Today I am going to present you a visual challenge in El Reto de los Lectores de La Vanguardia, which is actually three. It is about finding in the photographs, captured from the house site in Altet (Urgell), the polar star, the shooting stars and the contrails of the airplanes.
Let's go by parts. First you have to locate in this first image the polar star, which indicates the north and is the only star that is practically always at the same point in the sky.
Next, I propose this other game: you have to locate in this other image the trail of three planes. They are aircraft because you can see the lights that flash, which are brighter points and there is not one that rotates.
Finally, can you see the two fireballs or shooting stars that appear in this other snapshot?
How many of the three visual challenges have you been able to solve? One? Two? All three!... None?... In any case, here is the solution in each of the three photographs.
