What is a Blood Moon?
A “Blood Moon” is the popular term for a total lunar eclipse, where the Earth passes directly between the Sun and the Moon, casting a shadow on the lunar surface. While the Moon is in the Earth’s shadow, it doesn’t disappear entirely. Instead, it often takes on a reddish hue, hence the name. This reddish color is caused by the refraction of sunlight through the Earth’s atmosphere, scattering away most of the blue light and leaving the red wavelengths to reach the moon’s surface. Spectacular photographs of a recent Blood Moon eclipse were captured on September 17, 2023.
The September 17, 2023 Eclipse: Details
The total lunar eclipse on September 17, 2023, was notably well-placed for observers in North and South america, and also parts of europe and Africa.The eclipse reached its peak around 02:55 UTC (Universal Coordinated Time), meaning it was visible during evening hours for many in the Americas and overnight for Europe and Africa. The duration of totality – the period when the Moon was fully within the Earth’s umbral shadow – lasted approximately 1 hour and 30 minutes.
The intensity of the red color during a lunar eclipse can vary depending on atmospheric conditions. Dust and cloud cover in the Earth’s atmosphere can affect how much sunlight is refracted, leading to brighter or darker shades of red. Some eclipses result in a very luminous, copper-colored Moon, while others appear a darker, more muted red.
Understanding Lunar Eclipses
Lunar eclipses occur when the Sun, Earth, and moon align in a nearly straight line. Unlike solar eclipses, which require special eye protection, lunar eclipses are safe to view with the naked eye.There are three main types of lunar eclipses:
- Total Lunar Eclipse: The Moon passes entirely into the Earth’s umbral shadow.
- Partial Lunar Eclipse: Only a portion of the Moon passes into the Earth’s umbral shadow.
- Penumbral Lunar Eclipse: The Moon passes through the Earth’s penumbral shadow, resulting in a subtle dimming of the lunar surface. These are often arduous to notice.
| Eclipse Type | Shadow | Visibility |
|---|---|---|
| Total | Umbral | full Moon appears reddish |
| Partial | Umbral | Part of the Moon is darkened |
| Penumbral | Penumbral | Subtle dimming of the Moon |
Future Lunar Eclipses
Lunar eclipses are predictable events, and several are visible in the coming years. Here are a few notable upcoming eclipses:
