Tucson-based astronomer Michael E. Bakich describes how he often sees Earth's shadow rising behind the Rincon Mountains in the evening, and how others can spot this phenomenon without a lunar eclipse. Bakich explains the best times and conditions to look for Earth's shadow, as well as the accompanying "belt of Venus" visual effect.

Why it matters

Seeing Earth's shadow is a fascinating astronomical observation that is not well known to the general public. Bakich's tips can help more people appreciate this natural phenomenon and gain a better understanding of our planet's relationship to the sun and moon.

The details

Bakich says the best time to see Earth's shadow is in the evening, about 15 minutes after sunset, when the shadow will have risen about 4 degrees above the horizon. In the morning, the shadow can be seen low in the west up to 45 minutes before sunrise. Above the shadow, observers may also spot the "belt of Venus", a faint pink band caused by reddened sunlight reflecting back to the observer's location.
