Astronomers using a giant telescope atop a volcano have discovered a hot spot at the tip of Saturn's south pole. The infrared images captured by the Keck I telescope at the W.M. Keck Observatory atop Mauna Kea on the Big Island suggest a warm polar vortex &#151; a large-scale weather pattern likened to a jet stream on Earth that occurs in the upper atmosphere. It's the first such hot vortex ever discovered in the solar system.

A discovery now has some astronomers entertaining visions of icy volcanoes roiling on some of the tiny worlds circling beyond Neptune, at least at one time.

By Joe Bauman Deseret Morning News  Utahns who missed Sunday's rare planetary grouping -- and that's most of the state because of cloud cover -- will get another chance at a space spectacular early Thursday morning.

You&#39;re speeding through space at 28 000 kilometres per hour, at times the outside temperature gets down to a chilling minus two hundred degrees Celsius, there is no quick getaway.

The Cassini spacecraft&#39;s close flyby of Saturn&#39;s mysterious moon Titan this week revealed clouds that will give clues to its weather, but the pass left scientists still puzzled about its surface.

Hawaii&#39;s Keck Observatory has confirmed the existence of a Jupiter-sized planet orbiting a distant star, the first one spotted by a network of astronomers using telescopes no larger than the ones you can buy in stores.

Scientists analysing data captured by the Cassini-Huygens spacecraft as it swept past Saturn&#39;s moon Titan, have described a cold landscape carved by winds and perhaps puddled with organic lakes.

The first "sniffs of air" of two huge far-away planets reveal that they seem to be missing water, a surprising finding amid weather unlike any planets in our solar system with blast furnace-like gusts amid supersonic winds.

In late afternoon, the wispy clouds part. For the first time I discern the distant domes, tiny and white, on the peak of blue-grey Mauna Kea, but a heavy cloud hovers above. Dr. Hammel tells me that once the sun sets, this cloud will cool, sink and wrap the telescopes in its fog, unless &#150; there&#39;s a small possibility &#150; the cloud sinks all the way beneath the summit, down below the telescopes. Despite the bleak predictions in all the weather forecasts for tonight, I begin to hope that we&#39;ll finally get some data.
