Understanding Einstein Rings and Gravitational Lensing

What is an Einstein ring?

• A type of galaxy

• A feature of gravitational lensing

• A new planet

• A type of star

What is the molten ring?

• A small star cluster

• A type of black hole

• A new planet discovered by Hubble

• A large galaxy cluster forming a near-complete Einstein ring

How does Einstein's theory of general relativity relate to gravitational lensing?

• It describes the movement of planets

• It explains the formation of stars

• It predicts the bending of light by gravity

• It is unrelated to gravitational lensing

What effect does gravitational lensing have on the appearance of background galaxies?

• It stretches and magnifies them

• It makes them appear smaller

• It changes their color

• It makes them disappear

What role does the Hubble Space Telescope play in the study of Einstein rings?

• It creates Einstein rings

• It captures clear images of Einstein rings

• It distorts the images of galaxies

• It has no role in studying Einstein rings
