Who / What
The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer consisting of 66 radio telescopes located in the Atacama Desert of northern Chile. It observes electromagnetic radiation at millimeter and submillimeter wavelengths to study the universe. This entity is not a person but rather an astronomical observatory.
Background & History
ALMA was constructed on the 5,000 m (16,000 ft) elevation Chajnantor plateau in the Atacama Desert, near the Llano de Chajnantor Observatory and the Atacama Pathfinder Experiment. The location was strategically chosen for its high elevation and low humidity to minimize atmospheric interference. Construction involved international collaboration and aimed to provide unprecedented sensitivity and resolution in millimeter and submillimeter astronomy.
Why Notable
ALMA is notable for its ability to observe the universe at millimeter and submillimeter wavelengths, providing insights into star and planet formation, and the evolution of galaxies. Its high elevation and low humidity location are crucial for minimizing atmospheric noise. The array has significantly advanced astronomical research by offering unprecedented detail in observations.
In the News
ALMA continues to be a vital tool for astronomers, with ongoing observations contributing to discoveries about the early universe and the formation of planetary systems. Recent developments include upgrades to the array's capabilities and new scientific findings based on its data. Its data is continually being analyzed and yielding new insights into cosmic phenomena.
