The year 2012 marks the 50th anniversary of the founding of the European Southern Observatory (ESO).
ENGADGET: 9-gigapixel image of the Milky Way reminds us just how small we truly are
The European Southern Observatory is organising a public effort to measure the astronomical unit the old fashioned way, just for fun.
The facility is run by the European Southern Observatory (Eso) organisation.
In this case, astronomers using the European Southern Observatory's 2.2m telescope at La Silla and Very Large Telescope at Paranal (both in Chile) targeted the afterglow.
The telescope is operated by the European Southern Observatory (Eso) organisation, which oversees the La Silla facility and the Very Large Telescope (VLT), which is also in Chile.
HARPS, which sits on the European Southern Observatory's 3.6-meter telescope in Chile, allows researchers to detect the tiny gravitational wobbles that orbiting planets induce in their parent stars.
In December, Dr Mumma's team will begin another study of the Martian surface using the new technique of adaptive optics at the European Southern Observatory's Very Large Telescope (VLT) in Chile.
Timothy Davis of the European Southern Observatory and colleagues made use of the Carma array of telescopes in California, US, looking specifically for the radiation coming from molecules of carbon monoxide.
Both are operated by the European Southern Observatory (Eso).
Mr Mawet and his team, meanwhile, are trying to fabricate prototypes of their design to test on the European Southern Observatory's Very Large Telescope in Chile, which is at a higher altitude, and thus less prone to wobbling air.
ECONOMIST: A way to detect Earth-sized planets around other stars
Rafael Eufrasio of the Catholic University of America and Nasa's Goddard Space Flight Center and colleagues from the University of Sao Paulo in Brazil and the European Southern Observatory in Chile were interested in a number of regions away from the galaxy.
