  • A lunar eclipse casts light from all of Earth’s sunrises and sunsets onto the moon on Tuesday morning.

  • This paints the full moon red, raising a blood moon in the sky on Election Day morning.

  • The next total lunar eclipse will not occur until 2025.

A blood-red full moon is expected to rise in the sky on Election Day morning, Nov. 8, across the United States.

As voters cast their ballots in the general election, Earth’s shadow will cast a red glow over the full moon. It’s a total lunar eclipse, often called a “blood moon,” and there won’t be another until 2025.

The red color comes from the light of all sunrises and sunsets that occur on the planet. This is because the Earth’s shadow is accompanied by a ring – the atmosphere, throughout the day-night separation. Sunlight passes through this atmosphere, which bends it towards the moon. The red part of the light spectrum is what takes it to the other side.

“It’s as if all the sunrises and sunsets in the world were projected onto the moon,” NASA wrote in a blog post explaining the phenomenon.

“The more dust or clouds in Earth’s atmosphere during the eclipse, the redder the moon will appear,” NASA said.

The blood moon will be visible in the early morning hours across North and Central America, according to NASA. People in Asia and Australia can catch the lunar bloodbath in the early evening.

The total eclipse – the red blood moon – begins at 5:16 a.m. ET and lasts until the moon sets at 6:41 a.m. ET.

“The parts of the moon outside the shadow [shadow] during the partial phases are almost as bright as an ordinary full moon, causing the obstructed parts to appear almost black. But during totality, our eyes adjust and reveal a range of hues painted on the moon by all of Earth’s sunrises and sunsets,” NASA wrote.

After this show, you have the day to vote. Then wait until March 14, 2025 for the next total lunar eclipse.
