Cat's Paw Nebula
The Cat's Paw Nebula is one of the most active stellar nurseries in the sky, and dust hides most of its young stars.

In July 2025 Webb marked its third year of science operations with a near-infrared look inside the Cat's Paw Nebula. NGC 6334 is a star-forming region about 4,000 light-years away in Scorpius. This frame is one section of it. John Herschel first glimpsed it from the Cape of Good Hope in June 1837, and the telescopes of the day showed him only the brightest toepad.
Blue patches glow at the centre, ringed by brown-orange dust. Either side of the bright patch at top centre, dark zones run short of stars; gaps like those mark dense foreground dust, home to stars still forming and blocking the light of the stars behind. Small red clumps lie scattered through the dust, redder than the yellow-white stars beside them. Each one marks massive star formation under way out of sight.
