Super blue blood moon: Stunning pictures show the celestial event not seen for decades

Stunning photos of the “super blue blood moon” have flooded in from across the world.

The celestial event – a combination of three rare lunar phenomena – has been captured by people in America and Asia who were able to see the stunning sight.

The “blood moon” is another name for a lunar eclipse. That describes when the Earth moves between the sun and the moon, and as the light comes around our planet it is turned a deep red that then shows on the face of the lunar surface, giving the effect its name.

The supermoon refers to times when the full moon also lines up with its perigee – the point in its orbit when it’s closest to the Earth. That makes it look big and bright.

Together, the phenomenon was a stunning one: a big, bright, bloody moon lighting up the night sky. The latest pictures show what experiencing it was like.

The blue moon, which occurs when a full moon happens twice in one calendar month, can’t actually be seen.

As well as making for a stunning sight, the lunar eclipse allowed Nasa to learn more about the moon’s surface. When the light is blocked out, the surface goes very cold – by studying the effects of that, scientists can learn more about what the moon’s still mysterious surface is made out of.

At the Griffith Observatory in Los Angeles, hundreds gathered on the lawn in the wee hours under clear skies. Traffic was backed up more than a mile around the observatory. Sky-gazers also lined the beach near the Santa Monica Pier, some snapping photos and others reclining in the sand, their faces turned upward.

John Cook joined fellow photography enthusiasts at the pier, using the ferris wheel and roller coaster for his foreground.

"It was incredible," said Cook, a visual effects artist for films. Photographers also gathered at the Telegraph Hill neighborhood of San Francisco, striving to get the famous Coit Tower in their moon shots.

In San Francisco's Marina district, a crowd gathered to watch the super blue blood moon, as NASA calls it, set over the Golden Gate Bridge. Spectators got lucky: There were clear skies and no trace of the city's famous fog.

"It's very cinematic, the way the moon is changing colors and reflecting on the water," said Clara Cambon, who arrived around 5:30 a.m. with her husband.

On the other side of the Pacific, where it was already nightfall, hundreds descended on the Tokyo Garden Terrace Kioicho complex, where telescopes and binoculars were plentiful. A TV monitor showed zoom-in views of the moon, and a university professor gave a run-down as the eclipse unfolded.

"It's wonderful to be at this precious event and to have been able to see the moon looking so beautiful," said Mayumi Kimura, a visitor.

The U.S. East Coast, Europe and most of South America and Africa were out of luck for the total eclipse. At Cape Canaveral, Florida, where a rocket delivered America's first satellite to orbit exactly 60 years ago — Explorer 1 — the blue super moonloomed large in the sky.

The second full moon in a calendar month is a blue moon. This one also happened to be an especially close and bright moon, or supermoon. Add a total eclipse, known as a blood moon for its red tint, and it was a lunar showstopper.

NASA called it a lunar trifecta: the first super blue blood moon since 1982. That combination won't happen again until 2037. For those looking ahead, the next supermoon is in February, the next blue moon is in March and the next total lunar eclipse is in July, according to NASA.

NASA lunar scientist Noah Petro said he was astonished — and thrilled — by all the attention and fuss. The total solar eclipse that swept across the U.S. in August contributed to Wednesday's buzz, he noted. Missing out on the eclipse from his home in Virginia, he watched the event online Wednesday morning with his two children, ages 3 and 7.

"I hope that people use this as an opportunity to dig in a little more and learn about our own planet, our wonderful sister planet, the moon, and the sun and all the other great objects in the solar system," Petro said on his way to work at Goddard Space Flight Center in Greenbelt, Maryland.

A total lunar eclipse — considered the most scientific of Wednesday's threesome — occurs when the sun, Earth and moon line up perfectly, casting Earth's shadow on the moon.

Scientists were keen to study the sharp, sudden drop in temperature at the lunar surface as Earth's shadow blankets the moon. During the more than one hour of totality, the temperature plunged 100 degrees Fahrenheit (38 Celsius), said Petro. He's deputy project scientist for NASA's Lunar Reconnaissance Orbiter, circling the moon since 2009. His team took special precautions to keep the spacecraft warm during the eclipse.

For the trivia crowd, the moon was 223,820 miles (360,200 kilometers) away at the peak of the eclipse, close enough for supermoon status, according to NASA.
