“The Citadel”, one of the structures built by indigenous people who lived here from 500-1200 CE, provides a focus for a nighttime exposure. The Arizona skies are clear except for a cloud condensed by the contrasting air flows over the monument.

I had another camera in the sunflower field. This one faced south and caught the arcs of stars and planets near the ecliptic. Eventually the full moon entered the scene.

I have long been fascinated by sunflowers. On my travels across the prairies of the Dakotas I loved to encounter sunflower fields with their collective bright yellow heads all aimed in the same direction.
It is generally known that sunflowers track the sun across the sky, from east to west. I wondered what happens after sunset, when the flowers would all be facing west. With no phototropism to guide it, how would they get ready for the eastern sunrise? Would they be caught off-guard in the morning and suddenly swing their heads back at the risk of floral whiplash? Or is there a gradual re-setting of the neck-stalk fibers back to an easterly gaze?
A photogenic comet visits in a year when the world is shut down by a virus. We can still appreciate its beauty and find an isolated area in a nearby park. Photographing comets has become considerably easier in the twenty years since my previous attempts trying to capture Comet Hale-Bopp on film!

The Earth moves under the North Star while the moon illuminates the red rock canyon wall of Ayers Natural Bridges Park.
We were pleasantly surprised to discover this hidden gem in Wyoming, land donated from their ranch by the Ayres family. The park was entirely free, including campsites, but no pets are allowed. This is considered a benefit to some.

Amateur astronomers from around the country gathered at the observing facilities of the Minnesota Astronomical Society on a warm July evening. They discuss their observing plans for the night and wait in eager anticipation as the brighter planets start to appear in the fading twilight.

The moon rises over the cityscape of Minneapolis as its buildings start to turn on their own lighting.. This is the “supermoon”, a designation for when the moon is unusually close to Earth and hence, appears even larger than expected.

At 66 degrees north, Husavik Iceland is one degree away from the arctic circle. This places it directly beneath the usual position of the auroral oval, that zone of active energized atmosphere that creates the northern lights. The weather in Iceland is often overcast, but on this day the clouds cleared and the aurora were so brilliant they could be seen even over the lights of the city center and its active harbor.

The rosy glow of scattered twilight in the East is known as the “Belt of Venus”, which rides above the deep blue of Earth’s shadow on the sky. Here it is witnessed from the vantage of Hawaii’s tallest peak, Mauna Kea, as the world’s premier telescopes prepare for another evening of peering into the universe.
