Notice

A minor IT Maintenance and Release Window will take place between Saturday, 16 November 2024 at 08:00 CET/04:00 CLST and Sunday, 17 November 2024 at 24:00 CET/20:00 CLST.

From 08:00 CET/04:00 CLST on Saturday all ESO IT services including ERP, Email, Database Management Systems, the Scientific Archive and Internet connectivity on all ESO sites, could be subject to intermittent outages due to configuration changes in the computer rooms.

Full services won't be guaranteed before Monday 18 December 2024.  We apologize for any inconvenience caused by this.

These pages are aimed at ESO community astronomers and contain all the information required in order to prepare, execute, process and exploit observations with ESO facilities. They also provide information on the scientific activities taking place at ESO. Details can be accessed via the navigation menu.


ESO Science Announcements

The Latest Edition of ESO's Science and Technology Journal, The Messenger, is now Available Online.

Published: 15 Nov 2024

This issue 193 focuses on the potential synergies between ESO and SKAO facilities and what science would be possible with well-planned coordinated surveys. The specific cases of exploring with such surveys the Galaxy, galaxy formation and evolution, cosmology, and the epoch of reionisaiton are presented in a series of articles. Further in this issue the VST-SMASH survey and its first results are presented, as well as the latest news on the ongoing upgrades of GRAVITY+. 

Expanding Horizons: Transforming Astronomy in the 2040s

Published: 14 Nov 2024

With the Extremely Large Telescope (ESO’s ELT) just a few years away from completion, ESO has started the process to identify its next programme. The process has been given the name Expanding Horizons and will aim to identify the next transformational facility that will advance humanity’s understanding of the Universe whilst fostering international collaboration. 

Nine Letters of Intent for the KMOS Public Surveys Submitted

Published: 06 Nov 2024

By the deadline on October 15, 2024, ESO received nine letters of intent for the ESO public survey with KMOS. These letters of intent cover a wide range of scientific topics from young stellar objects to the evolution of galaxies at cosmic noon and beyond. There are three submitted letters of intent covering galactic and stellar evolution topics, followed by the local universe (two letters of intent) and galaxy evolution at higher redshift (four letters of intent). Nine PIs and more than one hundred co-Is are participating in these scientific projects. The overall total time request is equivalent to an over-subscription by a factor 5.

ESO Workshop "Galactic Ecosystems under the Microscope: Lessons from Highly-Resolved Studies", ESO Garching, 7-11 July 2025

Published: 06 Nov 2024

This is the initial announcement for the upcoming ESO workshop "Galactic Ecosystems under the Microscope: Lessons from High-Resolution Studies" at ESO Garching, 7-11 July 2025. This workshop will explore the latest developments in resolved galaxy properties and evolution. With next-generation observatories such as JWST, ELT and SKA, and upgrades to ALMA and VLA, a new era is being entered in understanding these critical aspects of galaxies throughout cosmic history.

ESO Period 115 Proposal Submission Statistics

Published: 31 Oct 2024

The deadline for proposal submission for Period 115 (1 April 2025 - 30 September 2025) was 26 September 2024. 763 valid proposals were submitted. On the VLT, the most demanded ESO instrument was MUSE with a request of 233 nights, followed by ESPRESSO with 214 nights, and XSHOOTER with 182 nights. HARPS/NIRPS on the ESO 3.6-metre telescope was the most demanded instrument at La Silla, with a combined request of 202 nights. The figure above shows the time request since Period 62, for Paranal (VLT/I), La Silla, and APEX. The fluctuations since Period 106 are partly because Large Programmes are offered only in even periods since P106. The highest peak in P106 is due to the extension of the proposal submission deadline during the pandemic.

Citing ESO data in research papers

Researchers are kindly asked to indicate the identifiers (programme IDs or Data DOIs) of the (new or archival) observations they used in their papers as explained in ESO’s data citation policy. This enables the telbib curators to cross-link research output to make data Findabie, Accessible, Interoperable, and Reusable as suggested by the FAIR Principles.  


Pitch Your Research to ESO COMM

Are you an author on an upcoming scientific study based on ESO data that could be relevant to journalists or the wider public? Or are you a Principal Investigator on ESO observations with potential to become stunning images? If so, please consider sending to ESO your paper and/or a preview of the image(s) obtained with ESO telescopes.
