The Earth isn’t the only planet in our Solar System that is feeling the effects of the sun’s heat. In a recent study, researchers have discovered that Mercury also has a black disk that is able to sharpen the sun’s rays. This disk, made up of a layer of dark material on the surface of the planet, is believed to be the reason for the intense heat experienced on Mercury’s dayside. This black disk is thought to be the result of an accumulation of dust particles from comets and other celestial bodies. Scientists are now hoping to use this new understanding of Mercury’s surface to gain further insight into its past and future. Stay tuned for more developments in this fascinating research!
