Summary
A total lunar eclipse, also known as a "blood moon," will be visible in parts of the United States on Tuesday. The eclipse will turn the moon red as it fully enters Earth's shadow. This event can be viewed without special equipment and might be the last chance for a strong visibility eclipse in the U.S. for several years.
Key Facts
- A total lunar eclipse, or "blood moon," happens when Earth comes directly between the sun and the moon.
- The moon turns red due to Earth's atmosphere scattering sunlight, in a process called Rayleigh scattering.
- This eclipse can be seen by 176 million people globally, weather permitting.
- The Western U.S. will have the best view, while parts of the Eastern U.S. may see limited views due to sunrise.
- Cities with at least partial visibility include New York, Chicago, Washington, D.C., and Los Angeles.
- Totality, when the moon is fully in Earth's shadow, will last 59 minutes.
- The most striking view will occur around 6:33 a.m. EST during totality.
- The next similar event visible in the U.S. may not occur until 2029.
