Stargazers are in for a treat Sunday when a super moon combines with a lunar eclipse for the first time since 1982.
The supermoon eclipse will last 1 hour and 11 minutes, and will be visible to North and South America, Europe, Africa, and parts of West Asia and the eastern Pacific, according to NASA. Although the full Eclipse will not be visible here in Vietnam the Super Moon will be.
A rare phenomenon, there have only been five supermoon eclipses since 1900 (in 1910, 1928, 1946, 1964 and 1982). After Sunday, the next supermoon eclipse will occur in 2033.
A supermoon occurs when a new or full moon is at its closest to the Earth. “Because the orbit of the moon is not a perfect circle, the moon is sometimes closer to the Earth than at other times during its orbit,” said Noah Petro, deputy project scientist for the Lunar Reconnaissance Orbiter at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement. “When the moon is farthest away it’s known as apogee, and when it’s closest it’s known as perigee. On Sept. 27, we’re going to have a perigee full moon—the closest full moon of the year.”

Lunar eclipses have long been a source of fascination.
“Throughout human history, lunar eclipses have been viewed with awe and sometimes fear,” explained NASA, in a statement. “Today, we know that a total lunar eclipse happens when the full moon passes through the darkest part of Earth’s shadow, the umbra.”
