The European Space Agency (ESA) is dedicated to advancing Europe’s space capabilities, ensuring that investments in space technology deliver benefits for citizens across the continent and worldwide. The agency works closely with its member states’ national agencies, institutions, and organizations.
ESA’s mission encompasses various areas, including exploring our Solar System, protecting life and infrastructure on Earth, utilizing space to benefit citizens, making space accessible, and addressing future challenges. One notable endeavor is ESA’s Jupiter mission, set to swing through the Earth system this summer.
Recently, NASA/ESA/CSA collaborated on a groundbreaking observation using the James Webb Space Telescope (JWST), revisiting a legacy field made famous by the Hubble Ultra Deep Field. The JWST captured an extraordinary image of thousands of distant galaxies, some dating back to the earliest periods of cosmic history. This unprecedented view has revealed over 2,500 sources in the MIRI Deep Imaging Survey region and provided insights into galaxy formation and evolution.
Astronomers can now study the growth and evolution of these galaxies using JWST’s sharp resolution, even at mid-infrared wavelengths. The image highlights fine distinctions between different types of infrared light, enabling researchers to distinguish features such as high concentrations of dust or active galactic nuclei (AGN). By revisiting this legacy field, JWST is expanding our understanding of the first cosmic structures and uncovering previously hidden galaxies.
This discovery builds upon a tradition initiated by the Hubble Space Telescope, allowing for new details to be revealed and fresh insights into the universe’s formation.
