ESO Science Announcements

First Release of Spectra from the ENTROPY Project - Young Planets Observed with UVES

Published: 08 Jan 2025

The ExoplaNeT accRetion mOnitoring sPectroscopic surveY (ENTROPY) aims at investigating into the until now poorly understood process of accretion among planetary mass companions. The detection of emission lines from accreting gas giants facilitates detailed investigations into this process. The data released via this collection are the high-resolution (R ∼ 50000), stacked, flux-calibrated 1D spectra obtained with the Echelle spectrograph UVES (3200–6800 Å) of the few known young, planetary-mass objects with observed emission.

Release of the VIRAC Version2 Catalogues from the VVV and VVVX Surveys

Published: 23 Dec 2024

ESO is pleased to announce the public release of the VVV Infrared Astrometric Catalogues (VIRAC) Version 2. The catalogues are based on data from the VISTA Variables in the Via Lactea (VVV) Survey and its extension, VVVX, and offer unprecedented precision in astrometric and depth.

Message from the Director General

Published: 19 Dec 2024

Dear colleagues,

From several viewpoints, 2024 was a year when ESO started to move towards new future avenues, while running very strong on its current commitments.

La Silla Paranal Period 115 Phase 2: Deadline

Published: 19 Dec 2024

With the release of the La Silla Paranal telescope schedule, the Phase 2 preparation for runs scheduled in Service Mode begins. The deadline for the submission of the Phase 2 material for Period 115 is Thursday, 6 February 2025. The Service Mode guidelines provide detailed information about Phase 2 material preparation using the web application p2, while the instrument overview table provides quick links to user manuals, tools and p2 tutorials for individual instruments.

Registration and Abstract Submission are Open - Galactic Ecosystems under the Microscope: Lessons from Highly-Resolved Studies

Published: 18 Dec 2024

Registration and abstract submision are now open for the ESO conference "Galactic Ecosystems under the Microscope: Lessons from Highly-Resoved Studies", Garching bei München, Germany, 7th to 11th July 2025. This workshop is dedicated to exploring the latest developments in resolved galaxy properties and evolution. With next-generation observatories like JWST, ELT, and the SKA, upgrades to ALMA and VLA, we are entering a new era in understanding these critical aspects of galaxies throughout cosmic history.

The ESO Science Newsletter

The December 2024 issue is now available.

The ESO Science Newsletter, mailed approximately once per month, presents the most recent announcements. Subscription is controlled through the Manage Profile link on the User Portal. Back issues (2013-) are archived.


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.
