These posters by Tyler Nordgren show the national parks, universities and sightseeing spots in the US where spectators can go to see today's solar eclipse.
Nordgren, an astronomer and artist, created the 31 posters to commemorate today's solar eclipse which ? over the course of 100 minutes ? will see 14 states submerged into up to two minutes of darkness in the middle of the day.

Each of the posters, designed for NASA, show visitors spots where they will be best able to see the event, as well as providing information on how to watch it safely.
Similar to other posters released by NASA, the Eclipse 2017 collection has a retro style, and Nordgren used bold colours and graphic lettering to advertise each viewpoint.

"My newest poster campaign continues this tradition of science education through art by highlighting where Americans can go to see the most spectacular astronomical event anyone can see with their own eyes," said Nordgren. Among the 31 posters are designs that advertise the solar eclipse in general, and others that show specific places for spectators to go, such as the Great Smoky Mountains National Park, San Francisco's Exploratorium and the Sun Valley in Idaho.

One design depicts a hiker stood on top of the Borah Peak, while another sees a man boating down the Obed Wild and Scenic River in Tennessee.
Others encourage spectators to observe safely by using the correct protective eyewear.
