ESO holds a leading position in astronomy education and outreach, partly thanks to the steady production of stunning, high quality astronomical pictures. The current standard of quality of the images and the publication rate, together with the current promotion strategy and the promotion of incredible scientific results, have led to a steady increase in ESOò??s visibility, and enhanced public awareness of ESOò??s highly competent armada of astronomical facilities.

The majority of the published pictures are based on the content of ESOò??s Science Archive, where data collected by the organisationò??s telescopes are stored. However, ESO telescopes are scientific instruments, so most of the data that they produce are not suitable for the purposes of making colour images. Astronomers at ESOò??s education and Public Outreach Department (ePOD) have systematically searched the Science Archive, and most of the datasets that could be used for producing colour images have now been published in our online gallery of images.

To keep up the current flow of spectacular astronomical images, periodically released as Photo Releases and Pictures of the Week, ePOD has decided to launch a new initiative: the Cosmic Gems Programme. This is aimed at obtaining images with the ESO telescopes for the purposes of education and public outreach, and will allow ESO to maintain its world-leading position in this field.

This is a similar strategy to that adopted by the very successful Heritage programme, which has been acquiring spectacular high quality outreach images from the Hubble Space Telescope since 1997.

The first image (eso1131) to come out of the Gems Programme shows a peculiar pair of galaxies ò?? and it is a stunning testament to the optical quality of the VLT and the skies over the Paranal Observatory [1]. The second image is the Lambda Centauri Nebula.

As part of the Gems initiative, ESOò??s Director General has granted dedicated observing time for outreach purposes as part of the ESO Directorò??s Discretionary Time programme. The small amount of time provided is mostly ò??low-grade timeò?? ò?? when the clouds roll in or there are moonlit skies not requested for science observations, and the telescopes might otherwise be idle. This means that the programme has a minimum impact on scientific observations, but is still capable of producing images of high visual impact.

The instruments and telescopes used as part of this initiative include the VIMOS and FORS2 spectrographs on the VLT at the Paranal Observatory, and the Wide Field Imager on the 2.2-metre MPG/ESO telescope at La Silla.

The objects targeted by this programme are selected from a series of astronomical catalogues and lists of beautiful objects. The team responsible for the project chose the most visually attractive, or particularly interesting or intriguing, objects. Care was also taken to ensure there was no similar image already available in ESOò??s outreach archive or from other professional or amateur telescopes.

The images will be released to the public as they become available. The data collected are made available to professional astronomers through the Science Archive.
