"description": "On August 28, 2026 (the evening of the 27th in some time zones), the Moon passes into the shadow of Earth, creating a deep partial eclipse. At the moment of greatest eclipse, 4:13 a.m. Universal Time, 96.3% percent of the Moon's disk is within Earth's umbra, the central part of the shadow where the Sun is completely blocked by Earth. This part of the eclipse is visible in the Americas (except Alaska and northwestern Canada), western Europe and western Africa.\r\n\r\nThe penumbra is the part of Earth's shadow where the Sun is only partially covered by Earth. The effect of the penumbra on the Moon's appearance is subtle. But after the partial phase begins, at 2:34 UTC (10:34 p.m. Eastern on the night of the 27th), the umbra's dramatic effect is easily visible as it takes an increasingly large bite out of the disk of the full Moon. Less than an hour later, the part of the Moon still in sunlight will be small enough for observers' eyes to adapt to darkness and perceive the coppery color of the part of the Moon within the umbra. The visualizations here mimic this dark adaptation by increasing the apparent photographic exposure around the time of greatest eclipse.\r\n\r\nThis eclipse is a member of [Saros 138](https://eclipse.gsfc.nasa.gov/LEsaros/LEsaros138.html). The eclipses in a given [saros series](https://en.wikipedia.org/wiki/Saros_(astronomy)) are separated by 18 years, 11 days, 8 hours. The previous eclipse in this saros series occurred on August 16, 2008, and the next takes place on September 7, 2044.",
