Hubble and Roman Bring Different Strengths to Galaxy Images

In this lesson: Connect distorted light with complementary research roles.

Name: __________________________ Date: __________________

Read the story

NASA’s new Hubble gallery shows distant galaxies distorted by the gravity of nearer galaxies. The bent light can form arcs.

Hubble provides detailed individual views, while Roman covers a wider field. Researchers plan to combine their observations to study mass, including dark matter.

Read and practise

1. Which galaxies provide the bending gravity?

   1. Nearer galaxies
   2. Only the distant background galaxies
   3. The telescope’s own gravity

2. Why combine the observations?

   1. To show both telescopes have identical fields
   2. To remove all distortion before studying it
   3. To study mass using detailed and wider views

Your turn

Describe the cause of the arcs and the planned benefit of combining observations.
