- New James Webb Space Telescope (JWST) image shows infant stars (protostars) in FS Tau region, celebrating independence from molecular clouds.
- NASA released image commemorating U.S. 250th anniversary, depicting protostars becoming full stars via nuclear fusion of hydrogen to helium.
- Protostars form from collapsing clumps in molecular clouds, gathering material until triggering fusion, defining main-sequence stars.
- JWST's infrared power reveals FS Tau protostars in detail, 450 light-years away, aiding study of low-mass star evolution.
- Research investigates radiation and outflows from low-mass stars affecting environment, with JWST showing episodic matter accretion.
- Blue ridges in image indicate gas shunted by protostar outflows, creating dense regions reflecting light, resembling cosmic fireworks.
