Discard solar eclipse glasses from 2017. They're likely expired. The 2012 annular solar eclipse left the telltale "ring of fire" that will be visible in parts of Canada, Greenland and Russia on June 10, 2021. (Image credit: Phillip Jones/Stocktrek Images via Getty Images) The moon will blot out part of the sun during the "ring of fire" solar eclipse on Thursday (June 10) morning. But, no one should simply gaze upward at a solar eclipse (unless the sun is completely covered by the moon during totality, which is NOT happening this time). So, what's a skygazer to do? Depending on where you are, you'll be able to see the solar eclipse either in person — weather and gear permitting — or online with live streams.
