Solar flares are intense bursts of radiation emitted by the sun during solar storms, standing as the most powerful explosions in the solar system. According to NASA, the biggest flares can have as much energy<\/a> as a billion hydrogen bombs, and yet astronomers have only recently obtained record-breaking photographs of the phenomenon.<\/p>\n

On August 8, 2024, the Daniel K. Inouye Solar Telescope at Maui\u2019s National Solar Observatory<\/a> (NSO) captured the most detailed shots ever of a solar flare. The imagery featured \u201cdark coronal loop strands\u201d with \u201cunprecedented clarity,\u201d per a statement<\/a>, marking a potential breakthrough in resolving the \u201cfundamental scale of solar coronal loops.\u201d These \u201cloops,\u201d or arches of plasma, follow the sun\u2019s magnetic field lines, often portending the solar flares that release a sudden rush of energy. Even from millions of miles away, such blasts can significantly impact infrastructure on Earth, whether it be our power grids or communications systems.<\/p>\n

\u201cThis is the first time the Inouye Solar Telescope has ever observed an X-class flare,\u201d Cole Tamburri, a solar physicist at the University of Colorado Boulder, says. \u201cThese flares are among the most energetic events our star produces, and we were fortunate to catch this one under perfect observing conditions.\u201d<\/p>\n

Before now, scientists couldn\u2019t fully determine the size of these plasma loops, and could only speculate that they could measure anywhere from 10 to 100 kilometers (about 6 to 62 miles) in width. Confirming those theories has been virtually impossible, due to resolution limitations in older telescopes. The new data gathered by the Inouye Solar Telescope, however, offers a high-definition glimpse into the loops\u2014both big and small\u2014for the first time. On average, loops measured about 30 miles across, but some were as small as 13 miles, which also happens to be right at the telescope\u2019s resolution limit.<\/p>\n

\u201cBefore Inouye, we could only imagine what this scale looked like,\u201d Tamburri explained. \u201cNow we can see it directly. These are the smallest coronal loops ever imaged on the sun.\u201d<\/p>\n

When tuned to the H-alpha filter, Inouye\u2019s Visible Broadband Imager (VBI) instrument can resolve features down to about 15 miles\u2014more than 2.5 times sharper than the next-best solar telescope, per NSO.<\/p>\n

\u201cWe\u2019re finally peering into the spatial scales we\u2019ve been speculating about for years,\u201d Tamburri adds. \u201cThis opens the door to studying not just their size, but their shapes, their evolution, and even the scales where magnetic reconnection\u2014the engine behind flares\u2014occurs.\u201d<\/p>\n

One fruitful discovery is that these loops might be \u201celementary structures,\u201d rather than simply \u201cbundles.\u201d<\/p>\n

\u201cIf that\u2019s the case, we\u2019re not just resolving bundles of loops; we\u2019re resolving individual loops for the first time,\u201d Tamburri says. \u201cIt\u2019s like going from seeing a forest to suddenly seeing every single tree.\u201d<\/p>\n

Scientists hope that this new imaging can lead to improvements in solar flare modeling and a better understanding of the magnetic field in the sun\u2019s corona. But even the most casual viewer will find much to enjoy in these photos: deep-red ribbons arch and swirl across a fiery plain, with bright flares peppered throughout. Such detail would never have been possible to achieve without the Inouye Solar Telescope, NSO claims.<\/p>\n

\u201cIt\u2019s a landmark moment in solar science,\u201d Tamburri concludes. \u201cWe\u2019re finally seeing the sun at the scales it works on.\u201d\n<\/p>\n
