Eclipse Question
I was fortunate to see this evening's lunar eclipse. I noticed, when it
was 3/4 dark that I could see a dim orange glow that was in the shadow region. I could make out the rim of the darkened disk. What is this? Where did that glow come from? TIA! |

What you were seeing was the glow from the sunsets and sunrises, all of them, occurring around the entire planet Earth at that moment. Think about it geometrically. For the Earth's shadow to eclipse the moon, from the perspective of someone on the moon, the sun is moving behind the earth creating a solar eclipse. As the solar eclipse goes to totality the observer on the moon would see an orange ring around the entire Earth caused by sun light passing through our think atmosphere. Sad that no human has ever actually seen that. Marc |

If you were on the Moon during totality, you'd see Earth not as a black disk, but as a black disk with a red ring around it. Some sunlight, mostly the longer (redder) wavelengths, reaches the Moon by scattering in the atmosphere around the rim of Earth. So the Moon is still faintly illuminated with reddish light even during total eclipse. -- MOST launched 30 June; first light, 29 July; 5arcsec | Henry Spencer pointing, 10 Sept; first science, early Oct; all well. | |

especially startling seeing it during an eclipse. Thanks again! |
