ORION CLOSE-UP. Four detailed views of the Orion star-forming region. Left image: Dark-red column shows the edge of the cavity carved by the ultraviolet light emitted by the Trapezium. Second image: Faint red stars are brown dwarfs, objects too lightweight to burn as stars. This portrait for the first time shows brown dwarfs in Orion in visible light. Third image: Glowing region reveals arc and bubbles formed when stellar winds emanating from the Trapezium stars collide with interstellar material. Right image: Dense, dark pillars of dust and gas—the homes of embryonic stars—are being eroded by intense ultraviolet light from the Trapezium stars.
