A "ring of fire" solar eclipse is visible in the U.S. for the first time since 2017.

A "ring of fire" solar eclipse is visible in the U.S. for the first time since 2017. The event -- which occurs when the moon passes directly between the Earth and the sun, blocking the sun's light -- illuminated the sky shortly after 5 a.m. EDT Thursday. NASA began livestreaming the spectacle on its website in the early morning. The eclipse can be seen in northeastern North America and northern regions of Europe and Asia.
