But solar flares — the brief, intense flashes of light caused by the sun's magnetic fields changing shape suddenly — couldn't be causing the heating because none were observed.

Trying to observe the details of Saturn's auroras has essentially been a hit - and - miss proposal, the researchers say: The times at which solar flares strike the planet aren't readily predictable, and until now the Hubble telescope hasn't been looking at Saturn at the proper wavelengths just when a solar flare arrived.

«Furthermore, the white - light flare observed by Valderrama is, chronologically, the third one recorded in the history of solar physics,» adds Vaquero.

During the last two months, several of these powerful solar flares have been observed, some with associated coronal mass ejections that, in turn, can produce geomagnetic storms that perturb the communication systems in some regions of Earth, especially radio broadcasts and GPS systems.

Scientists studying solar flares employ special satellites and instruments that do not operate with visible light, but a white - light flare can be observed with «normal» telescopes that use visible light, as Valderrama y Aguilar did in 1886.

The successful candidate will work on the analysis and interpretation of solar flare related radio - bursts observed with the VLA, in collaboration with our project partner at the New Jersey Institute of Technology, NJ, with the possibility of getting involved in STIX science and operations planning.

As well as keeping an eye out for solar flares, it will also be looking well past the Sun to gain a better grasp of the earliest, most distant galaxies we have ever observed to give astronomers a better idea of what happened in the very early days of our Universe, and perhaps shed light on how the relationship between gravity and dark matter evolved.

Here we present a joint hydrodynamic and radiative model showing that during the first seconds of beam injection the effects caused by beam electrons can reproduce Hα line profiles with large red - shifts closely matching those observed in a C1.5 flare by the Swedish Solar Telescope.
