The full moon should slide through the Earth's shadow on July 27 to create a beautifully red total lunar eclipse for one hour and 43 minutes. It is the longest eclipse of the young century.

Here in the United States, we are on the wrong side of the world to see it locally. But thanks to Internet magic, Americans can watch it live on the Weather Channel application (their show starts at 4pm) or on the Slooh.com website (their members can start watching at 1pm) or on Time and Date. com from 2pm Simone Boyce, NBC News' new streaming network host, will be the anchor of the digital special "Space is Awesome" – timed for the lunar eclipse.

The people of West Africa, parts of Europe, the Middle East and India will only have one. looking at the sky to capture in person the deepest depth of the copper

Lunar eclipses occur only during the full moon, which means that the moon and the sun are on opposite sides of the Earth. In this case, the full moon officially occurs at 4:20 pm. The Earth casts a shadow at the opposite of the sun – and the moon can sometimes traverse the shadow. As the moon pbades through the shadow, the light refracted by the Earth gives the moon a reddish hue.

According to NASA and the US Naval Observatory, the lunar eclipse (penumbral phase) begins at 1:14 pm. and the bias occurs at 2:24 pm. The totality starts at 15:30 and the totality at 16:21. The totality ends at 17:13 and the partial eclipse ends at 18:19. Everything is finished before 19h28. Unfortunately, the moon has not risen anywhere in the United States to be watched during this window.

But it will make a great show elsewhere

"What makes the next special, is that it occurs almost at the same time as the second lunar climax of the year (the monthly moment when the moon is farthest away from Earth) and the moon pbades almost in the center of the Earth 's shadow, "Geoff Chester astronomer of the Naval Observatory said. He continued: "This will make it the longest total lunar eclipse of the century.It is as cool as [the eclipse] occurs the night when Mars reaches the opposition, so (for people on the other side of the world) you will have a red moon six degrees north of the red planet. "

Indeed, the planet Mars will be opposite – opposite to the sun in the night sky of the Earth – but close to the moon on the 27th July. Mars rises at sunset and sets at sunrise, according to Chester

All eclipses belong to families of eclipses called saros. In this case, this eclipse is part of Saros 139, and it is the No. 38 in a family of 71 that began on June 10, 1351. This saros will last until July 24, 2613, by NASA. Although technically, this is the longest eclipse of the current century, the two previous lunar eclipses of this series – July 16, 2000 (No. 37, Saros 139) and July 6, 1982 (No. 36, Saros 139) – lasted longer. long

In fact, the lunar eclipse of July 16, 2000 lasted about three minutes longer. But remember, astronomers count the year 2000 as a part of the last century.

Babies and young children of today can catch the shortest total lunar eclipse in this saros. It will arrive on September 8, 2090. There will be only 32 minutes of total in this eclipse.

While the United States will not see this total lunar eclipse live, in six months, be sure to have mittens. , a coat and a hot chocolate with marshmallows ready. There will be a total lunar eclipse on January 20th and 21st. The reddish total will last a delicious 62 minutes. For that one, Chester of the Naval Observatory says, "we will have a place at the forefront for all event."
