Question

A scientist, using a telescope, sees arcs of light around a galaxy. In 3–5 sentences, explain the cause of the arcs of light.

Answer 1

Answer: Gravitational lensing

Explanation: The arc that was seen around the galaxy by the scientist was caused by gravitational lensing; this is when a light dip and curves in the presence of huge objects.

Gravitational lensing can be simply refered to as a phenomenon where a gravitational field is created by a huge matter (cluster of galaxies) in space which distort and magnifies the lights coming from another huge matter (cluster of galaxies) from a distance but on thesame line of sight. (causing a formation of arcs of light around the huge object).

Answer 2

Arcs of light are created by gravitational lenses.

We can arrive at this answer because:

• Gravitational lenses are created by very large celestial bodies such as planets and galaxies.

• These gravitational lenses are created by the gravitational field of these bodies, which when emitting or reflecting light, create an illuminated line around it, forming arcs of light.

In summary, we can say that these arcs of light are formed when light from celestial bodies bends by following the magnetic field of very large celestial bodies.
