Within the framework of the scientific conference “ALMA 10 years: Past, Present, Future,” which is bringing together 180 astronomers and astronomers from around the world in Puerto Varas, southern Chile, between December 4 and 8, 2023, astronomers Sergio Martín and Juan Cortés gave a press conference to show the achievements and discoveries of the Atacama Large Millimeter/submillimeter Array (ALMA) in the last decade, which have marked a milestone in our understanding of the Universe.
Over three decades ago, North America, Europe, and Japan began outlining the idea of building a millimeter observatory as three separate projects. Thanks to the leaders’ vision of that time, a joint project much more ambitious than what was initially projected was possible. A global collaboration from the Atacama plateau in Chile has been in search of our cosmic origins for a decade.
Some exciting discoveries of these first ten years of ALMA have been the first image of a black hole (with the EHT Collaboration) and impressive views of protoplanetary disks. In total, more than 3,500 scientific publications have been published thanks to this unique instrument of its kind.
As a host country, Chile has gained numerous benefits, including developing high-tech skills and promoting astronomy. Chilean scientists are guaranteed access to 10% of ALMA’s observing time, promoting significant growth in the number of local astronomers, from 50 in the early 2000s to more than 300 today.To commemorate this first decade of operations, ALMA called 180 members of its scientific community around the world to meet at a conference in which, starting today, it is sharing its latest results and in which they will be able to look at the technical challenges of the future to stay in the world’s technological vanguard.The conference that takes place in Puerto Varas between December 4 and 8 includes talks and posters from experts from around the world on cosmology and galaxies in the distant Universe, star formation, astrochemistry, exoplanets, and the Sun, to name just a few.
More News From Atacama Large Millimeter/submillimeter Array
The Atacama Large Millimeter/submillimeter Array (ALMA) has just received a “heart transplant,” high in the Atacama Desert in Northern Chile. ALMA, the most complex astronomical observatory ever built on Earth, installed a new hydrogen maser. Funded by the National Radio Astronomy Observatory (NRAO), this upgrade marks an essential investment, setting a new standard in reliability for observations.
The Event Horizon Telescope (EHT) Collaboration has released new images of supermassive black hole M87*. A recent paper published in the journal Astronomy & Astrophysics presents new images from data collected by the Atacama Large Millimeter/submillimeter Array (ALMA) and several other instruments within the EHT. These new images show a bright ring surrounding a deep central depression, “the shadow of the black hole,” as predicted by general relativity. Excitingly, the brightness peak of the ring has shifted by about 30º compared to the first images, which is consistent with scientists’ theoretical understanding of variability from turbulent material around black holes.
An international team of astronomers have found ring and spiral structures in very young planetary disks, demonstrating that planet formation may begin much earlier than once thought. The results were presented today at the 243rd Meeting of the American Astronomical Society.
An international team of astronomers has revealed mysterious star formation at the far edge of the galaxy M83. This research was presented today in a press conference at the 243rd meeting of the American Astronomical Society (AAS) in New Orleans, Louisiana. The research used several instruments operated by the National Science Foundation’s National Radio Astronomy Observatory (NRAO), including the Atacama Large Millimeter/submillimeter Array (ALMA), the Karl G. Jansky Very Large Array (VLA), and the Green Bank Telescope (GBT), along with the National Astronomical Observatory of Japan’s (NAOJ) Subaru Telescope and the NASA Galaxy Evolution Explorer (GALEX).

ALMA observes highest resolution dust polarization image ever taken of HL Tauri’s protoplanetary disk, the deepest polarization image of any disk captured thus far.
An international team of astronomers has collaborated to improve the capabilities of the Atacama Large Millimeter/submillimeter Array (ALMA), one of the world’s most powerful telescopes. Scientists from the National Science Foundation’s National Radio Astronomy Observatory (NRAO), the Joint ALMA Observatory, the National Astronomical Observatory of Japan (NAOJ), and European Southern Observatory have achieved the highest resolution observation since ALMA began operations, in one of the most challenging array configurations. The results are published today in the Astrophysical Journal.
The Event Horizon Telescope (EHT) collaboration has published new results that describe for the first time how light from the edge of the supermassive black hole M87* spirals as it escapes the black hole’s intense gravity, a signature known as circular polarization.
