    Date de publication:

    24 Juin 2013

    After a mission that lasted twice as long as planned, CNES’s CoRoT spacecraft—capable of listening to the music of the heavens and hunting for exoplanets—is to be retired from service. Its remarkable haul of results has enabled scientists to progress from detecting exoplanets to studying them in close detail, while opening a new window into the inner workings of stars.

    Date de publication:

    27 Décembre 2006

    Three months after launch, CNES’s COROT stellar seismology and exoplanet hunting mission is poised to reach a highly symbolic milestone. In a few days’ time, the project team that has watched over the satellite from its design stage will hand over to controllers tasked with operating it through to the end of the mission.

  14. COROT discovers its first exoplanet!

    Date de publication:

    27 Décembre 2006

    It’s called CoRoT-Exo-1b, spans a diameter of between 200,000 and 250,000 km and completes an orbit of its parent star in just 1½ days. But for the engineers and scientists involved in the COROT project, it is much more than that, providing spectacular proof that the satellite they spent years developing is operating like clockwork and is now set to go on to even greater things.

    Date de publication:

    30 Mai 2008

    COROT recently discovered 2 new gas-giant exoplanets and an unknown celestial object, taking the total of exoplanets it has found to 4. Other signals detected by the satellite could also indicate the existence of another exoplanet with a radius 1.7 times that of Earth’s.
