When is the moon of blood? July will be the longest lunar eclipse of this century

The night of July 27 and the morning of July 28 – depending on your location – will see the longest total lunar eclipse of the 21st century, lasting 1 hour and 43 minutes, reported EarthSky.

Mars will also appear particularly large and bright in the sky that night as she approaches her closest approach to Earth for 15 years. If time permits, this will give sky watchers a superb view of the red planet next to a glowing moon.

The eclipse will be visible from the eastern hemisphere in particular – it's half of the planet that is home to Asia, Australia, New Zealand and a large part of Europe and Africa. Some places in the Western Hemisphere, including parts of South America, will also have a glimpse.

A lunar eclipse occurs when the moon passes through the shadow of the Earth. When the moon passes through the darkest area of ​​the Earth's shadow – the "shadow" – it becomes red-orange, hence the term "blood moon".

A partial eclipse occurs when the moon passes through the outer shadow of the Earth; his "twilight". You can see if your region will get a total eclipse, a partial eclipse, or no eclipse at all on this timeanddate.com map.

The eclipse will take place from 18:24. UTC (2 h 24 hrs) and 10.19 pm. UTC (6.24 pm ET). The event will begin with a partial eclipse until around 7:30 pm. UTC, before the heavens are honored with the particularly long total eclipse.
