The Perseid Meteor Shower is an annual meteor shower observed for at least 2,000 years. It peaked last Friday and was seen all over the sky with the best views happening in the Northern Hemisphere.
Perseids are associated with the comet Swift-Tuttle, which orbits the sun once every 133 years. Every August, the Earth will through a cloud of the comet's debris. These bits of ice and dust - most more than 1,000 years old - burn up in the Earth's atmosphere to create one of the best meteor showers of the year, NASA said.
This is what happened while you were sleeping.
