Serpentarius was historically recognized as a constellation representing a serpent, primarily through its association with the figure of Ophiuchus. Dating back to Ptolemy’s astronomical work, it distinguished itself by dividing the larger Serpens (the Serpent) constellation. This designation is now...

Barnard 68 is a Bok globule, a dense cloud of gas and dust within the Ophiuchus constellation. It’s notable for its dark appearance obscuring background starlight. Astronomers study this nebula to understand star formation processes and the conditions present in regions where new stars are born. It'...

B68 is a dark nebula and isolated Bok globule located in the southern constellation Ophiuchus. It is composed of dense molecular dust and gas that effectively blocks the light of background stars, creating a stark silhouette against the starfield. Astronomers have mapped its internal structure and d...

B72, widely known as the Snake Nebula, is a dark molecular cloud located in the constellation Ophiuchus. It is composed of dense, opaque cosmic dust that completely obscures the light from background stars, creating a distinct, winding S-shaped silhouette. The nebula was cataloged by astronomer Edwa...

Hb 5, also known as Hubble 5, is a planetary nebula in the constellation Sagittarius. It is recognized for a strongly bipolar form, in which opposing lobes extend from a denser central region, and for a prominent dark band produced by dust near the nebular waist. The structure is interpreted as the...
