Question

What causes arcs of light seen by scientists looking at the galaxy with a telescope?(1 point)
Responses

Light produced by a number of stars in the galaxy join together being pulled in by gravity. This is referred to as an "arc of light."

Large galaxy clusters containing both dark matter and normal matter. The immense gravity of all this material warps the space around the cluster, causing the light from objects located behind the cluster to be distorted and magnified.

The light from the stars of a distant galaxy bends the light and so the arcs of light seen through telescopes.

Answer 1

Correct answer: "Large galaxy clusters containing both dark matter and normal matter. The immense gravity of all this material warps the space around the cluster, causing the light from objects located behind the cluster to be distorted and magnified."

Explanation: This phenomenon is gravitational lensing — massive clusters bend spacetime so light from a background galaxy is stretched into arcs or rings (Einstein rings). The other choices are incorrect.
