Red Supergiants in the Dragon Arc: Learn how JWST is shedding light on red supergiants in the Dragon Arc galaxy—ancient stars nearing the end of their lives. These stellar giants are offering unprecedented insights into the early universe and the evolution of galaxies over billions of years. The Mystery of Dark Matter: Delve into the shadowy realm of dark matter, which accounts for roughly 85% of the universe’s mass. While it remains unseen, its presence is felt through its gravitational effects, warping light around cosmic objects and shaping the structure of the universe. A New Era of Cosmology: Understand how these groundbreaking discoveries are rewriting the rules of cosmology, challenging our understanding of galaxy formation, stellar behavior, and the very fabric of the universe.Join us as we decode the secrets of the cosmos and explore how JWST is transforming our view of the universe—one star, one galaxy, and one mystery at a time.🌌🔭 The universe is speaking, and JWST is helping us listen.
