2011-02-03 Peut-on valablement construire des modèles de formation des systèmes planétaires d'après l'étude de notre seul système solaire? Une étape décisive a été franchie grâce aux techniques à haute résolution angulaire capables de sonder les systèmes planétaires en formation autour d’étoiles autres que notre Soleil.
2009-11-10 A European Space Agency project, the Darwin mission should be able to directly observe planets similar to ours and even characterise their atmospheres. Ultimate objective? To detect life elsewhere in the universe.
2006-04-11 The observation of the immediate vicinity of a star other than the Sun has just been carried out for the first time. A debris disc made up of hot (1300 degrees) dust grains, residues of comet evaporation and collisions between asteroids, was indeed detected for the first time around Vega. This discovery is the work of an international team, which includes researchers of Paris Observatory (LESIA).

2003-07-16 Using the ESO 3.6-m telescope at La Silla (Chile), an international team of astronomers  has discovered a complex cosmic mirage in the southern constellation Crater (The Cup). This "gravitational lens" system consists of (at least) four images of the same quasar as well as a ring-shaped image of the galaxy in which the quasar resides - known as an "Einstein ring". The more nearby lensing galaxy that causes this intriguing optical illusion is also well visible.
1996-02-09 One more cosmic mirage has been found with the ESO 3.5-metre New Technology Telescope (NTT). It consists of two images of the same quasar, seen very close to each other in the southern constellation of Hydra (The Water-Snake).
1993-06-03 Although astronomy is an exact natural science, chance sometimes plays an important role. The recent discovery during an otherwise routine observation of the hitherto brightest known double quasar  would not have been possible without some luck.
1991-10-22 Observations with telescopes at the La Silla observatory have revealed that the image of an extremely distant quasar, known as Q1208+1011, actually consists of two images very close to each other. It is the most distant and also the brightest quasar ever observed to have a double image.
1988-07-28 Thanks to observations performed under near-perfect conditions at the La Silla observatory, it has been possible to show that the image of a distant quasar consists of no less than four components. Most appropriately, the object has now become known as the cloverleaf quasar. The peculiar image is due to the effect of "gravitational lensing", a phenomenon predicted by Einstein's General Theory of Relativity and explained at the end of this Press Release.
1987-10-22 The discovery of a new gravitational lens system in the southern constellation Cetus comes as a first exciting and fundamental result obtained by a group of European astronomers in the frame of the systematic search program they are carrying out at the ESO La Silla observatory. Not only did they find that the image of the highly luminous quasar (ESO8712 and ESO8713) UM673 is double, but they were also able to observe the distant galaxy that is responsible for this effect. Continued monitoring of this rare object may actually lead to cosmologically significant results about the size and the age of the Universe.
