Question

Which of the following galaxy types is most likely to be clearly identifiable, regardless of orientation? SBc

Answer 1

Answer:

The most likely galaxy type to be identifiable regardless of orientation is: Irr

Explanation:

The Irr galaxies don't have a discernable or usual shape; that is why it is relatively easy to identify.

When we talk about E type galaxies, this statement proves itself by the way the cumulus of stars compounds the galaxy. The elliptical galaxies have the form of ellipses, with a reasonable distribution of stars. The degree of eccentricity is the number that complements the E letter; that's why E0 galaxies are almost spherical, while E7 is considerably elongated.

SBc, SBa galaxies are spiral; this means it can be flat in some angles difficulting their identification process; in this case, the last letter means the way the arms display their form, with "c" having a vague form and "a" well-defined arms. That's why in some angles can be mistreated as another type of galaxy.
