Millions watch Pacific 'ring of fire' eclipse

People from Tokyo in Japan to California in the United States held parties to watch the amazing sight. The eclipse happened because the moon was at its furthest point away from the sun and so didn't block out its 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 in 18 years. It's called an 'annular' eclipse because of the glowing outline, or 'ring of fire', that the sun gives to the moon. We won't be able to see another one until 2023. Remember than you should never look directly at the sun as it might cause damage to your eyes.
