Explanation: What are those dark streaks in this composite image of a solar eclipse? They are reversed shadows of mountains at the edge of the Moon. The center image, captured from Xiamen, China, has the Moon's center directly in front of the Sun's center. The Moon, though, was too far from the Earth to completely block the entire Sun. Light that streamed around the edges of the Moon is called a ring of fire. Images at each end of the sequence show sunlight that streamed through lunar valleys. As the Moon moved further in front of the Sun, left to right, only the higher peaks on the Moon's perimeter could block sunlight. Therefore, the dark streaks are projected, distorted, reversed, and magnified shadows of mountains at the Moon's edge. Bright areas are called Baily's Beads. Only people in a narrow swath across Earth's Eastern Hemisphere were able to view this full annular solar eclipse in 2020. Next month, though, a narrow swath crossing both North and South America will be exposed to the next annular solar eclipse. And next April, a total solar eclipse will be visible across North America.

Is anyone else getting “2001: A Space Odyssey” vibes right now?
So the dark round circle isn’t the whole moon?
Those dark jagged streaks are also part of the moon?
Why is the total image oval?
Machinists will appreciate this...
That’s one strange pic. It might take a while for me to get my hands around what I’m seeing.

I’m hearing Johnny Cash Ring of Fire
Multiple images taken over a lime lapse. Moon is moving and the Earth is rotating.
First, it is an annular eclipse, so the center image shows the ring of sunlight around the moon. The image is a composite of multiple shots showing a few seconds on either side before the full ring appears and the few seconds after it ends. The inner crescents show where the last, tallest lunar mountain is blocking the full ring (or the first one that breaks the ring at the end). As you track outward more and more of the mountains are able to beak the edge.
thank you for explaining
Ok I understand now
thanks
