One twelvemonth ago on August 21 , 2017 , gazillion of Americans were treated to astunning total solar eclipseacross the country . But a group of scientists were awaiting a monumental present moment of their own .

During a total solar eclipse , the Sun ’s corona – its outer atmosphere – becomes visible around the Moon in a rare event . Normally , the corona is particularly heavy to examine owe to the light of the Sun .

So in the build up to the American eclipse , a team from Predictive Science Inc. ground in San Diego published a survey foreshadow what the solar corona would look like . They educate a model that model what the corona should reckon like , and eagerly expect their results .

“ Waiting for sum , you know exactly what you ’ve promise and what you ’re await , ” Predictive Science researcher Zoran Miki ? said in a statement . “ Because you work with the mannequin so much and see the prediction so many times , it ’s burned into your brain . There ’s a lot of anxiousness because if you ’re totally wrong , it ’s a moment embarrassing . ”

But it was mostly good news for the scientist . Publishing their findings inNature Astronomy , the team say their prevision was very interchangeable to the actual Saint Ulmo’s fire they observed . They were able to predict how the Sun ’s whirl magnetized bailiwick would move the visible corona .

To make the manikin work , they fed computers and supercomputers datum on the Sun ’s magnetised field for the preceding 27 day before the occultation , which is the time it consume the Sun to make an full rotation . This let them get a good handle on how solar prominences , large and bright current of flatulency , would look . They also used figure of speech from NASA ’s Solar Dynamics Observatory ( SDO ) .

“ The model allows us to translate the kinship of observed lineament , including pennon , coronal trap , bulge , polar plumes and thin rays , to the magnetic field , ” the squad wrote in their paper .

However , their model did lack some of the finer structures learn in the Saint Ulmo’s fire , such as a squirt streaming out from the Sun ’s upper - right called a pseudostreamer . This was belike due to a magnetized field changing in that region in a way that was n’t presage .

While the science itself is interesting , it is also important . outcome like this could help us more accurately predict distance weather , as the Sun throws particles and solar wind in our management . This can affect satellites and even planes flying through the air , so getting better at foretell it is incredibly useful .
