There's a comet called NEOWISE visible in the night sky July 15-23! It won't be seen again for another 6,800 years! To find it, go outside after dark and look to the northwest, below the Big Dipper. (Stefan tells you how to find the Big Dipper in the second video on this page of the website.) It needs to be pretty dark outside for the comet to be visible, so make sure you don't have any outside lights on. If you have a pair of binoculars, they might help!
Stefan took this picture of Comet NEOWISE from the Observatory at Youth Haven in Michigan on July 16.
A comet is a chunk of dust and ice that orbits the sun. The planets in our solar system also orbit the sun, but most planets travel around the sun in a circular pattern. Comets have an orbit that is shaped more like an oval, and it can take thousands of years for them to complete one orbit.
