See the moon's shadow on Earth from the 'ring of fire' solar eclipse in amazing space views

A "ring of fire" solar eclipse crossed over Africa and Asia this weekend, and the view from space was spectacular.

A NASA astronaut living and working in space and a host of weather satellites all spotted the dramatic event as the moon's shadow passed over Earth's surface. Although the solar eclipse wasn't visible from North America, it did happen to coincide with the U.S. celebration of Father's Day on June 21.

"Super cool view of the Annular Solar Eclipse which passed by our starboard side as we flew over China this morning," NASA astronaut Chris Cassidy wrote on Twitter. "A pretty neat way to wake up on Father's Day morning! Hoping all of the dads in the world have a wonderful day!"

A "ring of fire" or annular eclipse occurs when the moon passes between the sun and Earth. But, unlike during a total solar eclipse, the moon isn't close enough to Earth to block out all of the sun's visible disk.

Instead, a thin ring of the sun's disk remains visible around the moon's shadow even at the midpoint of the eclipse, hence the phenomenon's nickname.

But from space, an annular eclipse appears very similar to a total solar eclipse, and astronauts and satellites can spot the phenomenon by looking for a round shadow dancing across Earth's surface.

That's precisely what Cassidy saw from his vantage point as one of five astronauts living and working on the International Space Station, where he arrived in April. At the time, the space station was passing about 250 miles (400 kilometers) above Earth's surface.

Other space views of the eclipse show a much higher-altitude recap of what occurred. Russia's Elektro-L No.2 weather satellite spotted an interplay of shadows during the event, for example.

The satellite, which launched in 2015 and is one of three identical monitoring stations, was orbiting at an altitude of 22,000 miles (36,000 km), according to a statement from the Russian space agency Roscosmos.

Other weather satellites got in on the eclipse-watching action as well. Japan's Himawari-8 satellite and Europe's Meteosat-8 each followed the moon's shadow across Asia and Africa.
