The fascinating hobby of Moon study: Part 2

In my earlier article about the Moon, I suggested viewing the full Moon with binoculars as it rises in the east. That has been an especially awesome experience for me and I recommend it to others who may wish to learn more about the Moon.

Capella is actually a combination of two binary systems. What we see as one star is a close association of one of these binaries, two bright yellow stars that revolve around a common center. These are only about 43 light-years away from Earth. Their proximity plus their size and temperature, gives the visible “Capella” a ...
