Nature photographers and other fans of planet Earth always look forward to the blue hour.

On November 17, just an hour before sunrise, this bright and colorful meteor flashed through clear predawn skies.

Tonight the Moon is young again, but this stunning image of a young Moon near the western horizon was taken just after sunset on October 10.

Not the Hubble Space Telescope's latest view of a distant planetary nebula, this illuminated cloud of gas and dust dazzled even casual U.S. west coast skygazers on October 7.

That's not a young crescent Moon poised above the hills along the western horizon at sunset.

Bright meteors and dark night skies made this year's Perseid meteor shower a great time for a weekend campout.

Mars is also known as The Red Planet, often seen with a reddish tinge in dark night skies.

At sunset look east not west. As Earth's dark shadow rises from the eastern horizon, faint and subtle colors will appear opposite the setting Sun.

Skies after the near-solstice sunset on June 17 are reflected in this calm lake.
