A new space telescope is set to launch in 2023 that will revolutionize how we observe the universe. The European Space Agency’s (ESA) Advanced Telescope for High-Energy Astrophysics (ATHENA) will be the largest X-ray telescope ever sent into space, and it promises to unlock some of the universe’s greatest mysteries. ATHENA will have unprecedented sensitivity, enabling it to detect the faintest X-ray sources and peer into the depths of the universe. It will help us detect the first black holes, uncover the nature of dark matter and dark energy, and observe the most powerful phenomena in the cosmos. In short, ATHENA will be a game-changer for astrophysics.
