Up close and personal with a leaking magnetosphere

Cosmic plumbing You may or may not know that Earth's magnetosphere leaks. You might think it is therefore time to send for the intergalactic plumbers. And in a manner of speaking, that is what the European Space Agency has done, in collaboration with its counterparts in China.â¦

Spill a little wasabi at home and, well, it's messy. Spill some in the weightlessness of the international space station and you're looking at a major cleanup job. By the Associated Press.

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 breeze of interstellar helium atoms is blowing through the solar system. Thankfully, we have our shields up! The solar system's deflector shield is a giant magnetic bubble called "the heliosphere." It's part of the sun's magnetic field.

If a satellite encounters high-energy particles or other 'space weather' phenomena before ground controllers can take action, on-board electronics could be disrupted, scientific instruments damaged and, in very rare and extreme cases, spacecraft may even be lost.
