total lunar eclipse will take place today on July 27, 2018. The Moon will pass through the centre of the Earth’s shadow. This will be the first central lunar eclipse since June 15, 2011.

This will be the longest lunar eclipse of 21st century.

Since it will occur near the highest point, this eclipse will also be the longest complete lunar eclipse in the 21st century. the moon will be completely covered by Earth’s umbra for approximately 103 minutes.

This eclipse will be the second complete lunar eclipse in 2018, after the one in January. The eclipse will occur simultaneously with the perihelic opposition of Mars, a coincidence that happens once every 25,000 years.

Perihelic opposition of mars is the area where Mars is closest to the sun and particularly close to the earth.

A lunar eclipse take place when the Moon passes within Earth’s shadow. As the eclipse begins, Earth’s shadow first darkens the Moon slightly. Then, the shadow begins to cove part of the Moon, turning it into a dark red-brown color. The Moon appears to be reddish because of Rayleigh scattering ,it is the same effect that causes sunsets to appear reddish and the refraction of that light by Earth’s atmosphere into its umbra which is the darkest part of Earth’s shadow.

It will be completely visible over Eastern Africa, and Central Asia, seen rising over South America, Western Africa, and Europe, and setting over Eastern Asia, and Australia.

Unlike with solar eclipses, you need no special equipment to observe lunar eclipses. These events are safe to view directly with the naked eye, telescopes or binoculars.

The simulation shows the approximate appearance of the Moon passing through Earth’s shadow. The Moon’s brightness is exaggerated within the umbral shadow. The northern portion of the Moon was closest to the center of the shadow, making it darkest, and most red in appearance.

You can check out the eclipse online via live webcasts from Virtual Telescope and Slooh.

Enjoy the show 🙂
