Basic astronomy and night sky information
Beautiful and interesting images and video of the night sky including stars, planets, the Milky Way, and deep-sky objects taken through a camera lens or through a telescope.
“What good is the warmth of summer, without the cold of winter to give it sweetness.”
― John Steinbeck

After a cloudy night, the sky cleared as dawn arrived on a late summer morning as seen from Bruneau Dunes State Park in southern Idaho on September 8, 2018. Here you see a very slender waning crescent Moon to the upper left of the star Regulus. Mercury is at the lower middle of this image, just above the clouds. Just minutes earlier, the constellation Orion tried to peak through the early-morning clouds (see below) [Read more…] about Dawn Sky – Crescent Moon, Mercury, Regulus, and Orion

The folks at NASA Goddard in Greenbelt, MD, have put together a glorious video of an accelerated sunrise and sunset on the Moon that will reward you with some of the finest images ever taken of our nearest neighbor, and perhaps inspire you to see some of these features with your own telescope. NASA set this visualization of sunrises and sunsets on the Moon to the strains of Claude Debussy’s most famous work, Clair de Lune. Watch the whole thing. It’s a great way to spend a few minutes.

The outer rim of the Milky Way as seen in late summer towards the constellations Cassiopeia and Perseus.
“Peer at things up close and you may learn their true form
but guessed at from afar, they seem like something else.
Vastness such as this is beyond comprehension:
all I can do is sigh in endless wonder”. – Su Tung-P’o (1060 A.D.)
An abandoned sailboat in a grassy field in northern Virginia makes for a good, if unexpected, foreground for this image of the summer Milky Way. Mars is at lower left, while Saturn is below center, and just below the airplane trail. The silvery rectangle of stars above the plane trail is the Small Sagittarius Star Cloud (Messier 24). Many pink nebulae and silver-gray star clusters fleck the trail of the Milky Way. Look to the upper left of the image to see the little upside-down ‘Coat Hanger’ asterism known as Collinder 399.
Image taken on July 8, 2018 near Warrenton, VA, with a Nikon D750 and Tamron 15-30mm lens at f/2.8, a NiSi natural night filter, ISO 3200, 20 seconds.
