The arches look like they're glowing as they give off ultraviolet light, which is actually invisible to the human eye — but researchers colorized it to make the details of the magnetic arches really pop.
Scientists are keeping an eye on the sun to learn more about the star and watch for any potentially dangerous space weather that could harmfully impact Earth. A huge burst of plasma in our planet's magnetic field could create problems with power grids on Earth, satellites in space and even humans on orbit, but monitoring the sun can give researchers a heads up about any extreme space weather heading toward us.

Solar flares (the sun)
NASA video of swirling magnetic arches on the sun is completely mesmerizing
The sun emitted a significant solar flare, peaking at 7:28 p.m. EST on Dec. 19, 2014. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. (Photo via NASA/SDO)
On Feb. 24, 2014, the sun emitted a significant solar flare, peaking at 7:49 p.m. EST. NASA's Solar Dynamics Observatory (SDO), which keeps a constant watch on the sun, captured images of the event. These SDO images from 7:25 p.m. EST on Feb. 24 show the first moments of this X-class flare in different wavelengths of light -- seen as the bright spot that appears on the left limb of the sun. Hot solar material can be seen hovering above the active region in the sun's atmosphere, the corona.
Solar flares are powerful bursts of radiation, appearing as giant flashes of light in the SDO images. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

This Monday, Jan. 12, 2015 photo provided by NASA shows the first notable solar flare of the year, as observed from NASA's Solar Dynamics Observatory. The sun emitted a mid-level solar flare, peaking at 11:24 p.m. EST on Monday. NASAâs Solar Dynamics Observatory (SDO) is a NASA mission which has been observing the sun since 2010. (AP Photo/NASA)
The bright flash of an X1.6-class flare can be seen on the right side of the sun in this image captured by NASA's Solar Dynamics Observatory. This image shows extreme ultraviolet light of 131 Angstroms, which highlights the intensely hot material of a flare and which is typically colorized in teal. (Photo via NASA/SDO)
On Oct. 25, 2014, the sun emitted its fifth substantial flare since Oct.19. This flare was classified as an X1-class flare and it peaked at 1:08 p.m. EDT, as seen as a bright flash of light in this image from NASA's SDO. The image shows extreme ultraviolet light in the 131-angstrom wavelength, which highlights the intensely hot material in a flare and which is typically colorized in teal. (Photo via NASA/SDO)
NASA's Solar Dynamics Observatory captured this image of an X2.0-class solar flare bursting off the lower right side of the sun on Oct. 27, 2014. The image shows a blend of extreme ultraviolet light with wavelengths of 131 and 171 Angstroms. (Photo via NASA/SDO)
The bright flash of an M-class flare is seen exploding on the left side of the sun in this image from Nov. 5, 2014. The image was captured by NASA's Solar Dynamics Observatory in extreme ultraviolet light that was colorized in red and gold. (Photo via NASA/SDO)
On Jan. 27, 2012, a large X-class flare erupted from an active region near the solar west limb. X-class flares are the most powerful of all solar events. Seen here is an image of the flare captured by the X-ray telescope on Hinode. This image shows an emission from plasma heated to greater than eight million degrees during the energy release process of the flare. (Photo via JAXA/Hinode)
