このコンテンツについて
An annular solar eclipse happens when the Moon passes between the Earth and the Sun, but is at or near its farthest point from Earth. This means the Moon appears smaller than the Sun and doesn't completely cover it, creating a "ring of fire" effect.
On June 10, 2021, this celestial spectacle was visible from parts of Canada, Greenland, and Russia. The path of annularity - where the "ring of fire" was visible - stretched from northern Ontario, across Greenland, the North Pole, and ended in northeastern Siberia.
Imagine the excitement of astronomers and sky-watchers as they gathered in these remote locations, bundled up against the cold, their specialized cameras and telescopes at the ready. As the Moon slowly moved across the face of the Sun, a collective gasp could be heard as the "ring of fire" formed - a brilliant circle of sunlight surrounding the dark disk of the Moon.
This event wasn't just beautiful; it was also scientifically valuable. Solar eclipses provide rare opportunities for scientists to study the Sun's corona, or outer atmosphere, which is usually obscured by the intense light of the photosphere.
For those outside the path of annularity, a partial solar eclipse was visible from much of the Northern Hemisphere, including parts of Europe and Asia. Even a partial eclipse is a remarkable sight, with the Moon taking a "bite" out of the Sun's disk.
So while you're living in 2025, take a moment to remember this spectacular event from a few years ago. And who knows? Maybe you're looking forward to the next annular solar eclipse, which will occur on June 1, 2030. Mark your calendars, future astronomers!
