Webb captures stars in the early stages of life in a nearby stellar nursery

The NASA/ESA/CSA James Webb Space Telescope continues to reveal hidden parts of the cosmos with its advanced suite of infrared instruments. In a newly released image, Webb revealed many stars previously hidden by the dust clouds of NGC 7129, a stellar nursery about 3,300 light-ye

Webb image reveals young stars brewing in a nebulous cauldron

In this Picture of the Month from the NASA/ESA James Webb Space Telescope, we visit a turbulent cauldron of star formation to see what is brewing inside dense clumps of gas. This is a star-forming region named LHA 120-N 159, or simply N159, located 161,000 light-years away in the
