Using solar wind, and other forms of passive energy, our future water networks will be operate with far more efficiency and convenience than anything imaginable today.

An unexpected pattern has been glimpsed in the solar wind the turbulent plasma of charged particles that streams from the sun. It offers clues for handling plasmas that roil inside nuclear fusion reactors On earth.

and electrons the solar wind streams from the sun and pervades the solar system. Its flow is turbulent containing eddies and moving at different speeds in different directions.

Now Sandra Chapman of the University of Warwick UK and her colleagues have examined the solar wind's behaviour using NASA's twin STEREO spacecraft.

One flies just within Earth's orbit around the sun the other just outside it allowing the pair to obtain unique measurements of solar wind behaviour.

Enter the solar wind. Though less dense and cooler than the hydrogen of a fusion reactor the wind is a plasma

The great thing about solar wind turbulence is that the satellites sit right inside so it can be observed in exquisite detail says Steve Cowley of the Culham Centre for Fusion energy UK.

and take whatever the solar wind gives it it can actually fight back. Earth is surrounded always by a bubble of magnetism called the magnetosphere

which protects us from the bulk of the solar wind a stream of high-energy particles constantly flowing from the sun

But we also know that the sun pumps out a constant stream of charged particles called the solar wind

Earth is protected from the solar wind by a relatively strong global magnetic field which repels charged particles from the sun explains Nick Schneider of the Laboratory for Atmospheric

and Space Physics in Boulder Colorado who has worked on Sprint-A. Still the solar wind would have been much stronger

Because Venus is closer to the sun the solar wind might have stripped gaseous water from its early atmosphere leaving a thick haze of mostly carbon dioxide that turned the planet's surface into a hellish desert.

It is thought the solar wind thinned the Red planet's atmosphere over time making it cold and dry.

Sprint-A will help from afar by looking for the extreme UV radiation generated as the solar wind slams into the upper atmospheres of both Mars

By observing this phenomenon we will investigate how the solar wind affects the upper atmosphere of planets and how the planetary atmosphere escapes into outer space.

At the same time a stream of particles blowing out from the sun the solar wind inflates a bubble of plasma around the solar system called the heliosphere Astronomers have assumed long that the sun's motion through the galaxy squashes

when charged particles from the solar wind collide with other charged particles in the outer heliosphere Some of these neutral atoms are bounced back towards us.

Around solar minimum you get slow solar wind around low to mid-latitudes from the sun

Most of the moon's exosphere comes from the solar wind, which is a thin stream of electrically conducting gas blown from the surface of the sun into space at around a million miles per hour.

Most of the solar wind is hydrogen and helium but it contains many other elements in small quantities,

While most of the lunar exosphere comes from the solar wind, the readings showed that some gas comes from lunar rocks.

and upticks in renewable electricity generation there using solar wind and hydropower could have contributed to the reversal.

which causes the Earth auroral displays the planet magnetic field interacting with the solar wind. hat we see on this object appears to be the same phenomenon wee seen on Jupiter, for example,

During magnetic storms which are driven solar wind the electrons accelerate to high speeds and enter the atmosphere in the polar regions.

The idea for a spacecraft to be equipped with a solar sail to use the solar wind for propulsion was described by the late astrophysicist Carl Sagan four decades ago. ecause it has a constant acceleration,

It keeps out harmful solar winds, which would strip away our atmosphere and surface water and bombard us with radiation if left unchecked.

but it collapsed after around four billion years and left the planet vulnerable to atmospheric stripping by solar wind o
