  2. QUE DE LUNES !

    Publishing date:

    May 14, 2020

    Notre Lune n’est pas le seul satellite naturel du système solaire. Certaines planètes comme Saturne et Jupiter en possèdent des dizaines ! Pourquoi ont-elles cette forme ? Comment interagissent-elles avec leur planète ? Pourraient-elles abriter de la vie ? Des missions, comme les projets MMX (JAXA - DLR/CNES) vers les lunes de Mars ou JUICE (ESA) vers Jupiter, visent à lever ces mystères.

  4. Huygens- Landing on Titan

    Publishing date:

    September 11, 2017

    In December 2004, the U.S. Cassini spacecraft released the European Huygens module for the most-distant landing yet accomplished in the history of space exploration. Titan, Saturn’s largest moon, was the target and the high point of this collaboration that has brought great discoveries in planetology. With the Cassini mission now set to end, Athéna Coustenis, research director at the LESIA space and astrophysics instrumentation research laboratory at the Paris Observatory, looks at what it found there.

  5. Cassini reveals giant dust storms on Titan

    Publishing date:

    October 5, 2018

    These giant dust storms seen at the equator on Titan rise as far as 10 kilometres above the surface. Mars and Earth are no longer the only worlds in the solar system where such phenomena are known to occur. We put three questions to Sébastien Rodriguez, a planetologist at the IPGP global physics institute in Paris and lead author of this discovery published in the journal Nature Geoscience on 24 September.

    June 3, 2009

    A black hole of more than 500 times the Sun's mass was discovered. It is an intermediate one between the stellar and super-massive black holes. This "missing link" just got discovered by an international team led by investigators of the Centre for the Study of Radiation in Space of Toulouse. This world-first discovery was achieved thanks to observations of ESA's XMM-NEWTON satellite. This result was announced in the July 2nd, 2009 issue of Nature.

    Publishing date:

    September 6, 2017

    In the space of 13 years, Cassini observed Saturn and devoted a lot of attention to its moons. With the mission now about to end, Patrick Michel, astrophysicist, planetologist and research director at the Côte d’Azur Observatory in Nice, reflects on the discoveries it has made about the planet’s natural satellites.

  9. Cassini-Huygens mission- Titan one year on

    Publishing date:

    January 10, 2006

    Cassini-Huygens is the 1st space mission dedicated to exploring Saturn and its system of rings and moons. One year ago today, Europe’s Huygens probe separated from the Cassini orbiter and landed on Titan, Saturn’s largest moon. What have its findings taught us about this tantalizing new world?

  10. Huygens, le choc de Titan

    Publishing date:

    September 11, 2017

    En décembre 2004, la sonde américaine Cassini envoyait le module européen Huygens vers le sol le plus lointain jamais atteint par l’exploration spatiale. Titan, la plus grande lune de Saturne, a été le point d’orgue de cette collaboration qui a amené à de grandes découvertes en planétologie. À l’occasion de la fin de mission de Cassini, retournons sur Titan avec Athéna Coustenis, directrice de recherche CNRS au LESIA, à l’Observatoire de Paris.

    August 6, 2003

    Comme beaucoup d’autres planètes, Saturne peut être confondue depuis la Terre avec une étoile. A plus d’1 milliard de km de la Terre, c’est la plus lointaine planète connue des Anciens. L’invention de la lunette et du télescope a permis à de nombreuses générations d’astronomes d’étudier cet astre aux anneaux énigmatiques.
