Guest contributor Matthew Hibbard investigates why the stars over Utah's Bryce Canyon National Park are dimming.
Tens of thousands of visitors flock each year to Bryce Canyon to admire the stars.
Light pollution over the National Park is a growing menace for skywatchers.
Educating the public about light pollution is one program park rangers are spearheading.
Bryce Canyon National Park is known for its unique geology and sprawling landscape. During the Ice Age, glaciers sliced through the red stone, leaving behind odd shapes and beautiful scenery. But the park's beauty doesn't disappear once the sun sets. In fact, it lights up.
Ever since 1969, Bryce Canyon has been hosting star programs for public visitors and amateur astronomers. This year, more than 37,000 visitors have participated in 100 different star presentations offered at the park.
Dark Ranger Kevin Poe believes recent events in space, such as the shuttle mission to fix the Hubble Space Telescope, have brought more people to the park. Poe also says visitors are noticing that the stars above aren't shining as brightly as they used to.
