Millions living around the Pacific Ocean watched the 'ring of fire' eclipse on Sunday and Monday morning.
People from Tokyo in Japan to California in the United States held parties to watch the amazing sight.
It happened because the Moon was at its furthest point from the Earth, so it didn't block the Sun's rays completely when it passed in front of it.
It's pretty rare to see this type of eclipse. This is the first one seen in the US for 18 years.
It's called an 'annular' eclipse because of the glowing outline, or 'ring of fire', that the Sun gives to the Moon.
The three types of eclipse
There are three different kinds of eclipse - total, partial and annular.
A total eclipse is when moon fully covers the sun - this happens somewhere in the world about once a year.
A partial eclipse is when Moon appears to cover just part of the Sun.
Annular eclipses are the rarest - they happen about once every couple of years.
The last eclipse that was visible in the UK was back in 1999.
Remember than you should never look directly at the Sun, as it might cause damage to your eyes.
