Never peer directly at the sun — even through clouds — at any time. The sun is so blindingly bright that, unless it’s completely blocked by the moon during a total solar eclipse, it can permanently damage your eyes. The eclipse happening today (May 9 for those east of the International Date Line; May 10 for those west of it) is essentially a partial eclipse in that the sun will not ever be completely covered by the moon. Instead, at mid-eclipse, a thin ring of the sun’s outer surface will appear in a circle around the silhouetted moon, to those standing along the eclipse path running through Australia and the Pacific Ocean. You will need to watch online or use a safe filter or projection technique, to view the May 9-10 solar eclipse.
