When is heavy water (i.e., that formed with deuterium instead of simple hydrogen) formed in the universe? Very early into protoplanetary system formation, it seems!

A group led by Fujimoto-san et al have uncovered a primordial galaxy, just 930 million years after the Big Bang (z=6.072). The galaxy is composed of at least 15 dense, star-forming clumps embedded within a rotating disk like a "Cosmic Grape". These clumps, with sizes ranging from 10 to 60 […]
The first ALMA image of the HL Tauri protoplanetary disk. The image color palette orange and red, with more emission in brighter colors. Grooves can be seen in the disks where protoplanets have been eating away at the material.
Of course all of this builds on the initial success from the original ALMA long-baseline campaing that looked at HL Tau and found its protoplanetary disk in all its glory… […]

This image shows the 15 brightest protoplanetary disks (ordered in 5 columns and 3 rows) in Ophiuchus (as observed by the ODISEA project and DSHARP), in which one can observe the presence of rings and grooves of different sizes that indicate the presence of bodies in formation.

Using data from ALMA and advanced simulations, a research team led by Santiago Orcajo from the Instituto de Astrofísica de La Plata in Argentina (CONICET and Universidad Nacional de La Plata) has presented a new model that traces the evolution of […]

An international collaboration called exoALMA is using our telescopes to s peer through the dusty disks where planets are born. Thanks to their newly developed advanced imaging techniques, exoALMA has revealed the most sharp images of young solar systems, as never seen before. This research […]
Six years since ALMA crucially helped the Event Horizon Telescope take the first image of a supermassive black hole in a distant galaxy… you can relive it all below!

EHT Reveals New Insights of Jets from Supermassive Black Holes. ALMA is a big part of EHT, and in this case provided the most accurate calibration for the observations, which was used later for the longer baselines between EHT telescopes.

A picture of a celebratory cake with white frosting on a small table, with 12 ALMA-like antennas on top, together with 12 stars, and ALMA and 12 written in bold blue letters. Behind, a larger table has a round cloth with a white ALMA-like antenna printed on it, surrounded by white, light blue, and dark blue balloons with stars. That cloth is surrounded by additional things to eat, like plates of fruit, parfaits, jellies, and other delicacies.
BTW, did I mention ALMA is now officially 12 years old? On March 13th, 2013, ALMA was famously commanded by then President Sebastián Piñera to point to the galactic center!
Since then, ALMA has been delivering stunning science year after year, and during […]

This image corresponds to Figure 1 in the paper. The image is divided into multiple panels labeled (a) through (g): Panel (a) shows the now classical large-scale MeerKAT radio observation at 1.28 GHz of the galactic center, rotated to better align with other panels. The galactic center sureoundings appear as a cloudy, filamentary structures with brighter regions and darker spots. Sgr A* (our galaxy’s black hole) is labeled with a star symbol. Two red boxes highlight regions with different velocity components (50 km s⁻¹ and 20 km s⁻¹). Panels (b) and (c) are zoomed-in views of these velocity components showing SiO 5-4 transition observations from ALMA (Atacama Large Millimeter/submillimeter Array) at low resolution. These panels show filament-like structures. Panel (b) shows the 50 km s⁻¹ component, while panel, with an outline indicating where the ALMA observation was made. Panel (c) shows the 20 km s⁻¹ component with three regions labeled A, B, and C indicating additional ALMA observations. Panel (d) corresponds to the ALMA observation outlined in panel (b). Panels (e) to (g) corresponds to regions A to C in panel (c). Those panels show many filaments with coherent speeds, sometimes perpendicular to other flows.
ALMA Discovers “Space Tornadoes” Around the Milky Way’s Core!
Although the galaxy’s central molecular zone (CMZ) has long been known to be filled with swirling dust and gas molecules cycling through formation and destruction, the mechanism that drives this […]

The text reads: ALMA Observatory is looking for a new Science Archive Content Manager (SACM) Internal & external ALMA JAO opportunity The successful candidate will be part of the Data Management Group (DMG) within the Joint ALMA Observatory (JAO). She/he will join a very active team of astronomers (Science Archive Content Managers - SACMs). Some of the major responsibilities will be related to: - QA of the science data products produced by the pipeline. - Manual data reduction, depending on level of expertise and first level of investigation on issues (hardware or software). - Contribution to defining specifications and testing of new pipeline heuristics, as well as define, update or improve procedures. Minimum requirements: - Master's degree in astronomy with minimum three years of relevant working experience. PHD degree will be an asset. - Experience in data processing of astronomical data. Good command of Unix/Linux. - Experience in sub-mm/radio interferometric and/or single-dish data reduction, and Python programming skills will be an asset - Fluent in English is a must. Fluent in Spanish is an asset.
We're hiring again! Now we're looking for an Science Archive Content Manager (aka SACM). This person will be a mamber of the Data Management Group, and will be integral on creating useful science data from the raw data generated by the observatory. And in […]

A blue Atacama sky with three ALMA antennas in the forefront, and a few more behind. The Milky Way is shown on the top part. The white ALMA logo is stamped on the top left, and Happy New Year! is written in a cursive font, somewhat imitating chalk on slate.
Happy new year from ALMA!
