Bipolar nebulae as a research area focuses on astrophysical objects exhibiting pronounced axial symmetry and two-lobed morphologies, typically arising from mass loss in evolved stars or from collimated outflows in young stellar objects. Studies investigate the shaping mechanisms of these nebulae, including binary interactions, magnetic fields, and anisotropic stellar winds, as well as the role of jets and disks in producing their characteristic bipolar structures. Research integrates high-resolution imaging, spectroscopic diagnostics, and hydrodynamical or magnetohydrodynamical modeling to constrain density distributions, kinematics, ionization structures, and evolutionary pathways, thereby informing broader theories of stellar evolution, feedback, and circumstellar medium dynamics.
Using NASA's SPHEREx space telescope, astronomers have observed remnants of the eruption of Nova Persei 1901. As a result, they detected a bipolar molecular hydrogen shell around this nova, which may be a large planetary ...
An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a complex planetary nebula known as NGC 6302. The observations, detailed in a paper published Feb. 25 on the arXiv pre-print ...
Two heads are better than one in the latest images from NASA's James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star. Nebula PMR 1 is a cloud of gas and dust that ...

By analyzing the data from the SuperCOSMOS Hα Survey (SHS) and from the Gaia satellite, astronomers have inspected a bipolar planetary nebula designated PHR J1724-3859. Results of the study, published Nov. 19 on the arXiv ...
Since the discovery of planetary nebulae in the late 1700s, astronomers have learned that these expanding shells of glowing gas expelled by low-intermediate mass stars late in their lives can come in all shapes and sizes. ...
