  • Hunting molecules to find new planets
    on June 18, 2018 at 3:30 pm

    It's been impossible to obtain images of an exoplanet, so dazzling is the light of its star. However, astronomers have the idea of detecting molecules that are present in the planet's atmosphere in order to make it visible, provided that these same molecules are absent from its star. Thanks to this innovative technique, the device is sensitive to the selected molecules, making the star invisible and allowing the astronomers to observe the planet. […]
