phenomenon Aurora Borealis that looked like a curtain of flickering light in the sky the North Pole of planet Earth turns occur also on other planets.
As is the case with on planet Earth, light phenomena on other planets are also associated with sun exposure.
Quoted by the Daily Mail, researchers from University College London (UCL) for the first time witnessed the aurora at Jupiter. The difference, because the amount of energy in the process, the aurora is comprised of X-rays instead of light that can be visible to the eye.
The study itself using data collected by the Chandra X-Ray Observatory NASA. The researchers revealed that solar storms to trigger auroral X-rays are 8 times brighter than usual.
"Aurora there are hundreds of times more energetic and far greater than that on Earth," said William Dunn, the head writer and PhD student at the Mullard Space Science Laboratory, UCL.
"The surface of the Earth may be sufficient if placed in the aurora of Jupiter. The composition of the planet's atmospheric chemistry broadly controlled by the sun, while Jupiter is so bright aurora and aurora digdaya so even that is controlling the chemical composition of Jupiter's atmosphere, far beyond the sun. "
"So, if the surface Juipter look to the sky, the aurora will be visible in the sky that stretches as far as the eye can see and much brighter than the sun, even in daylight."
"If our eyes could see X-rays, the visible aurora was pulsing, ie bright and dim every 45 minutes. If it was storming sun, pulse every 26 minutes. In the aurora was also quite warm because it exposed a lot of infra red radiation. "

Dunn continued, "There is a power struggle between exposure to the solar wind and the magnetosphere of Jupiter. We want to understand these interactions and their impact on the planet. "
"By studying how the aurora change, we can discover more about the area of space controlled by the magnetic field of Jupiter and whether it is influenced by the sun."
"Understanding the relationship that is important to so many magnetic objects throughout the solar system, including in exoplanets, planets dwarf and neutron stars."
Sun continuously throw bursts of particles into space by the solar wind. When there is a giant storm burst, the wind became stronger and compress the magnetosphere of Jupiter thus shifting the boundary layer of the magnetosphere with the solar wind. Shifting the boundaries around 2 million km in space.
This study found that the interaction at the border triggered
high-energy X-rays in the "Northern Sky" Jupiter and covers a wider area than the surface of the Earth.
The impact of solar storms on Jupiter's aurora traced through monitoring the X-rays emitted in two observations that each lasts for 11 hours in October 2011. At that time, massive bursts of corona (coronal mass ejection, CME) between the planets was calculated to have reached the planet.
Interplanetary CME is a massive burst of gas and magnetic fields arising from the sun's corona and initiated into the solar wind.
Dunn added, "In 2000, one of the most surprising findings is the 'hot spots' on the brilliant X-ray auroras rotate together with the planet."
"The hotspots that mendenyutkan bursts of X-rays every 45 minutes, almost as a beacon light for the planet. When a solar storm arrived in 2011, we saw the hot spot it beat faster, are more luminous every 26 minutes. "
"We're not sure about what causes additional speed increases while there is a storm, we suspect this pulsation associated with the solar wind and also new bright aurora that."
Scientists use the data set to create a globe images to determine the source of X-ray activity and characterize the area that later can be investigated at any other time.
These findings melengkap by NASA's Juno mission will arrive at Jupiter in the summer. The mission aims to understand the relationship between the two largest structure in the solar system, which is the region of space controlled by the magnetic field of Jupiter and the territory controlled by the solar wind.
As part of that mission, Juno will investigate Jupiter relationship with the sun and the solar wind by studying the magnetic field, the magnetosphere, and the planet's aurora.

UCL team hope to discover how the X-rays transformed by collecting compliance data using XMM-Newton-which is an X-ray observations belonging to the European Space Agency (ESA) -and the Chandra X-ray NASA.
Dunn said to MailOnline, "We only ever see the daylight side of the Jupiter aurora, because that is visible from the planet Earth."
"That is, we do not know what happened on the night side. Juno will provide the first opportunity to see the aurora in the night side of Jupiter. What-we are both still guessed. This is actually a bit strange, because we are accustomed to seeing in Earth's northern lights at night. "
"By comparing the findings from Jupiter with what we already know on Earth will help explain how space weather are driven by the solar wind interacts with the Earth's magnetosphere," said professor Graziella Branduardi-Raymont, who also came from the Mullard Space Science Laboratory at UCL.
"A new understanding of how Jupiter affected by the Sun's atmosphere will help us characterize the atmosphere of exoplanets that give clues as to whether a planet the possibility of supporting life as we have known."
Another study led by Tomoki Kimura of Japan's space agency (Japan Aerospace Exploration Agency, JAXA) has just published on Tuesday, in collaboration with researchers UCL.
The study reported that the auroral X-rays turned out to respond to 'blowing' the solar wind is a little quieter. This deepens the relationship between Jupiter and the solar wind.
