Well‚ the world didnt end (yay)‚ so lets talk about Mondays total solar eclipse and those strange pink spots around its periphery. If you were lucky enough to snap a pic of the eclipse yourself‚ or have seen some of the incredible photos taken by others‚ you may have noticed bright pink‚ red‚ and orange coming off of the Sun like streamers. These are called solar prominences but what are they?What is a solar prominence?According to NASA‚ a solar prominence is a large‚ bright feature extending outward from the Suns surface. Formed of plasma‚ prominences are anchored in the Suns photosphere and extend into its outer atmosphere‚ or corona.Prominences can vary in size and shape. Usually‚ they are longer than the diameter of the Earth some have even extended for millions of kilometers and most often one end is tethered to the Sun‚ creating a streamer effect. But sometimes‚ they occur as an arch‚ with both ends anchored to sunspot regions.A solar prominence in 2010.Image credit: NASA Solar Dynamics ObservatoryThe glowing appendages form as plasma flows along a tangled and twisted structure of magnetic fields generated by the suns internal dynamo‚ explains NASA. When it becomes unstable‚ it erupts outward and creates the spots we see in the pictures.Also known as filaments‚ prominences form over the course of about a day and can last for several months.Their rosy color comes from electrically charged hydrogen and helium in the plasma. Prominences emit light in the red part of the spectrum as hydrogen fluoresces during the hydrogen alpha transition. However‚ when combined with white light from ordinary thermal emissions‚ it can produce a pink effect‚ as seen here:Pink solar prominences could be seen around Monday';s eclipse.Image credit: NASA HQ PHOTO via Flickr (CC BY-NC-ND 2.0)Why was this visible during the eclipse?Mondays eclipse happened very close to solar maximum when the Sun is at its most active and the chances of flares and coronal mass ejections (CMEs) are highest.Solar maximum is a product of the 22-year cycle of the Suns magnetic field‚ during which two peaks occur around 11 years apart. When the cycle reaches its peak‚ as it is now‚ the magnetic field becomes tangled‚ which means weve been treated to all sorts of phenomena of late‚ including sunspots‚ flares‚ and the CMEs that cause auroras.Even when solar activity is at a minimum‚ prominences can be seen around the edge of the Sun but during solar maximum‚ theyre even more abundant‚ which is why theyve popped up in so many eclipse photos.Solar prominences werent the only phenomena we witnessed on Monday. We also saw the rare light effect known as Bailys beads‚ which occurs when light from the Sun can be glimpsed at the Moons jagged edges‚ looking a little like beads.Baily';s beads seen just before totality on April 8.Image credit: NASA HQ PHOTO via Flickr (CC BY-NC-ND 2.0)Unfortunately‚ those in the US will have to wait until 2044 for the next total solar eclipse‚ but as the Sun heads toward its peak of activity‚ expect to see plenty more spectacles from our star in the coming months.All explainer articles are confirmed byfact checkersto be correct at time of publishing.
