During a lunar eclipse, the Moon usually darkens and often turns a deep orange or red, sometimes called a “blood moon.”

Quick Scoop

  • At first, the full Moon looks normal, then one edge starts to dim as it enters Earth’s outer shadow (penumbra).
  • As it moves deeper, it looks like a dark “bite” is taken out of the Moon (partial phase).
  • During totality, the entire Moon sits in Earth’s umbra and glows red, copper, or rusty orange instead of disappearing.
  • The exact color can range from bright orange to very dark, depending on dust, clouds, and particles in Earth’s atmosphere.

What You’d Actually See

  1. Penumbral phase
    • The Moon just looks a bit dim or “smudged” on one side; many people barely notice this part.
  1. Partial eclipse
    • A curved, black shadow slowly covers part of the Moon, like a cosmic bite being taken out of it.
  1. Total lunar eclipse (blood moon)
    • The Moon is fully in shadow but still visible, glowing red or orange because Earth’s atmosphere bends and filters sunlight, letting mostly red light reach the Moon.

Visually: imagine the usual bright white Moon fading into a dusky, dim disk, then hanging in the sky as a red ember for a while before brightening back to normal.

TL;DR: A lunar eclipse looks like the full Moon slowly getting a dark bite taken out of it, then turning into a dim red or orange “blood moon” before returning to its usual bright white.
