Crescent Venus and Moon
29.10.2006

There's something behind these clouds. Those faint graceful arcs, upon inspection, are actually far, far in the distance. They are the Earth's Moon and the planet Venus. Both the Moon and Venus are bright enough to be seen during the day, and both are quite capable of showing a crescent phase.

A Kalahari Sky
29.05.2017

You wake up in the Kalahari Desert in Botswana, Africa. You go outside your tent, set up your camera, and take long exposures of the land and sky. What might you see? Besides a lot of blowing dust and the occasional acacia tree, you might catch many sky wonders.

Hideaway
20.06.2006

Is this a picture of a sunset from Earth's North Pole? Regardless of urban legends circulating the Internet, the answer is no. The above scene was drawn to be an imaginary celestial place that would be calm and peaceful, and therefore titled Hideaway.

Iridescent by Moonlight
3.12.2021

In this snapshot from November 18, the Full Moon was not far from Earth's shadow. In skies over Sicily the brightest lunar phase was eclipsed by passing clouds though. The full moonlight was dimmed and momentarily diffracted by small but similar sized water droplets near the edges of the high thin clouds.

A View from Earth s Shadow
19.05.2022

This serene sand and skyscape finds the Dune of Pilat on the coast of France still in Earth's shadow during the early morning hours of May 16. Extending into space, the planet's dark umbral shadow covered the Moon on that date.

The Comet and the Galaxy
13.03.1999

The Moon almost ruined this photograph. During late March and early April 1997, Comet Hale-Bopp passed nearly in front of the Andromeda Galaxy. Here the Great Comet of 1997 and the Great Galaxy in Andromeda were photographed together on 1997 March 24th. The problem was the brightness of the Moon.

A Moon Dressed Like Saturn
15.03.2020

Why does Saturn appear so big? It doesn't -- what is pictured are foreground clouds on Earth crossing in front of the Moon. The Moon shows a slight crescent phase with most of its surface visible by reflected Earthlight known as ashen glow.

Noctilucent Clouds
15.06.2003

Sometimes it's night on the ground but day in the air. As the Earth rotates to eclipse the Sun, sunset rises up from the ground. Therefore, at sunset on the ground, sunlight still shines on clouds above.

The Belt of Venus
8.12.2001

Although you've surely seen it, you might not have noticed it. During a cloudless twilight, just before sunrise or after sunset, part of the atmosphere above the horizon appears slightly off-color, slightly pink.
