July 27: Blood Moon Visible in Prague

The second total lunar eclipse of 2018 will be visible in large parts of Australia, Asia, Africa, Europe, and South America. Totality will last for 103 minutes, making it the longest eclipse of the 21st century.

The eclipse will start at 20:24 Prague time, but over the territory of the Czech Republic, the Moon will appear only by 20:47. 

What is the Blood Moon of July 27?

Unlike with solar eclipses, you need no special equipment to observe lunar eclipses. These latter events, which occur when the moon passes into Earth’s shadow, are safe to view directly with the naked eye, telescopes or binoculars.

The moon turns deep red or reddish brown during eclipses, instead of going completely dark. That’s because some of the sunlight going through Earth’s atmosphere is bent around the edge of our planet and falls onto the moon’s surface. Earth’s air also scatters more shorter-wavelength light (in colors such as green or blue); what’s left is the longer-wavelength, redder end of the spectrum.

When is the best time to see the 2018 total lunar eclipse?

We recommend going outside at different times throughout the night on July 27 to catch every stage of the eclipse. Those lucky enough to see the 2018 lunar eclipse could also be treated to a view of Mars and the Milky Way, which will be to the left of the moon. With the light of the moon blocked by earth’s shadow, it’s the perfect time to view stars and celestial bodies not often seen by the naked eye.
