James Webb Space Telescope (JWST) imaged Sharpless 2-284 (Sh2-284), an eight-light-year stellar jet from a massive star forming on the Milky Way's outskirts. The straight, collimated jets, powered by a star ten times the sun's mass, contradict theories suggesting chaotic formation in massive stars. This low-metallicity environment mirrors the early universe, offering insights into massive star formation. The jets' structure, including filaments and bow shocks, reveals the star's growth over 100,000 years. Eventually, the star will supernova, enriching space with heavy elements.
