Линзообразное облако над Новой Зеландией A Lenticular Cloud Over New Zealand

What's happening above those mountains? Several clouds are stacked up into one striking lenticular cloud. Normally, air moves much more horizontally than it does vertically. Sometimes, however, such as when wind comes off of a mountain or a hill, relatively strong vertical oscillations take place as the air stabilizes.

Панорама Марса Bonestell Panorama from Mars

If you could stand on Mars -- what could you see? One memorable vista might be the above 360-degree panoramic image taken by the robotic Spirit rover over the last year. The above image involved over 200 exposures and was released as part of Spirit's five year anniversary of landing on the red planet.

В атмосфере Марса обнаружен метан Methane Discovered in the Atmosphere of Mars

Why is there methane on Mars? No one is sure. An important confirmation that methane exists in the atmosphere of Mars occurred last week, bolstering previous controversial claims made as early as 2003.

Гиперион: спутник Сатурна со странными кратерами Saturns Hyperion: A Moon with Odd Craters

What lies at the bottom of Hyperion's strange craters? Nobody knows. To help find out, the robot Cassini spacecraft now orbiting Saturn swooped past the sponge-textured moon in late 2005 and took an image of unprecedented detail.

IC 410 и NGC 1893 IC 410 and NGC 1893

Dusty emission nebula IC 410 lies about 12,000 light-years away in the northern constellation Auriga. The cloud of glowing gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893.

МКС: отражения Земли ISS: Reflections of Earth

Remarkable details are visible in this view of the orbiting International Space Station (ISS), recorded with a small telescope on planet Earth through a clear twilight sky. Seen on December 27th at about...

Солярография с подвесным мостом Suspension Bridge Solargraph

If every picture tells a story, this one might make a novel. The six month long exposure compresses the time from December 17, 2007 to June 21, 2008 into a single point of view.

NGC 2170: небесный натюрморт NGC 2170: Celestial Still Life

Is this a painting or a photograph? In this beautiful celestial still life composed with a cosmic brush, dusty nebula NGC 2170 shines near the image center. Reflecting the light of nearby hot stars...

Самая большая Луна 2009 года над Альпами Largest Moon of 2009 Over the Alps

A larger moon will not be seen this year. This past weekend, the largest full Moon of 2009 could be seen from almost any clear location on planet Earth at night. The high angular extent of the full Moon was caused by the Moon being unusually close to Earth during its full phase.

Необычные столбы света над Латвией Unusual Light Pillars Over Latvia

What's happening over that town? Close inspection shows these strange columns of light occur over bright lights, and so likely involve falling ice crystals reflecting back these lights. The reason why these pillars...
