Question

Which phrase describes an irregular galaxy?

has a round shape
contains many young stars
has arms that extend from the center
is larger than other types of galaxies

Answer 1

Explanation:

An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. ... Irregular galaxies may contain abundant amounts of gas and dust.

Answer 2

Option B) contains many young stars

• The answer is "a significant collection of stars, gas, and dust locked together by gravity" because the galaxy is made up of millions or even billions of stars, gas, and dust.
• Unusual Galaxy. A galaxy with an ill-defined shape; irregular galaxies are frequently seen close to larger galaxies and have a lot of young stars and gas.
• The most peculiar galaxies are irregular galaxies. Neither the spiral galaxy nor the elliptical galaxy categories seem to apply to them. They lack attractive spiral arms, but they do contain ominous gas and dust patches.
• They were bent into their current peculiar shapes by gravitational interactions as a result of their close proximity to our galaxy. It appears that galaxy mergers have produced additional irregular galaxies.
• They are often bluer in colour than the arms and discs of spiral galaxies and lack both visible symmetry and a clear core centre.
