Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun’s gravity, and their technique promises a major contribution to a frontier area of basic physics.
ALMA Telescope Makes Successful Antenna Link
The Atacama Large Millimeter/submillimeter Array, an immense international telescope project under construction in northern Chile, reached a major milestone on April 30, when two ALMA antennas were linked together as an integrated system to observe an astronomical object for the first time.
First North American ALMA Antenna
Astronomers celebrated today the formal acceptance of the first North American antenna by the Joint ALMA Observatory. ALMA, the Atacama Large Millimeter/submillimeter Array, is a gathering armada of short-wavelength radio telescopes whose combined power will enable astronomers to probe with unprecedented sharpness phenomena and regions that are beyond the reach of visible-light telescopes.
ALMA Observatory Equipped with its First Antenna
High in the Atacama region of northern Chile one of the world’s most advanced telescopes has just passed a…
Welcome Taiwan as ALMA Partner
The National Radio Astronomy Observatory has announced a formal agreement enabling Taiwanese astronomers to participate in the North American component of the international ALMA partnership, alongside American and Canadian astronomers. Taiwan’s efforts will be led by the Academia Sinica Institute of Astronomy and Astrophysics.
Telescope’s High-Tech ‘Heart’
The Expanded Very Large Array, part of the National Radio Astronomy Observatory, took a giant step toward completion on August 7 with successful testing of advanced digital hardware designed to combine signals from its upgraded radio-telescope antennas to produce high resolution images of celestial objects.
