Barranco de Badajoz

Valle de Güímar is a Spanish Denominación de Origen Protegida (DOP) for wines located along the south-eastern coastline of Tenerife (Canary Islands, Spain), and acquired its DO in 1996.

The Pyramids of Güímar are six rectangular pyramid-shaped, terraced structures built from lava stone without the use of mortar. They are located in the district of Chacona, part of the town of Güímar on the island of Tenerife in the Canary Islands, Spain. The structures have been dated to the 19th century AD and they may originally have been a byproduct of contemporary agricultural techniques. These pyramids stand as high as 12m. Other pyramids employing the same methods and materials of construction can be found in various sites on Tenerife. In Güímar itself there were nine pyramids, only six of which survive.

Güímar (Spanish pronunciation: [ˈgwimaɾ]) is the name of a municipality, town and valley in the eastern part of the Spanish island of Tenerife, one of the Canary Islands, and part of Santa Cruz de Tenerife (province). The municipality extends for 102.9 square kilometers from the mountainous interior to the beaches on the Atlantic, and borders the municipalities of La Orotava, Arafo and Fasnia. Its estimated population is 18,589 (2013). The TF-1 motorway passes through the municipality. The municipality is famous for its pyramids. It is also the location of the barranco de Badajoz. A portion of its volcanic landscape has been set aside as the Nature reserve of Malpaís of Güímar, its highest point being Montaña Grande.

Arafo is a municipality of the southeastern part of the island of Tenerife in the province of Santa Cruz de Tenerife, on the Canary Islands. The town Arafo is situated 5 km west of the coast town Candelaria and 22 km southwest of Santa Cruz de Tenerife. The TF-1 motorway passes through the eastern part of the municipality.

Cave-Shrine of Chinguaro is a Roman Catholic church and cave located in Güímar on Tenerife (Canary Islands, Spain). It was the traditional palace of the Guanche King of the Menceyato de Güímar, Acaimo. In this cave, the ancient Guanches worshiped the Virgin of Candelaria (Patron Saint of the Canary Islands) as the goddess Chaxiraxi of their traditional faith. This deity was worshiped in the Canary Islands until the Castillian conquest of the archipelago. The icon was later identified with the Virgin Mary and was moved by the Guanches themselves to the Cave of Achbinico in Candelaria. This cave was the first shrine devoted to the Virgin of Candelaria, and the first aboriginal Guanche shrine to contain a Christian idol in the Canary Islands. However, the Guanches at the time still generally adhered to their traditional religion. The cave is also a place of great archaeological importance.

The Bradford Robotic Telescope (BRT) is an autonomous astronomical telescope located at Teide Observatory, Tenerife in the Canary Islands. It is owned by the University of Bradford and was built between 2002 and 2004 for remote use by schools and individuals worldwide. As of November 2009, the observatory has returned over 70,000 images and has more than 23,000 users.On May 15, 2016, the BRT team announced via email to registered users that control of the Bradford Telescope would be transferred to the Open University, and renamed the Autonomous Robotic Telescope (ART). The transfer of the telescope assets to the Open University was completed in 2016. The original telescope hardware is in the process of being decommissioned (May 2017) and has been replaced by two telescopes on Mount Teide, the Physics Innovations Robotic Telescope Explorer (PIRATE) and the COmpletely Autonomous Service Telescope (COAST) installed as part of the OpenSTEM Labs facility.

Teide Observatory (Spanish: Observatorio del Teide), IAU code 954, is an astronomical observatory on Mount Teide at 2,390 metres (7,840 ft), located on Tenerife, Spain. It has been operated by the Instituto de Astrofísica de Canarias since its inauguration in 1964. It became one of the first major international observatories, attracting telescopes from different countries around the world because of the good astronomical seeing conditions. Later, the emphasis for optical telescopes shifted more towards Roque de los Muchachos Observatory on La Palma.

The Vacuum Tower Telescope is an evacuated-optics solar telescope located at the Teide Observatory on Tenerife in the Canary Islands. It is operated by the Kiepenheuer-Institut für Sonnenphysik (KIS).It was built between 1983 and 1986, with first light in 1988. It has a 70-centimetre (28-inch) diameter primary mirror and a focal length of 46 metres (151 ft). Thanks to an adaptive optics system KAOS (Kiepenheuer-institute Adaptive Optic System), in operation since spring 2000, it is able to resolve details down to 0.2 arc seconds (150 km) on the Sun's surface.

COSMOSOMAS is a circular scanning astronomical microwave experiment to investigate the Cosmic Microwave Background anisotropy and diffuse emission from the Galaxy on angular scales from 1 to 5 degrees. It was designed and built by the Instituto de Astrofísica de Canarias (IAC) in Tenerife, Spain, in 1998. Its name comes from "COSMOlogical Structures On Medium Angular Scales" referring to CMB fluctuations. This experiment grew out experience of the previous Tenerife Experiment with the need to go to smaller angular scales with greater sensitivity. The experiment consists of two instruments, COSMO15 (three channels at 12.7, 14.7 and 16.3 GHz) and COSMO11 (two hands of linear polarization at 10.9 GHz). Both instruments are based on a circular scanning sky strategy, consisting of a 60 rpm spinning flat mirror directing the sky radiation into an off-axis paraboloidal antenna, whose size is 1.8-m in the COSMO15 and 2.4-m in the COSMO11. These antennas focus the radiation on to cryogenically cooled HEMT-based receivers, both at an operating temperature of 20K (-253 C) and in the frequency range of 10–12 GHz for COSMO11, and 12–18 GHz for COSMO15. In the COSMO15 instrument, the signal is split by a set of three filters, allowing simultaneous observations at 13, 15 and 17 GHz. Thus, four 1-degree resolution sky maps complete in right ascension and covering 20 degrees in declination are obtained every day at these frequencies. The most important result to come from this experiment is the cleanest detection of "spinning dust" in the Perseus molecular cloud. These are very small dust grains which can spin thousands of million times a second. If they have an asymmetrical electrical charge they can radiate like a lot of tiny dipole antennas. This cloud is very bright at infra-red wavelengths due to thermal emission from the large dust grains, but very little emission would be expected at microwave wavelengths by this type of dust. Instead there is a broad bump of signal centered on 22 GHz, a factor of 50 above the expected level of signal.

The QUIJOTE CMB Experiment is an ongoing experiment started in November 2012, and led by Rafael Rebolo López, with the goal of characterizing the polarization of the cosmic microwave background (CMB) and other galactic and extragalactic emission in the frequency range 10 to 40 GHz, at angular scales of 1°. These measurements will complement at low frequency and correct from galactic contamination those obtained by the Planck satellite from 2009 to 2013.The two QUIJOTE telescopes are placed at the Teide Observatory, run by the Spanish Instituto de Astrofisica de Canarias (IAC). Both telescopes were produced by the IDOM company in Spain.

The Very Small Array (VSA) was a 14-element interferometric radio telescope operating between 26 and 36 GHz that is used to study the cosmic microwave background radiation. It was a collaboration between the University of Cambridge, University of Manchester and the Instituto de Astrofisica de Canarias (Tenerife), and was located at the Observatorio del Teide on Tenerife. The array was built at the Mullard Radio Astronomy Observatory by the Cavendish Astrophysics Group and Jodrell Bank Observatory, and was funded by PPARC (now STFC). The design was strongly based on the Cosmic Anisotropy Telescope.The telescope was comparable in terms of capabilities to several other CMB experiments, including the balloon-based BOOMERanG and MAXIMA, and the ground-based DASI and CBI.

GroundBIRD is an experiment to observe the cosmic microwave background at 145 and 220GHz. It aims to observe the B-mode polarisation signal from inflation in the early universe. It is located at Teide Observatory, on the island of Tenerife in the Canary Islands.
