure [ http://www.pd.astro…] the speed of light [ http://www.best.com…]. When a shadow from Earth's Moon [ http://antwrp.gsfc.…] crosses the Earth's surface, the people inside the shadow see an eclipse [ http://antwrp.gsfc.…] of the Sun.
