What does the ALMA telescope do?

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 does ALMA stand for telescope?

Atacama Large Millimeter and Submillimeter Array
Atacama Large Millimeter Array

What did the ALMA telescope discover?

ALMA (the Atacama Large Millimeter/submillimeter Array) is the most complex observatory ever built. With the unique ability to see and create detailed imagery of the parts of space that are difficult to see, ALMA can see star and planet formation, black holes, and the first galaxies of the universe.

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 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.

When was the ALMA array built?

ALMA began observations in 2011 with 16 12-metre dishes and was completed in 2013. Its frequency coverage ranges between 84 and 720 gigahertz (or wavelengths between 0.42 and 3.6 mm).

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.

Is ALMA a boy or girl name?

Alma as a girl’s name is pronounced AL-mah. It is of Latin, Italian, Hebrew and Arabic origin, and the meaning of Alma is “nourishing, kind; soul; young woman; learned”.

What kind of telescope is ALMA?

single telescope
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 was imaged by ALMA?

This new ALMA image shows the outcome of a stellar fight: a complex and stunning gas environment surrounding the binary HD101584. The colours represent speed, going from blue — gas moving the fastest towards us — to red — gas moving the fastest away from us.
