ESO Science Announcements

Imaging of Stellar Surfaces

Published: 19 Sep 2017

ESO Headquarters, Garching, Germany, 5–9 March 2018

There have been tremendous recent advances in observational techniques enabling resolution of the surfaces of stars other than the Sun. Current and planned VLTI instruments, SPHERE on the VLT and ALMA, as well as other interferometric facilities, have recently succeeded in resolving stellar surfaces. The workshop aims to bring together observers from different techniques and wavelengths, and theoreticians working on stellar atmospheres and stellar structure.

ESO Public Spectroscopic Surveys with ARO Telescopes

Published: 14 Sep 2017

ESO is offering the possibility of conducting Public Spectroscopic Surveys using the telescopes of the Arizona Radio Observatory, as part of an agreement with the University of Arizona. Public Surveys are observing programmes for which proposers collect and make publicly available, within a defined time, a fully reduced and scientifically usable data set that is likely to answer a major scientific question, and be of general use and broad interest to the astronomical community. The deadline for submitting Public Surveys proposals with the ESO ARO time is 19 October 2017.

Call for Proposals for Period 101

Published: 31 Aug 2017

The Call for Proposals for observations at ESO telescopes in Period 101 (1 April 2018 – 30 September 2018) has been released. Please consult the Period 101 document for the main news items and policies related to applying for time on ESO telescopes. All technical information about the offered instruments and facilities is contained on ESO webpages that are linked from the Call. The proposal submission deadline is 12:00 CEST 28 September 2017.

Period 101 Changes in ESO Scientific Categories A and B

Published: 30 Aug 2017

Astronomers applying for time in Period 101 should note that the Observing Programmes Committee (OPC) scientific subcategories belonging to Categories A and B have been redefined. In addition, Category A is now called "Cosmology and the Intergalactic Medium" (previously "Cosmology") while Category B has been renamed "Galaxies" from "Galaxies and Galactic Nuclei". The full updated list of A and B subcategories is available on the OPC Categories page and in the ESOFORM User Manual.

ESO Postdoctoral Fellowships

Published: 28 Aug 2017

ESO’s prominent postdoctoral fellowship programme in both Garching (Germany) and Santiago (Chile) offers outstanding early-career scientists the opportunity to further develop their independent research programmes. From exoplanets to cosmology, observational, theoretical and fundamental astrophysics, these are all areas where ESO Fellows can benefit from a highly dynamic scientific environment, at some of the most advanced ground-based telescopes in the world.
