Question

use the text to compare and contrast galaxies and nebulae. nebulae and galaxies are two types of celestial objects. most are so far away that they can be seen only with a telescope, but astronomers can gather enough information to tell them apart. a nebula is a cloud of interstellar dust particles and ionized gases, while a galaxy is a large collection of stars held together by gravity. one of the main differences between the two is their size. a galaxy is generally much larger than a nebula. in fact, a galaxy can contain a nebula, but a nebula cant contain a galaxy. when a large amount of mass builds inside a nebula, the gravitational attraction increases, and the nebula collapses to form a star. however, while galaxies contain stars, a galaxy as a whole will not collapse to form a star. in addition, galaxies are found in clusters or groups in space, but nebulae havent yet been observed in these patterns. galaxies nebulae are celestial objects are collections of stars collapse to form stars have been found in clusters

Explanation:

The text states that both galaxies and nebulae are celestial objects. Galaxies are large collections of stars held by gravity, not collapsing to form stars themselves, and are found in clusters. Nebulae are clouds of interstellar dust and ionized gases, can collapse to form stars, and haven't been observed in clusters.

Answer:

Are celestial objects:

• Galaxies: Yes
• Nebulae: Yes

Are collections of stars:

• Galaxies: Yes
• Nebulae: No

Collapse to form stars:

• Galaxies: No
• Nebulae: Yes

Have been found in clusters:

• Galaxies: Yes
• Nebulae: No
