The object is likely an expanding cloud of ionized gas. Charged particles move preferentially along magnetic field lines. The fact that it is not oblate may indicate a very low local magnetic field strength. Or, it could be oblate but with the axis pointed at us.

If it’s an expansion coming from a source, the expansion must have had a much higher velocity then the source velocity. To remain spherical.

A paradox for all matter moving. Like long straight lines.

The second is the density. Doesn’t appear to be much of a gradient. And does appear to be thin thru-out.

A sphere of gas would be denser in the center.

There seems to be many filaments in the area, perhaps it’s a closed filament.
