@nasa : Don't Stare! How to Safely Watch Today's Partial Solar Eclipse: During the late afternoon today, a partial solar eclipse will be visible from much of North America before sundown. Partial eclipses occur when the moon blocks part of the sun from view. However, it is NEVER safe to look at the sun with the naked eye. A partial solar eclipse occurs when the moon obscures only part of the sun from Earth's view. Image Credit: T. Ruen #eclipse #solareclipse #nasa #sun #moon #science
