bipolar nebula

It is a spectral bipolar nebula.

This bipolar nebula takes the peculiar form of twin lobes of material that emanate from a central star.

A bipolar nebula is a distinctive nebular formation characterized by an axially symmetric bi-lobed appearance.

They both have point-like bright nuclei, are narrow-waisted bipolar nebulae, and share surprisingly similar spatially dependent spectra.

The first images of this bipolar nebula, taken using the Mt. Palomar Hale telescope in California, were released in April 2007.

Bipolar outflows may be associated with protostars (young, forming stars), or with evolved post-AGB stars (often in the form of bipolar nebulae).

M57 is an example of the class of planetary nebulae known as bipolar nebulae, whose thick equatorial rings visibly extend the structure through its main axis of symmetry.

Diffraction-limited speckle images of it in visible and near infrared light reveal a highly symmetric, compact bipolar nebula with X-shaped spikes which imply toroidal dispersion of the circumstellar material.

V1429 Aquilae is not only a Be star but also a Luminous Blue Variable candidate due to its high luminosity and later studies have shown it's actually a binary system surrounded by a disk of gas as well as a very extensive bipolar nebula.
