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 do you know about ALMA?
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.

What is an array in astronomy?
An array is a group of several radio antennas observing together creating — in effect — a single telescope many miles across.
What is ALMA project?
The Atacama Large Millimeter/submillimeter Array (ALMA) is a giant radio telescope which was constructed in Chile in cooperation with the Republic of Chile, through global partnership of East Asia (including Japan), North America, and the member states of the European Organisation for Astronomical Research in the …
How much did ALMA cost?
$1.3 billion 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.
What type of telescope is ALMA?
radio telescope 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.
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).
Who owns ALMA?
Alex Roberts Alex Roberts, chef/owner of Restaurant Alma. Restaurant Alma served its first dinner on Nov. 4, 1999. It's a significant date in Minnesota culinary history, because in the intervening years, Alma (the name is the Spanish word for “soul”) has grown into one of the region's top-rated restaurants.
What is the VLA in New Mexico?
Very Large Array (VLA), radio telescope system situated on the plains of San Agustin near Socorro, New Mexico, U.S. The VLA went into operation in 1980 and is the most powerful radio telescope in the world. It is operated by the National Radio Astronomy Observatory.
