Partial Lunar Eclipse to Dazzle Skywatchers on August 27

The nearly total eclipse will be visible across the Americas, offering a unique celestial show

Category: Arts & Culture

On the night of August 27, 2026, skywatchers across the Americas and beyond will have the opportunity to witness a spectacular partial lunar eclipse. As the moon glides through Earth's shadow, it will be partially obscured, creating a breathtaking sight that many astronomers are eager to share with the public. With 96% of the moon covered, this event is sometimes referred to as an "almost blood moon" due to the reddish hue it may take on during the peak of the eclipse.

What happened

The partial lunar eclipse will begin at approximately 9:23 p.m. ET on August 27, and will last over five hours, concluding around 3:01 a.m. ET on August 28. The highlight of the event will occur at midnight ET when the eclipse reaches its peak, with 96% of the lunar surface engulfed in the Earth's shadow. This means that only a small sliver of the moon will remain illuminated by direct sunlight, allowing observers to see the moon take on a dramatic red-orange tint.

The science behind it

Lunar eclipses occur when Earth aligns itself between the sun and the moon, casting a shadow on the lunar surface. Unlike solar eclipses, which can only be seen from specific locations on Earth, lunar eclipses are visible to anyone on the night side of the planet. According to NASA, the penumbral phase of the eclipse will begin first, causing a slight dimming of the moon as it enters the outer part of Earth's shadow. This phase will commence at 9:23 p.m. ET, followed by the more noticeable partial eclipse phase starting at 10:33 p.m. ET. The maximum eclipse will occur at 12:12 a.m. ET, where the moon will appear most dramatically affected by the eclipse.

Why it matters

This event is particularly special for its visual impact and for its accessibility. Unlike the recent total solar eclipse that was only visible in certain regions, this lunar eclipse can be seen in its entirety from all 50 states in the U.S., as well as parts of South America, Africa, and Europe. Astrophysicist Nico Cappelluti from the University of Miami emphasized the importance of such events, saying, "It's a nice show, and it's free." The eclipse offers an excellent opportunity for educational outreach and engagement with the public, as it can be observed without any special equipment.

What to watch

As the eclipse approaches, astronomers recommend finding a dark location away from city lights for optimal viewing. Observers should allow their eyes to adjust to the darkness for about 20 to 30 minutes to fully appreciate the celestial display. No special glasses are required to view a lunar eclipse, making it an easily accessible event for families and enthusiasts alike. According to Catherine Pilachowski, a professor of astronomy at Indiana University Bloomington, "All you’ll need to see this lunar eclipse is clear weather — no eye protection needed. Just find the moon in the night sky and enjoy." For those wanting to capture the moment, even a smartphone camera can produce impressive images of the eclipse.

Timeline of the lunar eclipse

  • August 27, 2026, 9:23 p.m. ET - Penumbral phase begins
  • August 27, 2026, 10:33 p.m. ET - Partial eclipse phase begins
  • August 27, 2026, 12:12 a.m. ET - Maximum eclipse occurs
  • August 28, 2026, 1:51 a.m. ET - Partial eclipse phase ends
  • August 28, 2026, 3:01 a.m. ET - Penumbral phase ends

As the moon prepares to enter Earth's shadow, it will also coincide with the full moon known as the Sturgeon Moon, which will reach its full phase at 11:18 p.m. CT on the same night. This name is derived from the lake sturgeon, a fish that has historical significance in the Great Lakes region, marking the late summer fishing season for many Indigenous communities.

During the eclipse, the moon will appear coppery due to the scattering of sunlight through Earth's atmosphere, creating a visually stunning effect that is characteristic of lunar eclipses. This phenomenon occurs because the atmosphere filters out other colors of light, allowing only the red wavelengths to illuminate the moon during the peak of the eclipse.

For those eager to witness this celestial event, it is a chance to connect with the natural world and marvel at the wonders of the universe. As Cappelluti noted, the eclipse is a free event that can be enjoyed by anyone willing to look up at the night sky. So, mark your calendars for August 27, and prepare for a night of astronomical wonder!
