    Lucky alignment of two spacecraft reveals how solar wind gets a magnetic push! ☀️ #shorts

    Fast’ solar wind moves with speeds above 500 km/s. Curiously, this wind exits the Sun’s corona with lower speeds, so something speeds it up as it moves farther away. The million-degree wind naturally cools down as it expands into a larger volume and becomes less dense, much like the air on Earth as you climb a mountain. And yet, it cools more slowly than expected from this effect alone.

    So, what provides the necessary energy to accelerate and heat the fastest parts of the solar wind?

    Data from our Solar Orbiter and NASA’s Parker Solar Probe have provided conclusive evidence that the answer is large-scale oscillations in the Sun’s magnetic field, known as Alfvén waves.

    Data collected using the NASA/ESA/CSA James Webb Space Telescope, combined with earlier observations from the NASA/ESA Hubble Space Telescope, show surprisingly little methane (CH4) in the atmosphere of WASP-107 b, indicating that the interior of the planet must be significantly hotter and the core much more massive than previously estimated.

  • Calling all space detectives to hack an exoplanet!

    Calling all space detectives to hack an exoplanet!

    Clever space detectives, we need your help! We’ve got a case on our hands, of two mysterious exoplanets, and we need your help to profile them. Find out how you can use real satellite data to investigate an alien planet and become an exoplanet detective in the first ever ESA Education student hackathon.

    Join us for this exciting new event featuring experts such as Didier Queloz, the 2019 Nobel Laureate in Physics and Kate Isaak, ESA project scientist for the Cheops mission.
