NASA’s Webb Captures Commotion From Nebula’s Stellar Jets

A young star cluster filled with many stars that display Webb’s unique eight-pronged diffraction pattern. At its center is a yellow star that sports the largest diffraction pattern. To its left, there is a region filled with yellow dust and gas that extends from the star to the left and the bottom, covering about two-thirds of the frame. The yellow region has several embedded blue stars of different sizes. The top third, which lies outside the yellow region, has a few bright protostars, within dense gray gas. These stars illuminate the gas, making it appear blue. A few red outflows from other protostars are visible above this grayish-blue region. To the right of the central star, there is a clumpy, flame-like plume of red dust and gas with protostars that emit a soft white light within. The plume is surrounded by more dense gray gas and dust. It is about one third the size of the yellow region. There are several background galaxies strewn throughout.

NASA’s James Webb Space Telescope has revealed many protostars and stars within the glowing gases of NGC 7129. Hot, atomic hydrogen gas is shown here in the golden region, while cooler, molecular hydrogen gas, shocked by embedded protostars, is represented in red.

A cauldron of cosmic creation is being revealed in a new image from NASA’s James Webb Space Telescope. Webb has unveiled numerous stars formerly hidden by clouds of dust in a stellar nursery known as NGC 7129, which resides about 3,300 light-years from Earth.

Stars, the engines of elemental creation, have life cycles that begin with their birth in molecular clouds – cold, dense regions of dust and gas. Because of these dusty cocoons, young stars are often impossible to view by many telescopes, particularly those incapable of capturing infrared light. Webb, however, has a high degree of infrared sensitivity, allowing astronomers to peer through that dust and study the beginning of the star life cycle.
