This was one of the first pictures that Nasa published showing the Moon starting to move in between the Sun and the Earth. This was visible from the west coast of the US. It looks a bit like the Moon is 'taking a bite' out of the Sun.

In the moment just after a total solar eclipse has happened, the Sun will peek back around from behind the Moon, like it's doing here. This happens as the Moon continues to move around the Earth. This creates an amazing effect which is known as the diamond ring. You can see why! It's one of the impressive moments during a total solar eclipse.
It's safe to say that millions of people across the US won't be forgetting this once-in-a-lifetime moment for many years to come.
