It's an awe-inspiring celestial event that millions have been waiting for, for years... a total solar eclipse will move from Mexico, the United States and out across the Atlantic coast today.
More people will witness this total solar eclipse than at any other time in human history. The moon's shadow will trace a path across North America, over the homes of around 31 million people.
You can watch our full coverage tonight on Total Eclipse Live, with Yalda Hakim, from 7pm
