Period 114 Phase 2: Deadline

Published: 03 Jul 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 114 is Tuesday, 6 August 2024. The Service Mode guidelines provide detailed information about Phase 2 material preparation with the web application p2, while the instrument overview table provides quick links to user manuals, tools and p2 tutorials for individual instruments.

Thomas Klein, Director of the La Silla Paranal Observatory as of 1 August 2024

Published: 27 Jun 2024

As previously announced, an open process to recruit an LPO Director was launched by ESO in late 2023. Thomas Klein, currently Deputy Director of the La Silla Paranal Observatory and Programme Manager of the Integrated Operations Programme, was selected following a competitive process. Thomas will begin his service as LPO Director on 1 August 2024, reporting to Andreas Kaufer, who will remain ESO Director of Operations.  

ESO Sets up Merged Instrumentation Programme

Published: 24 Jun 2024

Following discussions with Council and the Scientific and Technical Committee during 2023, ESO is now merging the three instrumentation programmes that are in place for its optical/infrared telescopes: The Paranal Instrumentation Programme; the ELT instrumentation project, for the ELT construction instruments; and the Armazones Instrumentation Programme, for the future ELT instrumentation.

VLT BlueMUSE Phase A Kicked-off

Published: 24 Jun 2024

BlueMUSE is an optical seeing-limited, blue-optimised, medium spectral resolution, panoramic integral-field-spectrograph, to be installed at the VLT. With a wide wavelength coverage (350 - 580 nm), an average spectral resolution of R=4000 and a field-of-view of 1arcmin², BlueMUSE will offer new and unique science opportunities in many fields of astrophysics. ESO has approved the Phase A  (conceptual design) of the project led by PI Johan Richard from the Centre de Recherche Astrophysique de Lyon (France), the laboratory leading the consortium composed of a total of 9 institutes world-wide. The expected first-light for the BlueMUSE instrument is 2031.

"Cosmic Ecosystems in Radio & Optical", ESO-SKA 2024 conference, Busselton, Australia, 9-13 December 2024

Published: 17 Jun 2024

Gas flowing into, out of, and around galaxies plays a key role in shaping how their properties evolve over cosmic time. The mechanisms driving these behaviors are poorly understood, largely because we lack detailed knowledge of fundamental gas properties across multiple scales and phases. Tackling these issues necessarily requires a multi-wavelength approach. Fortunately, the southern hemisphere hosts the most comprehensive suite of observational facilities available for tackling this topic, in the form of the ESO, ALMA, the Square Kilometer Array (SKA) precursors (MWA, ASKAP and MeerKAT), and very soon, the SKA-Mid and SKA-Low telescopes. This conference, which will take place near Busselton Australia, from 9 to 13 December 2024, is sponsored by both ESO and the SKA as it supports the joint science of both facilities that will be dominant in astronomy in the coming decade.

The ESO Science Newsletter

The April 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.
