Орион над горой Немрут на рассвете Orion Dawn Over Mount Nemrut

What's that in front of Orion? Forty kilometers north of Kahta, Turkey, lies Mount Nemrut, a mountain adorned with the fragments of vast statues built over 2000 years ago. The stone sculptures once...

Солнечная колонна над Северной Каролиной A Sun Pillar Over North Carolina

Have you ever seen a sun pillar? When the air is cold and the Sun is rising or setting, falling ice crystals can reflect sunlight and create an unusual column of light. Ice sometimes forms flat, six-sided shaped crystals as it falls from high-level clouds.

Зодиакальный свет над Нью-Мехико Zodiacal Light Over New Mexico

An unusual triangle of light is visible this time of year just before dawn. Once considered a false dawn, this triangle of light is actually Zodiacal Light, light reflected from interplanetary dust particles. The triangle is clearly visible in the above image taken from New Mexico, USA, in October.

150-см рефлектор The 60 inch Reflector

On the night of December 13, 1908, 100 years ago today, the 60-inch diameter reflecting telescope of Mount Wilson Observatory was first tested on the stars. It became the first successful large reflecting telescope.

Восход Луны над Ликской обсерваторией Lick Observatory Moonrise

As viewed from a well chosen location at sunset, October's gorgeous Full Moon rose behind Mount Hamilton, east of San Jose, California. Captured in this lovely telescopic view, historic Lick Observatory is perched on the mountain's 4,200 foot summit, observatory and rising Moon momentarily sharing the warm color of filtered sunlight.

В центре Млечного Пути At the Center of the Milky Way

At the center of our Milky Way Galaxy lies a supermassive black hole. Once a controversial claim, this conclusion is now solidly based on 16 years of observations that map the orbits of 28 stars very near the galactic center.

NGC 281 NGC 281

Look through the cosmic cloud cataloged as NGC 281 and it's almost easy to miss stars of the open cluster IC 1590. But, formed within the nebula, that cluster's young, massive stars ultimately power the pervasive nebular glow.

M45: звездное скопление Плеяды M45: The Pleiades Star Cluster

Perhaps the most famous star cluster on the sky, the Pleiades can be seen without binoculars from even the depths of a light-polluted city. Also known as the Seven Sisters and M45, the Pleiades is one of the brightest and closest open clusters.

Туманность  "Темная штучка" The Dark Doodad Nebula

What is that strange dark ribbon on the sky? When observing the great globular cluster NGC 4372, observers frequently take note of a strange dark streak nearly three degrees in length running near it. Unnamed, the streak, actually a long molecular cloud, has become known as the Dark Doodad Nebula.

Гало вокруг Луны A Halo Around the Moon

Have you ever seen a halo around the Moon? This fairly common sight occurs when high thin clouds containing millions of tiny ice crystals cover much of the sky. Each ice crystal acts like a miniature lens.
