ALMA Doubles its Power in New Phase of More Advanced Observations

Green light for ALMA Early Science Cycle 1
8 January 2013

ALMA (the Atacama Large Millimeter/submillimeter Array) has begun a new and more advanced phase of science observations. This phase is known as Early Science Cycle 1, and will last until October 2013. The telescope’s power has been greatly increased: it will make observations with more antennas, spread over a greater distance, than ever before, and will use antennas from the Atacama Compact Array (ACA) for the first time.

Although ALMA is still under construction, its first scientific operations began in 2011. This phase was known as Early Science Cycle 0. ALMA has already outperformed all other telescopes of its kind, and the unprecedented capabilities of the telescope have brought a first wave of exciting scientific results over the last year (see for example ann12101, eso1216, eso1239, and eso1248).
