The meaning of STELLAR NEBULA is the nebulosity surrounding a star : a star's shell or envelope of nebulosity.

This cloud becomes a flat, spinning disk, called a solar nebula. In the middle of this disk, a baby star forms and gathers material around it. Small particles in the disk stick together and make bigger pieces, like building blocks, which turn into baby planets. When the baby star gets ...
Another iconic region is the Eagle Nebula, known for its "Pillars of Creation." These massive columns of gas and dust clouds are bustling with star-forming activity. As stars live and die, they enrich the interstellar medium with heavier elements, ensuring that the next generation of stars and...
a symbiotic binary star that lies only roughly 1,000 light-years from Earth in the constellation Aquarius. This is a type of binary star system consisting of a white dwarf and a red giant that is surrounded by a large, dynamic nebula.NASA, ESA, M. Stute, M. Karovska, D. de Martin...
Using NASA's Chandra X-ray Observatory, astronomers have identified 152 X-ray sources, including 95 new young stellar objects (YSOs) in Serpens South star-forming cluster. The finding is detailed in a paper published April 13 in the arXiv pre-print serve
We have detected with the Infrared Space Observatory (ISO) the mid-infrared emission associated with the Class 0 protostar VLA1 in the HH1-2 region located in the Orion nebula. The emission arises in the three wavelength windows at 5.3, 6.6 and 7.5 micras where the absorption due to ices...

reasonable primordial contributions and leads to predicted abundances in the presolar nebula and/or the present interstellar medium in excess of the observationally inferred values. This result, which obtains even for zero primordial D and 3 He, and was anticipated by Rood, Steigman & Tinsley (...
