Packed into the centre of this region are bright lights of the Trapezium stars, the four heftiest stars in the Orion Nebula. Ultraviolet light unleashed by these stars is carving a cavity in the nebula and disrupting the growth of hundreds of smaller stars. The dark speck near the bottom, right of the image is a silhouette of an edge-on disk encircling a young star. Another whitish-looking disk is visible near the bottom, left, just above the two bright stars. This disk is encased in a bubble of gas and dust.
