Knowra Sagittarius B2 Sagittarius B2 Sagittarius B2 is a massive molecular cloud complex near the Milky Way’s center. Its dense gas hosts active star formation and an unusually rich variety of interstellar molecules.
Molecular cloud : A dense region of interstellar gas and dust, composed mainly of molecular hydrogen and often associated with star formation. Sagittarius B2 is a particularly massive, chemically rich example of this type of cloud.
Astrochemistry : The study of chemical processes and molecules in astronomical environments. Sagittarius B2 is a key source for identifying interstellar molecules and studying their formation.
Sagittarius B2(N) : A northern star-forming region within the Sagittarius B2 molecular cloud complex. It is one of the cloud’s prominent sites of massive star formation and complex-molecule emission.
Galactic Center : The central region of the Milky Way, containing a dense concentration of stars, gas, dust, and a supermassive black hole. Sagittarius B2 lies in this crowded region, where its environment differs from that of nearby galactic-disk clouds.
Molecular hydrogen : The H₂ molecule, the most abundant molecule in molecular clouds but difficult to detect directly in cold gas. It makes up most of Sagittarius B2’s molecular gas, though astronomers often trace that gas with other molecules.
Hot molecular core : A compact, warm region of molecular gas surrounding a newly formed massive star. These regions within Sagittarius B2 expose complex molecules to heat from young stars.
Sagittarius B2(M) : A central, compact star-forming region within the Sagittarius B2 molecular cloud complex. Its embedded massive stars heat dense gas and produce bright molecular emission.
Sagittarius B2 region : A group of molecular and radio sources surrounding Sagittarius B2 near the Milky Way’s center. The wider region provides the galactic context for the cloud complex and nearby emission sources.
Dense core : A compact, high-density region within a molecular cloud where gravitational collapse can form stars. Sagittarius B2 contains dense regions where its extensive star formation takes place.
Massive star formation : The formation of stars substantially more massive than the Sun, often accompanied by intense radiation and outflows. Sagittarius B2’s active star-forming regions provide examples of this energetic process.
