Gravitational Lensing Observations Quiz: Test Your Astronomy

This assessment explores gravitational lensing, a phenomenon where massive objects like galaxies bend light from distant stars. It evaluates your understanding of key concepts such as the physics behind lensing, its observational...

Questions: 20 | Attempts: 12 | Last updated: Mar 13, 2026

Sample Question 1
When a quasar is strongly lensed into multiple images, the images can:

Always arrive at the same time

Vary in brightness at different times due to different travel times

Lose all colour information

Stop emitting light

Sample Question 2
Lensed images can show the same intrinsic variability (like quasar flickering) but shifted in time.

True

False

Sample Question 3
A key reason for time delays in lensing is:

The telescope clock runs slow

Light follows different paths and experiences different gravitational time effects

Light changes into sound

Stars change colour

Questions: 20 | Attempts: 10 | Last updated: Mar 13, 2026

Sample Question
Weak lensing is especially valuable because it can:

Measure sound speed

Map mass (including dark matter) over large areas

Change star colours

Stop galaxies from forming
