The edge of the sun is visible around the silhouette of the moon during an eclipse, forming a burning ring behind a veil of thin clouds.

1 week until an annular solar eclipse turns the sun into a ‘ring of fire’ over Antarctica on Feb. 17

February 10, 2026

We’re just one week away from the first solar eclipse of 2026! Here’s what you need to know before a dramatic “ring of fire” annular eclipse darkens the sky over Antarctica on Feb. 17, likely confusing millions of penguins.

The eerie dimming is possible thanks to an extraordinary bit of celestial geometry. Earth’s moon is 400 times smaller than the sun, which happens to be, on average, 400 times farther from our planet than its natural satellite — a wondrous cosmic coincidence that causes both celestial objects to appear the same size in our sky.

This allows us to see breathtaking solar eclipses when the lunar disk passes directly in front of the sun during its new moon phase, blocking its light. Some eclipses occur when the moon is further from Earth in its elliptical orbit, setting the stage for a spectacular annular solar eclipse. During these events, the smaller lunar disk passes in front of the sun, occulting most of its surface, while leaving a sliver of its outer rim on show.

Feb. 17 will see a spectacular annular solar eclipse unfold over a swathe of Antarctica, as the moon glides between the sun and Earth, occulting the vast majority of our parent star while leaving its outer rim visible to form a burning halo in the southern sky.

The period of maximum eclipse — an event known as annularity — is set to begin at 7:12 a.m. EST (1212 GMT) and will last for 1 minute and 52 seconds, after which the moon’s silhouette will slide inexorably off the solar disk.

Sadly, the full ring of fire will only be witnessed by the few human beings inhabiting research stations in the path of annularity, along with the millions of penguins who call the frozen continent home. Skywatchers in the southern extreme of South America, southeastern Africa and in parts of the Pacific, Atlantic and Indian Ocean will also bear witness to a lesser— yet still breathtaking — partial solar eclipse, during which the lunar disk will be seen to take a “bite” out of the sun.

observe the sun safely, you’ll need a pair of eclipse glasses designed to block out the lion’s share of the harmful ultraviolet and infrared solar radiation, or — for a closer look — a pair of dedicated solar binoculars, like the Lunt SUNoculars and Celestron Eclipsmart. And with the upcoming total solar eclipse coming on Aug. 12, it’s never too early to get all your solar viewing equipment ready!
