Tenerife: a “window” to the universe

Did you know that Tenerife is one of the best destinations for astrotourism in Spain? This island is a priviliged place to observe the night sky. Do you want to know what phenomena you can observe this 2021? Then, do not miss this post!

Since 1988, the Canary Islands have had a Law on the Protection of Astronomical Quality at the Observatories of the main astrophysics institute, called “Instituto de Astrofísica de Canarias” (IAC). This is known as the Canary Islands Sky Law, whose purpose is to ensure the researches in this field of study and protect the quality of the canarian observatories. 

This law has encouraged the creation of the Starlight Foundation, a non-profit organization for “the dissemination of astronomy and the coordination, management and promotion of the principles and philosophy of the Starlight movement”, as it is said on their  official website. You can also read on this website that one of the main purposes is “to promote scientific tourism and, more specifically, star tourism”. To achieve this, they have developed the certification system “Starlight Tourist Destinations” to give a special consideration to specific places that are protected against the light pollution and have the ideal sky quality and infrastructure to do this activity. 

At the present, may 2021, the list of Starlight Tourist Destinations is composed of 36 places places from around the world and, among them, six belong to the Canary Islands and, more specifically, three are located in Tenerife and are the following: 

  • La Matanza de Acentejo

  • El Teide

  • Granadilla de Abona

Other key points are the two main observatories in the islands: the first one in Roque de Los Muchachos in La Palma and the second one in Izaña, in Tenerife. These sites have the largest collection of optical and infrared facilities for astrophysics in the European Union.

  • Teide Observatory, due to its geographical location and the transparency and quality of its sky, is reserved for the study of the sun, using the best European solar telescopes. It was in 1979, right in this observatory, that the heliosesmology was born, a technique with which scientists study the vibrations of our star and get an insight of its interior. 

  • Roque de los Muchachos Observatory has the largest optical and infrared telescope in the world, GRANTECAN, as well as twenty telescopes from various countries and European scientific institutions.

The pleasant temperatures of the coast change when you ascend to Teide National Park (being at more tan 2,000 meters above sea level). At night, temperatures drop and you should protect you against the cold with warm clothes from head to toe. A beanie, gloves, warm socks and a closed shoe with a thick sole are recommended, as well as carrying a blanket with which you can stay in the ground and a hot drink. 

What celestial bodies can be observed?


In this magical experience you will have the opportunity to identify several celestial objects such as constellations, planets, nebulas, galaxies, double stars, open clusters, artificial satellites, shooting stars and the Moon. You might bring your own telescope, astronomical binoculars or your camera to make the event even more delightful.
 
In addition, Tenerife is located at 28º north latitude. This fact is what makes possible we are able to see a higher number of constellations than other places in Europe throughout the year.
