"The collision of solar wind with a planet's magnetic field can produce a region of space with extra hot, extra dense charged gas called the magnetopause, as well as an area of low pressure just behind it, analogous to how one might stand behind a windbreaker during an intense gale," said Lee Suttle, a scientist at Imperial College London. Most recently, researchers at the MAGPIE laboratory have been able to reproduce some of the important features of this collision in the laboratory.

A different laboratory study uses high-power lasers to study stellar winds produced by the universe's most energetic objects, such as active galactic nuclei and pulsars. By focusing a laser onto a small area of a metal, electrons are heated to energies so high that they move at speeds close to the speed of light (Figure 2).
