The Indian Space Research Organisation (ISRO) has announced
that a payload onboard the Chandrayaan-2 Orbiter, the Large Area Soft X-ray
Spectrometer (CLASS), has discovered solar proton events that dramatically
increase the radiation exposure to humans in space.
The equipment also observed coronal mass ejections (CMEs) on
January 18, a tremendous torrent of ionised material and magnetic fields that
reach Earth a few days later, causing geomagnetic storms and lighting up the
polar sky with auroras, according to the ISRO on Wednesday.
"Such multi-point observations aid in our understanding
of propagation and its impact on many planetary systems," the paper added.
When the sun is active, it produces stunning eruptions known
as solar flares, which occasionally shoot highly energetic particles (known as
solar proton events or SPEs) into interplanetary space.
