Total Lunar Eclipse (Blood Moon) — What to Know, When & Where to Watch
What is a “Blood Moon” (Total Lunar Eclipse)?
A Blood Moon is the popular name for a total lunar eclipse, when Earth moves directly between the Sun and the Moon and casts its shadow across the lunar surface. During totality the Moon can turn a dramatic coppery-red color because sunlight passing through Earth's atmosphere is refracted and scatters blue light — leaving red and orange wavelengths to reach the Moon. This natural phenomenon is safe to view with the naked eye and has fascinated skywatchers for centuries.
Next major event & visibility
The next widely reported total lunar eclipse (often called a Blood Moon) falls on September 7–8, 2025. This particular event will be well-seen across large parts of Asia, Europe, Australia and Africa. Much of the continental United States will not have direct nighttime viewing for this occurrence; however, U.S. viewers can often watch high-quality livestreams from observatories and virtual telescope projects.
Why the Moon turns red
When sunlight passes tangentially through Earth's atmosphere, shorter wavelengths (blue) are scattered away while longer wavelengths (red/orange) are bent toward the Moon. The result is the deep reddish hue familiar from many eclipse photographs.
How to watch (Visibility, times & livestreams)
If you are inside the eclipse's visibility region you can simply step outside and watch — no protective eyewear required for lunar eclipses. If you're outside the viewing region, look for reputable livestreams from NASA, major planetariums or dedicated projects such as the Virtual Telescope Project.
Local timing
Eclipse timing varies by longitude. Check a reliable local source (astronomy sites and time zone calculators) for exact contact times in your city. Many astronomy outlets publish start-to-end times in UTC and in common timezones to make it easy to convert.
Photography & viewing tips
- Camera gear: A DSLR or mirrorless camera with a telephoto lens (200mm+) will capture lunar detail. For dramatic wide shots include a foreground subject (landscape, building, tree).
- Settings: Start around ISO 200–800, aperture f/5.6–f/8 and shutter speeds from 1/125s (during partial phases) to 1–2s (during deepest totality) — bracket as conditions and gear vary.
- Stability: Use a sturdy tripod and remote shutter or intervalometer to avoid camera shake.
- Apps: Use an astronomy app to find rise/set & contact times and plan a composition.
Myths & culture
Across cultures lunar eclipses have inspired myths and stories — from animals or dragons "eating" the moon to symbolic interpretations in astrology and folklore. While intriguing, these are cultural layers added on top of the well-understood astronomical mechanics.
Safety & accessibility
Unlike solar eclipses, a lunar eclipse poses no risk to your eyes — it is always safe to look directly at the Moon during a lunar eclipse. If you or your viewers cannot go outside, prioritize live broadcasts and captioned video options for accessibility.
