The second Fast Track Channel (FTC) call for Period 117 will be released on Wednesday, 18 November 2026. This FTC 117B call will cover the last two months of Period 117 (1 March 2027 - 30 April 2027). The proposal submission deadline is scheduled for Wednesday, 16 December 2026. More information on the available time per telescope, as well as the requirements and restrictions for submitting a proposal via this channel, will be provided via the Fast Track Channel webpage once the call is released.

This first release of CORALIE data contains the spectra of the historical radial-velocity planet-search programme carried out by the Geneva Observatory exoplanet team with the CORALIE spectrograph on the Euler 1.2m telescope at La Silla. CORALIE covers 390 to 690 nm at a resolving power of R ≈ 60000. Fibre A is placed on the target, while fibre B records a simultaneous ThAr (before June 2015) or Fabry-Perot reference, or the sky. Instrument upgrades in 2007 and 2014 introduced radial-velocity zero-point offsets, so the release contains spectra from three instrument versions (CORALIE98, CORALIE07 and CORALIE14) and stops at the 2024 intervention.

The goal of the observing programme 0113.C-2186(A), PI A. Stavros, is to better understand the Low-Ionization Structures (LISs) commonly found in Planetary nebulae (PNe). This project uses X-shooter to obtain the first UV-to-NIR spectra from a sample of 12 LISs with different shapes and types in 9 PNe with a variety of morphologies, ages and stellar parameters.

This data release provides FLAMES/UVES spectra observed as part of the ESO program 112.25ES.001 (P.I. P. Kervella) with the main scientific goal of estimating interstellar extinction of 16 Galactic Cepheid variable stars. For this purpose, neighbouring field stars of the Cepheids were observed, queried from the Gaia Data Release 3 catalog, with the FLAMES multi-object spectrograph. The instrument setup was such that, on average, 115 field stars were observed with the GIRAFFE spectrograph in MEDUSA mode and 2-7 field stars with the UVES spectrograph in the Red Arm mode. This release covers only the UVES data, as the ESO automatic reduction process covered the GIRAFFE spectra, which are available for download from the ESO Science Portal. The fibers fed to UVES have a diameter of 1 arcsec, and the cross-dispersed echelle spectroscopy provides a spectral resolving power of R=47,000.

The aim of the Expanding Horizons process is for ESO to gather input from the community to decide on its next major programme, following the completion of ELT construction. ESO has now formally opened the call for Letters of Intent (LoI) for the Expanding Horizons process with deadline 1 December 2026. The submission of a LoI is a requirement for submitting a proposal.

ESO received 1286 valid proposals for observations in Period 118 (1 May 2027 - 30 April 2028). The deadline for proposal submission was 22 September 2026. On the VLT, the most demanded ESO instrument was MUSE with a request of 7170 hours, followed by ESPRESSO (5873 hours), and XSHOOTER (4971) hours. HARPS/NIRPS on the ESO 3.6-m telescope was the most demanded instrument at La Silla, with a combined request of 4470 hours, followed by SOXS, with a combined request of 3045 hours.

ALMA is implementing the Wideband Sensitivity Upgrade (WSU) to address the ALMA 2030 Development Roadmap and keep ALMA at the forefront of astronomical discovery. The WSU will bring major observing improvements, including increased instantaneous bandwidth (by at least 2x), improved sensitivity, and higher spectral resolution across wider bandwidths than is currently possible with ALMA. To help ALMA assess user support needs over the next decade we invite your input via the following ALMA user survey.

ESO is delighted to announce the ESO workshops chosen to take place in 2027. These events will bring together astronomers from around the world to explore some of the most exciting frontiers in astrophysics. Fourteen proposals were submitted this year and reviewed by a panel of experts from ESO in Garching and Chile. After careful consideration, and with input from ESO's Programme Scientists, the top-ranked proposals were confirmed by the Heads of the Offices for Science and the Director for Science.

This ESO workshop will explore the extreme environments and physical processes associated with galaxy interactions and mergers across cosmic time. Galaxy encounters often give rise to some of the most spectacular star-forming events, rapid accretion and coalescence of supermassive black holes, and powerful feedback phenomena capable of transforming galaxies completely. The workshop will revisit the recent advancements in this key area of galaxy evolution research, from both observational and theoretical perspectives, and envision future directions enabled by the next-generation multi-wavelength wide-field facilities and surveys.

ESO is pleased to announce that the international conference "Probing the Cosmos with White Dwarf Binaries" will be held in person from 26 to 30 July 2027, at ESO's Headquarters in Garching bei München. This workshop will bring together researchers across the diverse sub-fields of white dwarf binaries to foster discussion in key areas, including: Galactic archaeology, binary evolution, pathways to Type Ia Supernovae, and multi-messenger & gravitational-wave sources.
