Roman lensing blooms (IMAGE)
Caption
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. As a bonus, this lensing also makes it easier to see the most distant galaxies whose light they magnify. Simulations like this one help astronomers understand what Roman’s future observations could tell us about the universe, and provide useful data to validate data analysis techniques.
