Utah's Rainbow Bridge National Monument Becomes World's Fourth International Dark Sky Sanctuary

Zitat

At a Glance

Utah's Rainbow Bridge National Monument is one of the darkest, most remote places on Earth with light-pollution-free views of the night sky.

It becomes the fourth dark-sky sanctuary in the world, as named by the International Dark-Sky Association.

Cosmic Campground in western New Mexico's Gila National Forest is another IDA sanctuary.


Utah's Rainbow Bridge National Monument has been named the fourth international dark sky sanctuary in the world, distinguishing it as one of the darkest, most remote places on Earth with unparalleled, light-pollution-free views of the night sky.
The United States National Parks Service and the International Dark-Sky Association (IDA) announced the designation last week in a joint press release, noting the quality of the 160-acre site's "naturally dark night skies" and cultural heritage, according to a press release.
“This designation is an important step to ensure we protect the entirety of the landscape at Rainbow Bridge National Monument, which is sacred to many of the Native American Tribes in the area,” said William Shott, Superintendent of Rainbow Bridge National Monument and Glen Canyon National Recreation Area. “We’re thrilled to be the first National Park Service unit to receive this specific designation, as this will only fuel our night sky preservation efforts.”

'Fire rainbow' spotted over Pinnacles National Park in California

Zitat

A runner spotted a “fire rainbow” over Pinnacles National Park in California, the National Weather Service, Bay Area announced on Wednesday.
A fire rainbow, more formally known as a circumhorizontal arc, occurs when the sun is more than 58 degrees above the horizon. The sun must be higher than this in order for the arc to form, according to Atmospheric Optics.
Then, as the sun’s light is refracted off of the ice crystals in cirrus clouds, “you get pretty colors,” Roger Gass, a meteorologist with the National Weather Service (NWS), told SFGate.
"It's an optical illusion,” he added.
If you live in North America, you have a good chance of seeing the phenomena, especially during the summer months. In fact, depending on where you live in the states, a fire rainbow can be spotted five or more times during the summer, according to Atmospheric Optics.
Fire rainbows are extremely uncommon in Northern Europe, however, and are “impossible to see north of Copenhagen,” the weather site says.
