Question

1. categorize the data table lists descriptions of three different galaxies. complete the table by filling in the type of each galaxy. then identify which galaxy in the table is most like our own in structure.

Explanation:

Step1: Recall galaxy types

There are three main types of galaxies: spiral, elliptical, and irregular.

Step2: Match descriptions to types

• Spiral galaxies have a structure that looks like a pinwheel with arms that curve out from the center. So, Andromeda is a spiral galaxy.
• Elliptical galaxies look like a flattened ball. So, NGC 4150 is an elliptical galaxy.
• Irregular galaxies have stars, dust, and gases that are randomly scattered. So, Large Magellanic Cloud is an irregular galaxy.

Step3: Identify galaxy like the Milky Way

The Milky Way is a spiral galaxy. Among the given galaxies, Andromeda is a spiral galaxy.

Answer:

Galaxy Name	Description	Type
NGC 4150	looks like a flattened ball	Elliptical
Large Magellanic Cloud	stars, dust, and gases (looks like randomly scattered)	Irregular

The galaxy in the table that is most like our own (the Milky Way) is Andromeda (since the Milky Way is a spiral galaxy and Andromeda is classified as a spiral galaxy).
