Simulated Roman and Rubin Side-by-Side Comparison Images (IMAGE)
Caption
This pair of images showcases the same region of sky as simulated by the Vera C. Rubin Observatory (left, processed by the Legacy Survey of Space and Time Dark Energy Science Collaboration) and NASA’s Nancy Grace Roman Space Telescope (right, processed by the Roman High-Latitude Imaging Survey Project Infrastructure Team). Roman will capture deeper and sharper images from space, while Rubin will observe a broader region of the sky from the ground. Because it has to peer through Earth’s atmosphere, Rubin’s images won’t always be sharp enough to distinguish multiple, close sources as separate objects. They’ll appear to blur together, which limits the science researchers can do using the images. But by comparing Rubin and Roman images of the same patch of sky, scientists can explore how to “deblend” objects and implement the adjustments across Rubin’s broader observations.
A pair of images of space. The one at left is labeled "Vera C. Rubin Observatory, simulated image" and is a black background speckled with hundreds of warm-toned fuzzy blobs and smaller yellow, red, and orange dots. The image at right is the same, except it's labeled "Nancy Grace Roman Space Telescope, simulated image," and it's much sharper and clearer. The dots and blobs are less fuzzy, and also more white-toned with hints of yellow and green in some objects.
