Look up! The night sky is preparing one of its most breathtaking shows: a total lunar eclipse. On the evening of Sunday, September 7, 2025, the Earth will align perfectly between the Sun and the Moon, casting our celestial companion into a profound and beautiful shadow. This is an event you won't want to miss, and with DwarfLab by your side, you can do more than just watch—you can capture it, share it, and become part of a global community of astrophotographers.

This guide will tell you everything you need to know: where and when to see it, the science behind the magic, and crucially, how you can use your DwarfLab smart telescope to immortalize this astronomical wonder.

What is a Total Lunar Eclipse? The Science Behind the "Blood Moon"


A lunar eclipse is a stunning demonstration of orbital mechanics. It occurs when the Sun, Earth, and Moon form a perfect (or nearly perfect) straight line in space.

Unlike a solar eclipse, which requires special glasses to view safely, a lunar eclipse is perfectly safe to observe with the naked eye. Here’s a step-by-step of what happens:

  1. The Penumbra: The event starts as the Moon moves into the Earth’s penumbra, its faint outer shadow. The dimming is very subtle and often hard to notice at first.
  2. The Umbra (Partial Phase): Things get exciting as the Moon begins to enter the umbra, the Earth’s central, dark, cone-shaped shadow. A dark, curved "bite" appears on the left side of the Moon, slowly growing larger.
  3. Totality: This is the grand finale. The Moon is entirely within the umbra. But why doesn't it disappear completely? It's because sunlight scatters through Earth's atmosphere. Our planet's sunrises and sunsets are projected onto the lunar surface. The shorter wavelengths of light (blues and greens) are scattered away, while the longer red and orange wavelengths bend around the Earth and illuminate the Moon. This is why a totally eclipsed moon is often called a "Blood Moon," and it can range in color from a coppery red and orange to a darker, rusty brown, depending on atmospheric conditions like volcanic dust or cloud cover.
  4. Reversal: After totality, the process reverses as the Moon slips out of the umbra and penumbra, returning to its full brilliance.

When and Where to Watch the September 2025 Lunar Eclipse


This lunar eclipse will be visible to a vast portion of the globe, offering millions a front-row seat to the cosmic ballet.

  • Prime Viewing Locations: Observers across Europe, Africa, Asia, and Australia will have the best views of the entire eclipse sequence. For those in the United Kingdom, Western Europe, and West Africa, the eclipse will be underway as the moon rises in the evening, a phenomenon known as a "selenelion," where you can see both the eclipsed moon and the setting sun simultaneously—a truly rare sight!
  • Partial Views: Viewers in eastern South America and parts of North America might catch the very end of the eclipse as the moon sets, but the full spectacle will be reserved for the Eastern Hemisphere.

Based on multiple astronomical sources, here are the UTC times for each phase of the total lunar eclipse on September 7, 2025:

  • Penumbral Eclipse Begins: 15:28:06 UTC (The Moon enters the Earth's faint outer shadow)
  • Partial Eclipse Begins: 16:26:51 UTC (The "bite" out of the Moon becomes visible)
  • Total Eclipse Begins: 17:30:36 UTC (The Moon is completely within Earth's umbra, turning red)
  • Maximum Eclipse: 18:11:43 UTC (The peak of totality)
  • Total Eclipse Ends: 18:53:18 UTC (The Moon begins to exit the darkest shadow)
  • Partial Eclipse Ends: 19:56:53 UTC
  • Penumbral Eclipse Ends: 20:55:27 UTC

The period of totality—the main event—lasts for a magnificent 82 minutes, giving us ample time to observe and capture the Moon’s transformation.
