The U.S. National Science
Foundation (NSF), in collaboration with its Canada and Taiwan partners, Japan,
Europe and Chile, inaugurated the Atacama Large Millimeter/submillimeter Array
(ALMA) today, one of the world's most powerful telescopes, as part of an
international ceremony in Chile.
Chilean President Sebastián
Piñera, members of the Chilean cabinet, U.S. NSF Director Subra Suresh, European
Southern Observatory Director General Tim de Zeeuw, Senior Vice Minister in
Japan's Ministry of Education, Culture, Sports, Science and Technology Teru
Fukui, and senior officials and scientists of partner countries participated in
the inauguration.
ALMA comprises 66 antennas
that will provide high resolution images of the earliest galaxies in the
distant universe, as well as the formation processes of planets circling stars
in our own Milky Way galaxy. Scientists from around the world will have the opportunity
to explore such objects as they never could before, with an array of telescopes
more than 100 times more capable than any previous millimeter arrays.
"NSF is excited to play a
major role in ALMA and to foster new opportunities for international collaboration
and discoveries at the cutting edge of astronomy," said Suresh. "ALMA
promises to enable transformational research into the origins and evolution of
the universe."
NSF supported the construction
of ALMA with $499 million over 11 years and funded 25 of the 66 antennas. The
agency's annual contributions to the operations of ALMA total $34 million.
"We are proud of the U.S
contribution to ALMA and the international partnership that has made ALMA
possible," said U.S. Ambassador to Chile Alejandro D. Wolff.
"U.S.-Chile collaboration in astronomy dates back to 1849. The data and
science gathered from ALMA will build on other U.S. investments in Chile,
including the Cerro Tololo Inter-American Observatory, Las Campanas Observatory
and Gemini Observatory."
ALMA is located at an altitude
of 16,500 feet in the desert of Atacama, Chile. It sits above 40 percent of the
Earth's atmosphere and virtually all of the world's water vapor. ALMA is
designed to peer into a slice of the electromagnetic spectrum at millimeter
wavelengths--light that is closer to a radio wave than to the optical light
that is seen by the human eye.
Together with NASA's future
James Webb Space Telescope, ALMA will reveal extraordinary details of the
origins of structures in our universe, extending from planets around nearby
stars to the earliest galaxies as they formed more than 12 billion years ago.
The National Radio Astronomy
Observatory (NRAO), an NSF facility, has led the North American technical and
scientific contributions to ALMA. Managed by Associated Universities, Inc.
since its inception more than 50 years ago, NRAO has remained at the frontier
of radio astronomy research through the conception, development and operation
of transformational facilities such as ALMA.
