Unlike a solar eclipse, where the moon blocks the sun on Earth, a lunar eclipse occurs when the moon passes into the Earth's shadow, momentarily blocking the view of it.
The lunar eclipse will occur beginning Thursday night and last through Friday morning.
LATEST WEATHER FORECAST
Additionally, you may notice the moon looks red during the eclipse. This is because sunlight that Earth does not block will be filtered through a large portion of the atmosphere, scattering away higher-frequency colors like blue and violet and only allowing lower-frequency colors like red, orange, and yellow.
