On November 27, a new edition of All-Hands was held, where the ALMA community reviewed the scientific, operational, and organizational milestones of recent months with a view to 2026.

“It is essential to recognize the observatory’s achievements, especially because they are the reason why ALMA works so well and why we continue to be at the forefront of astronomy and exploration of the universe today, and that is thanks to everyone who works here”, said our Director Sean Dougherty.

During the meeting, the main scientific results of the year were reviewed, including the observation of the interstellar comet 3I/Atlas, the pioneering monitoring of stellar activity in Proxima and Alpha Centauri, and the advances made thanks to the ALMA–JWST collaboration. These efforts continue to offer new clues about the early formation of galaxies and reaffirm ALMA’s role as a key platform for global astronomy.

Another highlight was the outstanding performance of Cycle 11, which exceeded 4,300 hours of observation for the first time and delivered more than 90% of the data in less than 28 days. “This achievement, especially significant in a year marked by technical and environmental challenges, reflects the commitment, coordination, and resilience of all the teams involved, and we should be proud of that”, said Sergio Martín, Head of Science Operations.

The meeting also addressed budget and governance updates: thanks to responsible management, the overspending forecast for 2025 was reduced to less than 0.5%, while the 2026 operating budget has already been approved.

In parallel, the Wideband Sensitivity Upgrade (WSU) continues to progress, with milestones such as the first WMAC meeting, the construction of the new correlator room, the development of the fiber optic system, and the preparation of the improved computing and communications architecture.

In addition, updates were shared on infrastructure and well-being, including improvements to the HVAC system in Santiago, briefings on the OSF transportation policy, and the rollout of the new cybersecurity awareness course. The meeting also included time to recognize promotions, welcome new colleagues, and highlight recent community outreach activities.

The November All-Hands meeting closed with a shared conviction: this year’s great results are the fruit of joint efforts, and 2026 is projected as an opportunity to continue strengthening our science, our operations, and the community that makes ALMA possible.
