  2. Why is there so little water left on Mars?

    Date de publication:

    24 Juin 2021

    Mars is known for its thin atmosphere, where CO2 dominates and provides most of the atmospheric mass and pressure. In fact, the pressure is similar to that in the Earth’s stratosphere, which is a layer of the atmosphere, at more than 30km above the surface.

  3. Glacier melting: untangling local from global

    Date de publication:

    12 Mai 2021

    An international team led by the LEGOS space geophysics and oceanography research laboratory has measured the evolution of all the world’s glaciers over 20 years. On average, they are losing 267 billion tonnes in ice mass a year, a cumulative loss of 4% in just 20 years. The authors confirm this phenomenon is accelerating globally as temperatures rise and explains certain slowdowns observed locally.

  8. Solar storms impact Earth’s neighbourhood

    Date de publication:

    16 Décembre 2019

    Fifteen years after they were first acquired, data from the Cluster mission continue to reveal new insights into the disturbances generated by solar storms when they hit Earth’s magnetosphere. For the first time, scientists have succeeded in measuring the complexity and amplitude of these magnetic wave disturbances using data from the CIS instrument on the four Cluster satellites.

  9. Saturn’s north polar hexagon

    Date de publication:

    19 Septembre 2018

    Analysis of data from the Cassini probe has revealed that a vortex towering more than 300 kilometres above Saturn’s north pole mirrors the famous hexagon cloud pattern observed lower in the planet’s atmosphere since 1980. Sandrine Guerlet from the LMD dynamic meteorology laboratory in Paris, who has co-authored a paper on this discovery, explains.

  19. Source of Saturn’s kilometric radiation revealed

    Date de publication:

    13 Novembre 2018

    Using data from the Cassini mission, scientists are unravelling the mechanisms that drive auroral radio emissions at Saturn’s poles, which are key to understanding certain characteristics of the giant ringed planet. Laurent Lamy, an astrophysicist at the LESIA space and astrophysics instrumentation research laboratory (Paris Observatory) and lead author of an article on the subject in the journal Science, gives us the details.
