An article published in the journal “Astronomy and Astrophysics” reports the first direct observation of an exoplanet using the technique of optical interferometry. The GRAVITY collaboration, so called because the researchers who belong to it manage the work of the instrument with the same name installed on ESO’s Very Large Telescope Interferometer (VLTI), observed the exoplanet HR 8799 e, a super-Jupiter that has a atmosphere containing clouds rich in iron and silicates that swirl around in a storm that crosses the entire planet.
