The Roque de Los Muchachos Astrophysical Observatory on La Palma island is a prestigious research centre with one of the most advanced professional telescope arrays in the world. Here is a video with spectacular images of the night sky over La Palma and of the sky at the Observatorio de La Palma at night (see note below*). In the video you can see the William Herschel Telescope, the Gran Telescopio de Canarias and other smaller telescopes.

The Roque de Los Muchachos Astrophysical Observatory offers daytime visits to its facilities (Reservations: here) but night time visits are possible during working hours.

However, do not dispair as La Palma is a Dark Sky Reserve (an Starlight Reserve) and stargazing is possible on the whole island. Here is a list and map of the astronomy viewpoints and astronomical sites of interest if you wish to stargaze. But if you need a little bit more: explanations, use of telescopes and a guided tour of the sky, you may consider joining one of our astronomy tours.

The seventh edition of the AstroMaster La Palma has ended this sunday 2nd June and once again has been a success. This international workshop has put once again La Palma on the spot for astronomy due to its international scope. A total a 14 participants from countries such as Japan, USA, UK, Italy, Mexico and Argentina,  have learned from the most reknown astrophotographer in the world: Babak Tafreshi (The World at Night,TWAN and a National Geographic photographer).

Local Press

Here we show you the first processed image produced at the workshop…and many more to come. The image credit is for Alex Martin from USA. We also add all the articles on local newspapers about the AstroMaster La Palma, 2019 edition.  Images from previous editions has been published in International Astronomy Magazines such as “Astronomy” or the National Geographic.

“Without any doubts, the astromaster is a relevant for the level of expertise, but also promotionally of the island of La Palma. We are now known, not just for the astronomy at the Observatory at the Roque de Los Muchachos but for the astrotourismo and fantastic nightscape photography”, said Ana García.

Next edition

The astromaster workshop for 2020 will be announced early June 2019. For inscription and info please see here: astromaster2020.

The TNG is equipped with 3 instruments permanently installed in its foci and offers a variety of observing modes covering the optical and near-infrared spectrum, offering wide-field imaging up to high-resolution spectroscopy.

Its most relevant instrument is the HARPS-N “High Precision Radial Speed ​​Planter in the Northern Hemisphere. It is one of the most accurate spectrographs in the world that has the main objective of discovering and characterizing extrasolar planets the size of the Earth (Echelle spectrometer at 383-633 nm wavelengths and with spectral resolution of R = 115000). In practice HARPS-N measures the slight oscillation of the star caused by the presence of the planet (in m/s) with which it can estimate the mass of the exoplanets, their chemical composition and distance to the star.

History

The agreements for the construction of the telescope in La Palma were signed in 1979 and the telescope The telescope saw its “first light” in 1998. Until June 2004, the telescope was operated by the Galileo Galilei Genter, created in 1997 by the Consorzio Nazionale per l’Astronomia e l’Astrofisica (CNAA). From  July 27, 2004, the new Galileo Galilei Foundation, funded by the National Institute of Astrophysics (INAF), is responsible for the management of the TNG.

Results

The TNG is currently looking mainly for exoplanets, a very relevant field in astrophysics at the moment. The first exoplanet discovered by the TNG was the Kepler 78 b, a planet similar to Earth in size and mass but much hotter, surface temperature can reach 5,000 degrees. Another exoplanet also in the news, and found by the TNG (published May 2017), belongs to the star GJ625 (Gliese 625), a red dwarf close to the Sun, is in the area of ​​habitability, which means that could host lifetime. The Kepler 78b and the planet of GJ625 are some of the more than 1,000 already discovered exoplanets (Earth-like planets).

Curiosities

In February 2013, an international team, led by Spanish astrophysicists, characterized the 2012 asteroid DA14 using the Gran Telescopio Canarias (GTC) and the Galileo Nazionale Telescope at the Roque de los Muchachos Observatory in La Palma. They were able to measure the maximum approach to Earth.

In the TNG, all the rooms are kept at a certain temperature, which varies depending on the room. The telescope should be half a degree below the minimum outside temperature recorded the previous night to minimize the airflow around the telescope and avoid turbulence that greatly reduces the image quality caused by the temperature gradient when opening the telescope.

The second building, dome of the telescope is a structure of an approximate height of 26 m. And occupies an area of ​​about 400 m2. The building is entirely made of metal structure, with a fixed first floor, while the other 3 can rotate around the vertical axis of the building, in solidarity, in synchrony with the rotation of the telescope.

History

       
The UK’s Science and Engineering Research Council (SERC) began planning the telescope in 1974 with a final budget of 10 million pounds. In 1981, 20% of the SERC negotiated a 20% stake with Holland, so the telescope belongs to the United Kingdom and the rest to the Netherlands. The first light of the telescope was on June 1, 1981 using the instrument TAURUS-2.

Results
       
The most outstanding results extracted with data obtained in this telescope are:
       
* The discovery of the first evidence of a supermassive black hole (Sgr A*) in the center of the Milky Way.
   
* The first optical observation of a gamma ray burst

Curiosities

       
* The telescope takes the name of the astronomer William Herschel (Germany 1738 – England 1822), a musician without scientific formation who began his interest in the astronomy to the 35 years of age. This astronomer discovered the planet Uranus with a 1.2m reflecting telescope that built the same along with his sister since he could not afford to buy a refractor telescope of similar size to the use at the time. Herschel was also a pioneer in the design of the azimuth mount that is now used in telescopes like the WHT. In 1981, with the first light of the telescope, was the bicentennial of the discovery of Uranus, hence the telescope bears the name of William Herschel.

* The WHT is like a Swiss Army Knife. In each focus an instrument is placed and in turn has several instruments interchangeable with each other with relative ease. Currently professional astronomers can request observation time for the following instruments:

• • ISIS – espectrograph
  • LIRIS – infrarred espectrograph
  • ACAM – ccd camera and low resolution spectroscopy
  • AF2/WYFFOS – multiobject espectroscopy
  • NAOMI/OASIS – espectroscopy
  • Adaptative optics
  • NAOMI/INGRID – infrarred imaging

History

After years in the drawing boards of the Institute of Astrophysics of the Canary Islands, in 1994 GRANTECAN SA when it was founded, with the aim of designing and building the world’s largest telescope: the Gran Telescopio Canarias. Subsequently, agreements were signed with the Government of Mexico, for two of their universities to participate in the project and also joined as a partner the United States, through the University of Florida. The telescope cost no less than 130 million euros and has an annual budget of nearly 9 million Euros.

The construction of the telescope at the Observatorio del Roque de Los Muchachos on the island of La Palma, began in 2000 and the start of the science phase began operating in March 2009. The telescope time is shared by Spanish scientists (90%), Mexico (5%) and the U.S. (5%), the same percentage who contributed to the initial project.

Curiosities

• We can compare the power of sight of the telescope to four million human eyes. It could distinguish the headlights of a car at about 20,000 miles away.
• The metal structure of the dome is assembled with screws 16,000 and 43,000 metal nuts.
• The mirrors are cleaned with powdered snow made of carbon dioxide. There are 6 spare mirrors.
• GTC employs about 65 people or so (about 45 on the island of La Palma alone). There are 4 working groups: maintenance, science, management and development.
• Any day between 10-20 people are working on the telescope, the rest work in offices remotely. However, at night, despite its size, the telescope requires only 2 people to run observations: an astronomer and a technician. It’s all computerized.

Results

The Gran Telescopio de Canarias studies the nature of black holes, star and galaxy formation of a very young Universe. A fairly booming field developed here is the study of distant exoplanets (Planetary Transits) and very energetic events such as: very distant supernovae & black hole collisions.
