An area inside a star-forming molecular cloud. The background is covered with layers of gas and dust in blue, green and yellowish colors. Thicker clumps of cold dust, dark brown to black, block out light completely. Stars lie among and atop the clouds, from small orange ones to large white or blue ones. Waves and streams of glowing whitish gas are created by jets from protostars colliding with the surrounding material.This NASA/ESA/CSA James Webb Space Telescope Picture of the Month shows the giant molecular cloud Orion A, an area of the sky replete with star-forming clouds.ESA/Webb, NASA & CSA, T. Megeath, M. Zamani (ESA/Webb) Acknowledgement: M. H. Özsaraç This image, captured by NASA’s James Webb Space Telescope and released on June 5, 2026, shows just a small portion of one of the Orion Molecular Clouds, a long and massive filament of cold gas and dust beyond the Orion Nebula. Every stage of star formation — from the youngest stellar embryos to protoplanetary discs to newly-minted pre-main sequence stars — is contained within this scene which stretches 150 light-years across.
