Large ground-based intruments will also be involved in the exploration of exoplanets in the future :

  • VLTI : this network will be operational at the end of 2006. It will combine the four 8.2 meter telescopes of VLT with four additional 1.8 meter telescopes. The beams of the 8 telescopes will be recombined in a coherent way. Thus the VLTI will be the most powerful interferometer in the world. With this instrument, astronomers will study the details of the surfaces of the stars and probe the protoplanetary disks. The VLTI will also allow for the detection of real Jupiter equivalents around stars located at 200 pc. http://www.eso.org/projects/vlti/
  • Atacama Large Millimeter Array (ALMA) is a collaboration between Europe and the United States to build a network of millimetric radiotelescopes. It will be used to make very precise astrometric observations and, probably, to detect exo-atmospheres. http://www.eso.org/projects/alma/science/planets.html
  • ELT-Owl : The Extremely Large Telescope project of the ESO (OWL) is a 100 meter telescope, working in the near infrared and visible wavelengths. http://www.eso.org/projects/owl/
