Do not miss to watch the longest blood moon or longest total lunar eclipse on July 27, 2018. The total phase of the “blood moon” eclipse that will happen in a two weeks, is supposed to be last 1 hour and 43 minutes, during which Earth’s natural satellite will turn a spectacular red or ruddy-brown color. From start to finish, the entire celestial event will last nearly 4 hours.
People in North America do not have a chance to watch eclipse, except via webcasts. “But observers in much of Africa, the Middle East, southern Asia and the Indian Ocean region will get an eyeful, given cooperative weather, according to lunar scientist Noah Petro, of NASA’s Goddard Space Flight Center in Greenbelt, Maryland”, informed space.com.
Blood moon happens on the same day the planet Mars reaches its opposition, when it will shine at its best in the night sky. From 2003 Mars has not been so close to Earth, and this month this unique phenomenon will happen. After opposition, when Mars will be brightest, it reaches that closest point on July 31.
From Where May You Watch the Eclipse?
The eclipse will be visible from eastern South America as it is ending, and from Australia as it is beginning. The entire eclipse you may witness from Africa, the Middle East and countries in central Asia. And as we have mentioned above it won’t be visible from North America.
When Will It Be Visible?
The time of greatest eclipse will be 4:21 p.m. EDT (2021 GMT) on July 27. The total eclipse will last from 3:30 p.m. to 5:13 p.m. EDT (1930 to 2113 GMT). There will also be some time before and after when the moon is in the lighter part of Earth’s shadow, which is called the penumbra. Including that penumbral time, the eclipse will last for 3 hours and 55 minutes, according to space.com.
And Why the Eclipse Is Considered to Be the Longest One?
“What controls the duration of the lunar eclipse is the position of the moon as it passes through the Earth’s shadow,” Petro told Space.com. The darkest part of Earth’s shadow is called the umbra. You can picture the umbra as a cone extending from Earth in the opposite direction to the sun, Petro explained. “The moon can either graze through the cone, or go right through the middle. That [the middle] gets a longer-duration eclipse,” he said. “This time, the moon is passing closer to the center of that cone, and it’s therefore a little bit longer than the eclipse we had back in January.”
