NASA just released the closest pictures ever taken of the Sun not to be confused with the highest resolution ones courtesy of the Solar Orbiter, a collaboration between NASA and the European Space Agency (ESA). The close-ups are breathtaking to look at, and also reveal something entirely unexpected as well: small flares theyre calling campfires, all over the stars surface.

The campfires we are talking about here are the little nephews of solar flares, at least a million, perhaps a billion times smaller, said principal investigator David Berghmans, an astrophysicist at the Royal Observatory of Belgium in Brussels, in a a NASA statement. When looking at the new high resolution EUI images, they are literally everywhere we look.

Despite the majority of staff at ground control at the European Space Operations Center in Germany having to work from home during the ongoing pandemic, the team was able to obtain the images from the Solar Orbiter as it made its closest pass on June 15.

The Orbiter came within just 48 million miles of the Sun. Its closest pass within the next year or so will get it within just 26.1 million miles. NASAs Parker Solar Probe came even closer in June, getting to within just 11.6 million miles from the surface.

A closer flyby also means better images. Because the camera itself doesnt doesnt have any zoom capability, that zooming happens by getting closer to the Sun, Daniel Mller, ESAs Solar Orbiter Project Scientist, told The Verge.

These unprecedented pictures of the Sun are the closest we have ever obtained, Holly Gilbert, NASA project scientist for the mission at NASAs Goddard Space Flight Center, said inthe NASA statement. These amazing images will help scientists piece together the Suns atmospheric layers, which is important for understanding how it drives space weather near the Earth and throughout the solar system.

Scientists are still unsure as to the exact nature of these little flare-ups each of them are about the size of a country.

But we might soon know more thanks to the Solar Orbiters other scientific instruments. The Spectral Imaging of the Coronal Environment, or SPICE instrument, can measure the exact temperature of each nanoflare.

So were eagerly awaiting our next data set, Frdric Auchre, principal investigator for SPICE operations at the Institute for Space Astrophysics in Orsay, France, said in NASAs statement. The hope is to detect nanoflares for sure and to quantify their role in coronal heating.

Mller suggested to The Verge that the campfires in total they could add up enough energy to heat the corona. In other words, all these tiny flares could add up to enough energy to heat up the Suns entire atmosphere.

The Solar Orbiter is outfitted with an entire suite of scientific gear. Counting the cameras and the SPICE instrument, the small spacecraft features ten different instruments, all collecting invaluable data about our star.

Scientists werent expecting to find anything groundbreaking from the Orbiters first ever images yet thanks to the Extreme Ultraviolet Imager, astronomers were astonished to discover what they called campfires all over the Suns surface.

We didnt really expect such great results right from the start, Mller, ESAs Solar Orbiter Project Scientist, said in an ESA statement. We can also see how our ten scientific instruments complement each other, providing a holistic picture of the Sun and the surrounding environment.

As part of a different experiment, scientists are excited to soon get a much closer and detailed look at structures of solar wind, massive streams of charged particles released from the Suns corona that make their way through the solar system.

Thanks to yet another instrument, the researchers are also getting an unprecedented look at the Suns magnetic field, particularly at each of its poles.
