A Year of Sunspots
This is an unusual rainbow. For one thing, the rainbow is not complete, appearing only in a sunlit fan -- but that by itself is not very unusual. What is most unusual is the fake location of the Sun. The Sun appears to be toward the front, just below those hills -- but it is not. That is not how rainbows work. Rainbows involve a backward reflection from falling rain, so that the Sun must really be behind you. In this case, gaps between clouds near the setting Sun allowed rays to cross the entire sky and appear to converge in front, an unusual phenomenon called anticrepuscular rays. The photo was taken with a phone last week at sunset in Presenzano, Italy. The seemingly reverse rainbow was noticed when hanging up laundry.
As the solar cycle breathes life into our local star, the rhythmic dance of sunspots captured in "A Year of Sunspots" serves as a visceral reminder of the volatile magnetic temperaments that govern stellar evolution. This solar restlessness finds a distant, chilling echo in the atmosphere of GJ 357 d, a world drifting 9.44 parsecs away within its star's temperate embrace. While our Sun’s magnetic outbursts shape our terrestrial weather, the stability of GJ 357 d’s potential greenhouse effect remains the critical variable in determining if its 220K surface can truly harbor the warmth required for life.
