The scientists saw a spark in the Sun with the camera

Scientists have at their disposal the best quality and accurate as of today forms the solar atmosphere. For shooting used an experimental camera mounted on the rocket.

Scientists have at their disposal the best quality and accurate as of today forms the solar atmosphere. For shooting used an experimental camera mounted on the rocket.

System managed to shoot only for five minutes, but it was enough to discover a previously unknown phenomenon, which the researchers called "sparks".

This bright points appear along the magnetic field lines, which are a huge amount of energy.

The spots appear and disappear randomly after about 25 seconds. Across the Sun, they are microscopic, though equal in size in the UK.

Perhaps this discovery will help to explain why the external temperature of the solar atmosphere, called the corona, a much higher surface temperature of the light, that is the photosphere.

"The temperature in the solar corona is millions of degrees higher, and dozens of years, we could not find an explanation. Sparks, which we call the extreme ultraviolet points, it seems, are evidence of a very localized and frequent outbursts of energy, which can then accumulate and easy to heat the solar corona , "- he said in an interview with BBC BBC.

Video of this phenomenon has been collected in a series of photographs and posted on YouTube.

To capture a new generation of tool was used, which was tested by means of geophysical rocket. Researchers had hoped to test his concept, design and performance, to continue to use the device for space missions.

During the test, the camera was turned to the active regions of the Sun's center.

In addition to the scientists saw sparks huge accumulations of charged gas (plasma), moving at great speed along paths created by magnetic fields.

Scientists continue to study the Sun with the device after it is displayed on a satellite in space.
