From today, The Economic Times describes the Heliosphere as 'spherical' ( hence the name )
It goes on to say that the shape of the Heliopause is 'ever fluctuating.'
A 'spherical' Heliosphere implies a 'spherical' Heliopause, by definition.
Maybe some people like The Economic Times shouldn't report on astronomical issues.
Their reporting is 'confusing.'
Voyager-I is the only space probe to cross the Heliopause, and it crossed at a single location. It never 'saw' the Heliopause, it's just that JPL noticed a jump in cosmic radiation as Voyager passed into interstellar space.
The Heliopause is a 'theoretical' boundary, never actually seen!
