Grammar in this story: Complementary strengths
complements
Complements means adds a different useful capability: Hubble’s detail works alongside Roman’s wider field.
Your turn
Explain the observation, the planned analysis and the limit on the conclusion.
See one possible answer
Foreground galaxies distort and magnify background light into arcs. Researchers intend to model these distortions to investigate mass distributions with complementary telescope views. The gallery itself is not proof of a particular dark-matter theory.
