The total lunar eclipse this week is the longest of the century



The full moon will glide through the Earth's shadow on July 27 to create a beautiful red total lunar eclipse for an hour and 43 minutes. This 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 app (the show starts at 4pm) or on the Slooh website (members can watch at 1pm) or watch TimeandDate.com from 2pm on Simone Boyce, new presenter of the NBC news streaming network, will anchor the digital special "Space Is Awesome" – timed to the lunar eclipse. Find the program on NBCNews.com at 16.00. July 27th.

People in West Africa, parts of Europe, the Middle East and India will only have to look up to see the copper-colored totality in person.

Lunar eclipses occur only during a 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 16:20. Eastern time on the 27th of July. The earth casts a shadow over the sun – and the moon can occasionally run through the shadows. As the moon slips through the shadows, the light refracted by the earth gives the moon a reddish hue.

According to NASA and the US Naval Observatory, the lunar eclipse begins at 1:14 pm throughout the Eastern Time Zone. and partiality occurs at 2:24. Totality starts at 3:30, with the maximum total at 16:21. The totality ends at 17:13 and the partial eclipse ends at 18:19. Everything is finished at 19:28. Unfortunately, the moon has not risen anywhere in the United States to be seen during this window.

But it will show a great show elsewhere.

"What makes it special is that it takes place almost at the same time as the second highest lunar lunar of the year (the monthly moment when the moon is farthest from Earth) and the moon is almost sliding through the center of the earth Shadow, "said astronomer Geoff Chester of the Naval Observatory. He continued, "This will make it the longest total lunar eclipse of the century, and it's also cool that [the eclipse] occurs in the night that Mars reaches the opposition, so (for people on the other side of the world) A red moon six degrees north of the Red Planet. "

In fact The planet Mars will be in opposition to the sun in the night sky of the earth, but close to the moon on July 27. Mars rises at sunset and sets at sunrise, according to Chester.

All eclipses belong to solar eclipse families. In this case, this solar eclipse is part of Saros 139, and she is No. 38 in a family of 71 that began on June 10, 1351. These saros will last until 24 July 2613 per NASA. While this will technically be the longest eclipse of the century, the two previous lunar eclipses in this series – July 16, 2000 (# 37, Saros 139) and July 6, 1982 (# 36, Saros 139) – lasted longer than this.

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

Todays babies and toddlers can observe the shortest total lunar eclipse in this saros. It comes on September 8, 2090. There will be only about 32 minutes of totality in this solar eclipse.

While the United States will not experience this total lunar eclipse live, in six months make sure you have gloves, a coat and hot chocolate with marshmallows ready. There will be a total lunar eclipse between January 20th and 21st. The reddish totality will take 62 minutes. Chester says, "We'll have a seat in the front row for the whole event."
