Saturns Hexagon and Rings
20.02.2013

Why would clouds form a hexagon on Saturn? Nobody is sure. Originally discovered during the Voyager flybys of Saturn in the 1980s, nobody has ever seen anything like it anywhere else in the Solar System.

Annapurna Star Trails

In myth, Atlas holds up the heavens. But in this moonlit mountainscape, peaks of the Himalayan Annapurna Range appear to prop up the sky as seen from Ghandruk, Nepal. From left to right the three main peaks are Annapurna South (7,219 meters), Hiunchuli (6,441 metes), and Machapuchare (6,995 meters).

The Little Dipper

At 2nd magnitude, Polaris is far from the brightest star in the night sky. But it is the brightest star at the left of this well-composed, starry mosaic spanning about 23 degrees across the northern sky asterism dubbed the Little Dipper.

The Northern Milky Way

Many of the stars in our home Milky Way Galaxy appear together as a dim band on the sky that passes nearly over the Earth's north and south poles. Pictured above is the part of our Galaxy that passes closest over the north pole.

North Celestial Tree

An ancient tree seems to reach out and touch Earth's North Celestial Pole in this well-planned night skyscape. Consecutive exposures for the timelapse composition were recorded with a camera fixed to a tripod in the Yiwu Desert Poplar Forests in northwest Xinjiang, China.

Unusual Aurora During Solar Wind Dropout

On May 10, for some unknown reason, the Solar Wind virtually stopped. Normally our Sun emits a wind of between five and ten energetic particles per cubic centimeter moving outward at about 500 kilometers per second.

Saturns Hexagon Comes to Light
22.01.2012

Believe it or not, this is the North Pole of Saturn. It is unclear how an unusual hexagonal cloud system that surrounds Saturn's north pole was created, keeps its shape, or how long it will last.

Saturn Hurricane

North Celestial Tree
23.10.2013

If you climbed this magnificent tree, it looks like you could reach out and touch the North Celestial Pole at the center of all the star trail arcs. The well-composed image was recorded over a period of nearly 2 hours as a series of 30 second long, consecutive exposures on the night of October 5.
