The Messenger No. 175 Now Available

8 March 2019

The latest edition of ESO's quarterly journal, The Messenger, is now available online. Find out the latest news from ESO on topics ranging from new instruments to the latest science discoveries.

In this special issue of the ESO Messenger, several articles give an overview of the upcoming 4-meter Multi-Object Spectroscopic Telescope (4MOST).

4MOST is a new wide-field spectroscopic survey facility under development for the Visible and Infrared Survey Telescope for Astronomy (VISTA) at ESO’s Paranal Observatory in Chile. Paranal is one of the finest observing sites worldwide and provides access to astronomical objects in the southern hemisphere, such as the galactic center and the Magellanic Clouds. The 4MOST design allows tens of millions of spectra to be obtained via five-year surveys, even for targets distributed over a significant fraction of the sky.

Highlights of this edition include:

  • 4MOST: Project Overview and Information for the Call for Proposals - de Jong et al.
  • 4MOST Survey Strategy Plan - Guiglion et al.
  • 4MOST Consortium Surveys
  • The New ESO Phase 1 System - Phase 1 Project Team
