hot, dense, slowly cooling sphere of carbon

dense core of neutrons that remains after a supernova

cloud of gas and dust, where stars form

states that the universe began from one point billions of years ago and has been expanding ever since

A student is shown a picture of a large number of stars clumped together without a discernible shape. The student argues that these stars cannot be a galaxy because all galaxies have familiar shapes such as elliptical and spiral. Is the student correct?

No. The stars could be part of an irregular galaxy.

Yes. These stars cannot be a galaxy if they do not form a familiar shape.

The stars cannot be a galaxy, but the student incorrectly lists "elliptical" as a possible shape. All galaxies are spiral.

Although all galaxies have familiar shapes, no single image can capture an entire galaxy. If the student could see the entire galaxy, it would have a familiar shape.
