The “stars” of a new 3-minute timelapse are some very unique star trails and a glowing fireball that is actually a giant ‘honey moon‘ — the full Moon in June. Gavin Heffernan from Sunchaser Pictures and Harun Mehmedinovic from Bloodhoney.com teamed up for this video, filming in gorgeous mountain locations in the Southwestern US, showcasing gathering storm clouds and stunning night sky scenes.
At about 1:50 in the video, you’ll see a unique “split” star trail effect, where it looks like the trails are cascading down the sides of a mountain. At 2:02, the Moon appears to burn through the sky like a meteor.
See imagery from the footage below:
This video is part of the Skyglow Project, which is an initiative to protect the night skies and raise awareness of the light pollution and its dangers. It was produced in association with BBC Earth.
Interestingly, Heffernan said some of the footage seen here was also featured this summer by The Rolling Stones in their Zip Code Stadium Tour, after Mick Jagger saw some of their previous timelapse videos.
The footage was shot in Monument Valley, Arizona, Trona Pinnacles, California, and Red Rock Canyon, California.
Thanks to Gavin Heffernan for continuing to share his wonderful work!

Between the years of 1969 and 1972 the astronauts of the Apollo missions personally explored the alien landscape of the lunar surface, shuffling, bounding, digging, and roving across six sites on the Moon. In order to prepare for their off-world adventures though, they needed to practice extensively here on Earth so they would be ready to execute the long laundry lists of activities they were required to accomplish during their lunar EVAs. But where on Earth could they find the type of landscape that resembles the Moon’s rugged, dusty, and — most importantly — cratered terrain?
Enter the Cinder Lakes Crater Fields of Flagstaff, Arizona.
The Cinder Lakes Crater Fields northeast of Flagstaff, near the famous San Francisco peaks and just south of the Sunset Crater volcano, were used for Apollo-era training because of the inherently lunar-like volcanic landscape. LRV practice as well as hand tool geology and lunar morphology training were performed there, as well as ALSEP – Apollo Lunar Surface Experiment Package – placement and setup practice.
The photo above shows Apollo 15 astronauts Dave Scott and Jim Irwin driving a test LRV nicknamed Grover along the rim of a small “lunar crater.” (This particular exercise was performed on Nov. 2, 1970… 44 years ago today!)

Although the craters might look similar to the ones found on the Moon, they were actually created by the USGS in 1967 by digging holes and filling them with various amounts of explosives, which were detonated to simulate different-sized lunar impact craters. The human-made craters ranged in size from 5-40 feet (1.5-12 meters) in diameter.
The two crater field sites at Cinder Lakes were chosen because of the specific surface geology: a layer of basaltic cinders covering clay beds, left over from an eruption of the Sunset Crater volcano 950 years ago. After the explosions the excavated lighter clay material spread out from the blast craters and across the fields, like ejecta from actual meteorite impacts. A total of 497 craters were made within two sites comprising 2,000 square feet.
Detonations were done in series to simulate ejected debris from cratering events of different ages. And one of the areas of Cinder Lakes was designed to specifically replicate craters found within a particular region of the Apollo 11 Mare Tranquillitatis landing site.

Today only the largest craters can be distinguished at all in the publicly-accessible Cinder Lakes field, which has become popular with ATV enthusiasts. But a smaller field, fenced off to vehicles, still contains many of the original craters used by Apollo astronauts, softened by time and weather but still visible.
A couple of other areas were used as lunar analogue training fields as well, such as the nearby Merriam Crater and Black Canyon fields — the latter of which is now covered by a housing development. Geology field training exercises by Apollo astronauts were also performed at locations in Texas, New Mexico, Nevada, Oregon, Alaska, Idaho, Iceland, Mexico, the Grand Canyon, and the lava fields of Hawaii. But only in Arizona were actual craters made to specifically simulate the Moon!

As the Milky Way now begins to set earlier in the evening here in the northern hemisphere, that doesn’t mean the photos of our night sky are any less stunning. This lovely shot for #TerrestrialTuesday by photographer Jack Fusco was taken this week at Horseshoe Bend in Arizona, a horseshoe-shaped meander of the Colorado River.
“During the day, the walk to Horseshoe Bend was full of tourists from all over the world,” Jack explained on Flickr. “At night, we sat alone and stared up at a brilliant star filled sky and only heard coyotes in the distance. It was an absolutely incredible location during the day and at night. This was shot with no Moon at the sky, so the area was at it’s absolute darkest. I was a little nervous setting up my gear for this shot as my tripod was just a few inches from a 1000ft drop down to the river. It was certainly an experience I’ll never forget.”
