How big is the Atacama Large Millimeter Array?
12 metres Atacama Large Millimeter Array (ALMA), radio telescope system located on the Chajnantor plateau in Chile's Atacama Desert at an altitude of 5,000 metres (16,500 feet). ALMA consists of 66 parabolic dishes, 54 of which are 12 metres (39 feet) in diameter and 12 of which are 7 metres (23 feet) in diameter.
When was the Atacama Large Millimeter Array built?
The array has been constructed on the 5,000 m (16,000 ft) elevation Chajnantor plateau - near the Llano de Chajnantor Observatory and the Atacama Pathfinder Experiment....Project timeline.
| Date | Activity |
|---|---|
| 1995 | ESO/NRAO/NAOJ joint site testing with Chile. |
| May 1998 | Start of phase 1 (design & development). |
Which telescope observatory is in a Chilean desert and actually consists of 4 large telescopes right near one another?
Seated in the Atacama Desert of Chile, the European Southern Observatory (ESO)'s Very Large Telescope (VLT) consists of four main telescopes and four smaller telescopes that can be used separately or combined into a single larger instrument powerful enough to distinguish two car headlights at the distance of the moon.
Where is the ALMA one of the most powerful telescopes in the world located in Chile?
Telescopes for this kind of astronomy must be built on high, dry sites, such as the 5000-m high plateau at Chajnantor, one of the highest astronomical observatory sites on Earth. The ALMA site, some 50 km east of San Pedro de Atacama in northern Chile, is in one of the driest places on Earth.
Where is the Atacama telescope?
Chile The Atacama Cosmology Telescope (ACT) is a six-meter diameter telescope located on Cerro Toco in the Atacama Desert in the north of Chile, near the Llano de Chajnantor Observatory.
How much did ALMA cost?
The ALMA observatory cost $1.3 billion to construct, with the price tag being split by the three sponsoring regions: North America, Europe and East Asia. Of the total cost, about $500 million was contributed by U.S. taxpayers.
Is ALMA a radio telescope?
ALMA Basics ALMA is a transformative radio telescope that can study cosmic light that straddles the boundary between radio and infrared. Most objects in the Universe emit this kind of energy, so the ability to detect it has been a driver for astronomers for decades.
What is the Very Large Telescope Array?
The Very Large Telescope array (VLT) is the flagship facility for European ground-based astronomy at the beginning of the third Millennium. It is the world's most advanced optical telescope, consisting of four Unit Telescopes with main mirrors of 8.2m diameter and four movable 1.8m diameter Auxiliary Telescopes.
How does ALMA work?
The 66 antennas at ALMA work together as though they were a single giant telescope. They use a technique known as interferometry, where two or more antennas pick up a signal from the Universe and join forces to analyze the signal and obtain information on its source of emission (whether it is a star, planet or galaxy).
How big is the ALMA telescope?
12 metres ALMA is a single telescope of revolutionary design, composed initially of 66 high-precision antennas, and operating at wavelengths of 0.32 to 3.6 mm. Its main 12-metre array has fifty antennas, each measuring 12 metres in diameter, which together act as a single telescope — an interferometer.
