13. Planets by the thousands—exoplanets & the coronagraph

This near-IR, ground-based image from the Keck Telescope was created using a coronagraph to block out the young star at the center. Even with some stray starlight entering the telescope, researchers were able detect four Jupiter-mass objects orbiting around the young star.

This image was taken from the ground. Roman will be observing from above Earth’s atmosphere, where it will have a much sharper view. In addition, Roman’s “inner working angle” will be smaller than current ground-based telescopes—i.e., we can image closer to the star itself to look for planets that are orbiting more closely to its host star.

20. Roman Science—Galaxies by the millions—nearby galaxies

The slide image features galaxy UGC 2885 (nicknamed Rubin's Galaxy after astronomer Vera Rubin). Hubble's view is inset, and the Roman field of view is shown with the grid of squares. Roman will capture the entire halo of galaxies like Rubin in a single pointing; the size of the galaxy’s halo is estimated and shown here as the purple circle.

28. Roman’s efficiency—more of the sky in less time

This simulated image illustrates the wide range of science enabled by Roman's extremely wide field of view and exquisite resolution. The yellow squares—which all contain background imagery simulated using data from Hubble’s Cosmic Assembly Near-infrared Deep Extragalactic Survey (CANDELS) program—outline the area Roman can capture in a single observation. A blue square shows the field of view of Hubble’s Wide Field Camera 3 for comparison.
