ALMA stands for Atacama Large Millimeter/submillimeter Array and is one of the worlds largest and most famous radio observatories.
The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of 66 radio telescopes in the Atacama Desert of northern Chile, which observe electromagnetic radiation at millimeter and submillimeter wavelengths. The array has been constructed on the 5,000 m (16,000 ft) elevation Chajnantor plateau – near the Llano de Chajnantor Observatory and the Atacama Pathfinder Experiment.
This location was chosen for its high elevation and low humidity, factors which are crucial to reduce noise and decrease signal attenuation due to Earth’s atmosphere. ALMA is expected to provide insight on star birth during the early Stelliferous era and detailed imaging of local star and planet formation. – Wikipedia
When visiting I decided to make a panorama of one of the dishes using my Canon EOS 5D MKII and a 24mm lens.
The result is panorama with a resolution of 29998×9403 or 282,071,194 pixels which translates to 282 Megapixels with an aspect ratio of 3.19.
Try zooming in on it!
