This animation shows a simulation of the type of science that astronomers will be able to do with future deep field observations from NASA’s Nancy Grace Roman Space Telescope. The gravity of intervening galaxy clusters and dark matter can lens the light from farther objects, warping their appearance as shown in the animation. By studying the distorted light, astronomers can study elusive dark matter, which can only be measured indirectly through its gravitational effects on visible matter.
Some teams will explore how they might combine data from different observatories and use multiple telescopes in tandem. For example, using PRIME and Roman together would help astronomers learn more about objects found via. And Roman scientists will be able to lean on archived Hubble data to look back in time and see where cosmic objects were and how they were behaving, building a more complete history of the objects astronomers will use Roman to study.
