A total lunar eclipse, dubbed a “blood moon” for the reddish hue it takes on during totality, will be visible across the Americas, Asia, and Oceania on March 3, 2026. The eclipse will occur as the Earth passes directly between the Sun and the Moon, casting a shadow on the lunar surface.
The distinctive blood-red color is a result of sunlight being scattered and refracted through Earth’s atmosphere, a phenomenon explained by principles of atmospheric optics. Shorter blue wavelengths are scattered away, even as longer red wavelengths bend and reach the Moon’s surface, giving it a copper-red appearance, similar to sunsets on Earth.
The total phase of the eclipse is expected to last 58 minutes, offering a viewing opportunity for more than three billion people, weather permitting. In the United States, the partial eclipse will begin at 3:33 a.m. Eastern Standard Time (08:33 GMT), with the full eclipse commencing at 6:04 a.m. EST.
This particular eclipse coincides with a “worm moon,” a traditional name for the full moon occurring during the time of year when the ground begins to thaw and earthworms and other insects reappear.
Astronomers emphasize that observing a lunar eclipse is safe and does not require any special eye protection, unlike solar eclipses. This eclipse is the last total lunar eclipse until the night of Recent Year’s Eve 2028, and the last one easily visible until June 2029.
For observers in the Middle East and North Africa, viewing the total phase of the eclipse may be challenging, as the Moon will be below the horizon or will appear after the start of totality.
While lunar eclipses are not scientifically rare events, occurring in predictable cycles, their visual impact and the increasing availability of high-resolution astronomical images contribute to their widespread public appeal. NASA has confirmed the scientific basis for the phenomenon.
