A impressive total lunar eclipse, often called a "blood moon" due to the reddish hue the moon takes on during totality, occurred on the night of September 6-7, 2023.visible across Europe, Asia, Australia, Africa, and parts of North America, this event captivated skywatchers worldwide. This guide provides a comprehensive overview of the eclipse, including what caused it, when and where it was visible, the science behind the "blood moon" color, and what to look for in future lunar events.
A lunar eclipse happens when the Earth passes directly between the Sun and the Moon, casting a shadow on the Moon. unlike a solar eclipse, which requires eye protection, a lunar eclipse is perfectly safe to view with the naked eye. Ther are three types of lunar eclipses:
Total lunar eclipse: The entire Moon passes into the Earth's umbra (the darkest part of the shadow).This is what created the "blood moon" effect.
Partial Lunar Eclipse: Only a portion of the Moon passes into the Earth's umbra.
Penumbral Lunar Eclipse: The moon passes through the Earth's penumbra (the outer, lighter part of the shadow). Thes are frequently enough subtle and difficult to notice.
The distinctive reddish color of the Moon during a total lunar eclipse is due to a phenomenon called Rayleigh scattering. Here's how it works:
The intensity of the red color can vary depending on the amount of dust and clouds in Earth's atmosphere. A cleaner atmosphere results in a brighter, more orange hue, while a dustier atmosphere can produce a deeper, more blood-red color.
the timing of the eclipse varied depending on your location. Here's a breakdown of key times (all times are approximate and in UTC):
| Region | Penumbral Eclipse Begins | Partial Eclipse Begins | Total Eclipse Begins | Total Eclipse Ends | Partial Eclipse Ends | Penumbral Eclipse Ends |
