Gravitational-Lens Gallery Supports Complementary Telescope Research

In this lesson: Separate an observed lensing effect from a proposed theoretical test.

Read the story

NASA released a Hubble lens gallery on November 12. Foreground galaxies bend and magnify light from more distant galaxies, producing distorted arcs.

Hubble’s detailed imaging complements Roman’s wider field. Researchers intend to model the distortions to investigate mass distributions, rather than treat the gallery as proof of a particular dark-matter theory.

Read and practise

1. Where does the light that is magnified come from?

   1. Only the foreground galaxies
   2. The Roman telescope itself
   3. The more distant galaxies

2. What is the status of the dark-matter work described?

   1. A claim that no mass can be studied
   2. An intended investigation using models
   3. A specific theory already proved by this gallery

Your turn

Explain the observation, the planned analysis and the limit on the conclusion.
