A "ring of fire" solar eclipse appeared in the sky.
Visible in parts of the Northern Hemisphere, it's the first of two solar eclipses this year. A solar eclipse happens when the moon crosses between the sun and the Earth, which blocks a portion of the sun's rays, but in an annular eclipse, the moon is far enough away from the Earth that it appears smaller than the sun. When the moon crosses paths, it will leave room for bright light to glow around the edges. This is called "the ring of fire" and was visible to some people in Greenland, northern Russia and Canada.
For those unable to see the eclipse, NASA and The Virtual Telescope Project streamed live views.
The name "annular" comes from the Latin word "annulus," which means ring-shaped.
