NASA ’s Fermi Telescope calculate at the high - energy universe , and once in a while catches the Sun irrupt up during solar storms . Some of the recent expelling from the Sun surprised scientists . Fermi should n’t have been able to see them as the solar storm were happening on the far side of the Sun .
In a newspaper publisher , published in theAstrophysical Journal , the team discuss the lawsuit of these curious outcome , have it away as behind - the - limb flair . A solar storm is associated with the sudden emission of huge swarm of shoot particles , speed to almost the speed of Inner Light by powerful magnetic fields .
Some of these particle escape into space , but others come after the charismatic field of the Sun , and the latter finally slam back into the Sun ’s surface . In doing so , they secrete a lot of da Gamma - rays .

" Fermi is seeing gamma electron beam from the side of the Sun we ’re confront , but the emission is produced by streams of molecule blasted out of solar flash on the far side of the Sun , " order author Nicola Omodei , a researcher at Stanford University , in astatement . " These atom must travel some 300,000 miles within about five minutes of the bam to produce this luminance . "
The connection between the Vasco da Gamma - electron beam discharge and the solar flare was possible thanks to NASA ’s Solar Terrestrial Relations Observatory ( STEREO ) spacecraft , which was observing the far side of the Sun during the three keep issue that occurred in 2013 and 2014 .
" observation by Fermi ’s LAT continue to have a significant impact on the solar physics community in their own right , but the add-on of STEREO observations provide extremely valuable information of how they mesh with the self-aggrandizing picture of solar activeness , " added co - source Melissa Pesce - Rollins , a research worker at the National Institute of Nuclear Physics in Pisa .
The Sun is quite dim in gamma - beam , but being so skinny , its emission can become quite powerful when it becomes more participating . The most powerful emission Fermi ever detected from our star topology happened in 2012 , when the Sun give off gamma - rays for the record - break off time of 20 hours .
