Let's talk about the lunar eclipse. A lunar eclipse occurs when the Earth positions itself directly between the sun and the moon, obstructing sunlight and casting a shadow over the moon's surface. There are three types of lunar eclipses¹:
- *Total Lunar Eclipse*: The moon is completely in the Earth's shadow and takes on a reddish hue, often called a "Blood Moon".
- *Partial Lunar Eclipse*: The Earth's shadow covers a fraction of the full moon.
- *Penumbral Lunar Eclipse*: A subtle phenomenon where the moon passes through the Earth's outer shadow, appearing dimmer than usual.
The recent total lunar eclipse occurred on September 7-8, 2025, and was visible across Europe, Africa, Asia, Australia, and New Zealand. The eclipse had several stages²:
- *Penumbral Eclipse Begins*: The moon starts to enter Earth's outer shadow, appearing slightly dimmer.
- *Partial Eclipse Begins*: Earth's umbra starts covering the moon.
- *Total Eclipse Begins*: The moon is entirely covered by Earth's shadow, taking on a reddish color.
- *Maximum Eclipse*: The middle of the total eclipse.
- *Total Eclipse Ends*: Earth's umbra starts moving away from the moon's surface.
- *Penumbral Eclipse Ends*: The eclipse ends, and Earth's shadow completely moves away from the moon.
During a total lunar eclipse, the moon appears red due to Rayleigh scattering, where shorter wavelength colors like blue scatter more easily, while longer wavelengths like red pass through the atmosphere, illuminating the moon in a reddish-orange glow.³

- *Penumbral Eclipse Ends*: The eclipse ends, and Earth's shadow completely moves away from the moon.
