These NASA/Hubble images are thought to be planetary proplyds, or the beginnings of planets surrounding stars in the Orion nebula. Their press release says,
"The brighter discs are indicated by a glowing cusp in the excited material and facing the bright star, but which we see at a random orientation within the nebula, so some appear edge on, and others face on, for instance. Other interesting features enhance the look of these captivating objects, such as emerging jets of matter and shock waves."
You can tell that many of these objects appear to be toruses surrounding stars. One image in particular resembles a developing zygote--look at the fourth row down and the fourth image in from the left. You can clearly see the opening at the top of the torus and can easily imagine the toroidal funnel going down to the center and out the bottom.
Now compare the image above to this image of a developing mouse embryo. It appears that a similar dynamic mechanism is involved in both cases.
In 2018 I posted this article on the torus of a newly forming planet, which you can access here.MIT researchers were surprised to discover that the swirling patterns precisely mirror other systems, from atmospheric hurricanes to ocean circulation hydrodynamics to quantum fluids.
