Millions of people in the western United States and Asia will watch the sun turn into a ‘ring of fire’ this weekend.
Shadows on the ground will also turn into crescents and ‘rings’ of light as moon covers as much as 94% of the sun this Sunday.
‘Because some of the sun is always exposed during the eclipse, ambient daylight won’t seem much different than usual. Instead, the event will reveal itself in the shadows. Look on the ground beneath leafy trees for crescent-shaped sunbeams and rings of light,’ says Nasa.
