Question

Which phrases accurately describe an elliptical galaxy? Check all that apply

Answer 1

An elliptical galaxy have a three dimensional spiral shape, the stars in these galaxy are seen to orbit around a center. The stars found inside these galaxies are very old and are of low masses. Almost negligible star formation takes place in these galaxies. The interstellar matter (gas and dust) is also negligible.

So, the correct statements about the elliptical galaxies are :

- May be spiral shaped

- Has no new stars being formed.

- Has almost no gas or dust between stars.

Answer 2

Elliptical galaxy is one of the three types of galaxies observed using large telescopes like the Hubble telescope. The elliptical galaxy is ellipsoidal in shape like an egg and rotates radially unlike spiral galaxies that rotate around a fixed centre. The elliptical galaxies are low on gas clouds and dust, thus lack star formations, and contains a lot of old aged stars. This feature leads the scientists to believe that it is the last phase in the life of galaxy.

Hence the correct options are:

1. may be egg-shaped

2.has no new stars being formed

3.has almost no gas or dust between stars
