Heavenly show to feature trifecta of super blue moon, eclipse

WASHINGTON (Reuters) – The moon will stage a rare triple show on Wednesday when a blue super moon combines with a total lunar eclipse that will be visible from western North America to eastern Asia, U.S. astronomers say.

The overlap of a blue moon – the second full moon in a calendar month – with a lunar eclipse while the moon is at its closest approach to the earth is the first such celestial trifecta since 1982, said Noah Petro, a research scientist at NASA’s Goddard Space Flight Center outside Washington.

“Just having these three things simultaneously occur is unusual,” Petro said in a telephone interview. “A blue moon is not extremely rare but it’s a nice coincidence that it happens in conjunction with these other two.”

The moon will reach its fullest on Wednesday at 8:27 a.m. EST (1327 GMT).

A blue moon normally occurs about once every 2-1/2 years. This month’s first full moon was on Jan. 1.

The blue moon also will be a super moon, which occurs when it is at or near its closest point to the earth, or perigee. A super moon is about 14 percent brighter than usual, the National Aeronautics and Space Administration said.

Wednesday’s moon will be the second closest of 2018 after the one on Jan. 1.

The lunar eclipse, which takes place when the moon passes in the earth’s shadow, will last almost 3-1/2 hours. It will start at 6:48 a.m. EST (1148 GMT) and peak at 8:29 a.m. EST (1329 GMT), NASA said.

The total eclipse will be visible from the western United States and Canada across the Pacific Ocean to most of Australia and China, as well as northern polar regions. The eclipse will give the moon a reddish color known as a blood moon.

“I’m calling it the purple eclipse because it combines the blue moon and a red eclipse,” Rich Talcott, a senior editor at Astronomy magazine, said by telephone.

Petro said the eclipse is also a scientific opportunity for researchers in Hawaii, who will study what happens to the moon’s surface when it quickly drops from 212 Fahrenheit (100 Celsius) in sunlight to minus 279 F (minus 153 C) in darkness.

The speed of cooling can show what the surface is made of, such as rock or dust, he said.

Super Moon To grace Earth’s Skies in coming days

CAPE CANAVERAL, Fla. (Reuters) – The largest, brightest full moon in nearly seven decades will be on display in the coming days, promising Earth-bound sky-watchers a celestial “supermoon” spectacle.

The full moon will come nearer to Earth than at any time since 1948, astronomers said. At closest approach, which occurs at 6:23 a.m. EST on Monday, the moon will pass within 216,486 miles (348,400 km) of Earth’s surface, about 22,000 miles (35,400 km) closer than average, they added.

The moon’s distance from Earth varies because it is in an egg-shaped, not circular, orbit around the planet.

If skies are clear, the upcoming full moon will appear up to 14 percent bigger and 30 percent brighter than usual, making it what is called a supermoon, according to NASA. A supermoon occurs when the timing of a full moon overlaps with the point in the moon’s 28-day orbit that is closest to Earth. About every 14th full moon is a supermoon, said University of Wisconsin astronomer Jim Lattis.

The next time a full moon comes as close to Earth will be in 2034.

“If you could stack up full moons next to each other, there is clearly a difference,” Lattis said, but to a casual observer it is going to look very similar to a regular full moon.

Weather permitting, sky-watchers in North America and locations east of the International Dateline will have a better view on Sunday night since the moon will set less than three hours after closest approach on Monday.

“The difference in distance from one night to the next will be very subtle, so if it’s cloudy on Sunday, go out on Monday. Any time after sunset should be fine,” Noah Petro, deputy project scientist for NASA’s Lunar Reconnaissance Orbiter, said in a statement.
