Detailed images on the Sun from Spacecraft

These stunning images of the Sun's restless frothing surface reveal how its magnetic field is more turbulent and dynamic than previously thought.

These stunning images of the Sun's restless frothing surface reveal how itsmagnetic field is more turbulent and dynamic than previously thought.

The structure of the Sun's magnetic field can be seen rising vertically froma sunspot in images taken by the Hinode spacecraft, which was launched lastSeptember to understand the misbehaviour of our local star and how it candisrupt communications and power grids on Earth and threaten astronauts on theway to or working on the moon.

The Hinode satellite, a joint Japanese, British and American mission, willstudy the sun's magnetic field and how its explosive energy propagates throughthe different layers of the solar atmosphere.

Solar scientists believe that Hinode, which is Japanese for Sunrise, will have as dramatic an impact onour understanding of the Sun as the Hubble Space Telescope has had on our viewof the universe.

By studying the sun's magnetic field, scientists hope to shed new light onexplosive solar activity.

In particular they want to learn if they can identify the magnetic fieldconfigurations that lead to these violent energy releases and use thisinformation to predict when these hazardous events may occur.

Where astronomers expected to see a calm region, Hinode revealed a boilingcauldron of swaying spikes.

"These structures are 8000 kilometres (5000 miles) long and some extendtwice that high," says Alan Title from Lockheed Martin in Palo Alto, California.

"For the first time, we are now able to make out tiny granules of hot gasthat rise and fall in the sun's magnetized atmosphere," adds Dick Fisher,director of NASA's Heliophysics Division, Washington.

"These images will open a new era of study on some of the sun's processesthat effect Earth, astronauts, orbiting satellites and the solar system."
