Advanced Telescopes Reveal Hidden Worlds Orbiting Bright Stars
Astronomers combined Gaia and GRAVITY data to image dim objects near bright stars, potentially revolutionizing the search for nearby exoplanets. Detecting faint objects close to…
ESA’s Gaia satellite, launched by the European Space Agency in December 2013, is a space-based observatory with a mission to create the most precise and comprehensive 3D map of the Milky Way galaxy. Gaia is tasked with measuring the positions, distances, and motions of billions of stars with unprecedented precision. Its objective is to provide a detailed understanding of the structure and dynamics of our galaxy and to answer fundamental questions about its origin and evolution. Gaia’s observations also contribute to the study of other celestial phenomena such as asteroids within our solar system, stars with planets, and distant galaxies. Additionally, Gaia’s data is instrumental in testing theories of gravity and the general structure of the universe. The satellite operates from a point known as the second Lagrange point, or L2, which provides a stable environment for its sensitive measurements. Through its mission, Gaia not only enhances our understanding of the cosmos but also plays a crucial role in advancing the field of astrometry.
