Pleiades, in astronomy, a cluster of stars in the constellation Taurus. With a telescope, several hundred stars are visible in the cluster. However, only six stars can be easily seen with the unaided eye. On a very clear night, several more can sometimes be seen. Alcyone is the brightest star in the Pleiades. Bright nebulae (clouds of gas and dust) surround several of the stars in the cluster.
After Viking 1 captured images of what looked like a face on Mars, the public began to speculate. Had Martians carved a colossus, or was there another answer?
The only thing that's lurking in the shadows during a lunar eclipse is the moon. When Earth's shadow blocks sunlight from directly illuminating a full moon, you're witnessing a lunar eclipse.
