Tonight, you could watch the Perseid meteor shower show depending on where you are. During peak hours, you can see about 100 meteors per hour.
The rain of Perseids are not stars, but debris, remains of the Swift-Tuttle kite which is the largest object in our solar system that passes very close to the Earth in a cyclic manner.
He Swift-Tuttle kite (formally called 109P / Swift-Tuttle) was independently discovered by Lewis Swift on July 16, 1862 and by Horace Parnell Tuttle on July 19, 1862. According to an article in New Scientist, the comet's orbit could lead to impact with Earth or the Moon, although the impact would possibly not take place over the next two millennia. According to NASA, the comet measures 26 km in diameter (the asteroid that supposedly killed the dinosaurs only measured 10 km).
Thanks to him (and before he kills us all), the night of August 11 to 13 takes place one of the astronomical phenomena of the year. It will reach its peak of activity at dawn on Tuesday 13, but not in all points of Spain will be equally visible. One of the reasons is the cloudiness, but also that there will be an almost full moon.
The most problematic places to see the show will be Soria, Cantabria and Girona, as well as the Canary Islands, Murcia and La Rioja. The clouds will be scarcer in the provinces of the Valencian Community, Teruel, Cuenca, Albacete, Almería, Navarra, Burgos and Coruña. In the rest of Spain the sky will be totally clear. A good place to see the rain of stars in Madrid can be the Parque del Oeste or the Casa de Campo area, remote areas of the city. In Catalonia a good option would be the Astronomical Park of Montsec
You don't need binoculars or telescopes to see the Perseids, they are visible to the naked eye. That said, it is worth having a star observation team to take a closer look at the cosmic light show.
