New York, The Very Large Telescope array (VLT) is the flagship facility for European ground-based astronomy at the beginning of the third Millennium. Its main 12-meter array has fifty antennas, each measuring 12 meters in diameter, which together act as a single telescope — an interferometer. They are so big they wouldn’t fit in your living room! It's designed to spot some of the most distant, ancient galaxies ever seen, and to probe the areas around young stars for planets in the process of forming.The opening of the telescope array is being celebrated in an inauguration ceremony on Wednesday (March 13) at its observation site in Chile's Atacama desert. 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. ALMA continues to carefully monitor the evolving global situation regarding the COVID-19 pandemic and will post ALMA-related updates as News Items to the Science Portal. 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. Planning and constructing the observatory took thousands of scientists and engineers from around the world more than 10 years. Watch live Monday: SpaceX to launch 1st Starlink mission of 2021, 'Old Faithful' galaxy has brilliant outbursts every 114 days. The electronic detector called the "front end" that amplifies and converts the radio signals collected at each ALMA antenna must be kept at a chilling 4 Kelvin ( minus 452 degrees Fahrenheit, or minus 269 degrees Celsius), to prevent introducing noise to the signal. It is the world's most advanced optical instrument, consisting of four Unit Telescopes with main mirrors of 8.2m diameter and four movable 1.8m diameter Auxiliary Telescopes. 42 Illuminating Telescope Facts By Karin Lehnardt, Senior Writer Published March 27, 2017 Telescopes not only help magnify far-away objects but they also allow humans to “see” parts of the light spectrum beyond visible light, including gamma rays, X-rays, ultraviolet rays, infrared rays, microwaves, and radio waves.

ALMA is a transformative radio telescope that can study cosmic light that straddles the boundary between radio and infrared. TELESCOPE. Everyone likes the stars and the Milky Way. The observatory is accurate enough to discern a golf ball 9 miles (15 kilometers) away. Then, in 1608, Hans Lipperhey in the Netherlands invented the telescope. The Italian astronomer Galileo Galilei built his own telescopes, some 400 years ago. Together, they study the birth of galaxies, stars and planets. Mirrors. Join our Space Forums to keep talking space on the latest missions, night sky and more! ALMA will look at the skies in millimeter and submillimeter wavelengths (submillimeter light has slightly shorter wavelengths than millimeter light, whose wavelengths are measured in the millimeters). ALMA is a single telescope of revolutionary design, composed initially of 66 high-precision antennas, and operating at wavelengths of 0.32 to 3.6 mm. This observatory is the result of an international association between Europe (ESO), North America (NRAO) and East Asia (NAOJ), in collaboration with the Republic of Chile.

The Atacama Cosmology Telescope (ACT) is a six-metre telescope on Cerro Toco in the Atacama Desert in the north of Chile, near the Llano de Chajnantor Observatory.It is designed to make high-resolution, microwave-wavelength surveys of the sky in order to study the cosmic microwave background radiation (CMB). Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. Telescopes also collect more light than your eyes can. Your eyes are just not good enough to study the stars in much detail. These ranges fall along the boundary between the radio and microwave bands of the electromagnetic spectrum, and have longer wavelengths than optical light. No, it’s much more. There are other existing telescopes that observe millimeter/submillimeter waves, but ALMA is an outstanding telescope with exceptionally high sensitivity and resolution capable of imaging the unknown universe that was never possible to see before. Working together, the separate ALMA telescopes become one giant telescope up to 11 miles (16 km) across.
