A University of Missouri astronomer, Haojing Yan, leads a global team of 130 researchers from 62 institutions to conduct the Roman eXtreme Deep Field (RXDF) project, using NASA's Nancy Grace Roman Space Telescope to capture an unprecedented view of the early universe.

The RXDF aims to determine whether unusual early-universe observations seen by Webb are anomalies or part of a broader cosmic pattern by surveying a vast area of the distant universe at unprecedented depth and scale.

The mission underscores a broader goal of paving the way for future observatories and expanding humanity’s understanding of our place in the cosmos.

Yan notes that deep-field campaigns often yield revolutionary discoveries beyond the original goals, highlighting the potential for unexpected findings in the RXDF data.

The project seeks to understand how the earliest galaxies formed stars and assembled into larger structures, investigate the origins and rapid growth of supermassive black holes, and identify mysterious objects known as little red dots to determine their nature.

The Roman Space Telescope will provide a wide field of view with a 300-megapixel infrared camera (Wide Field Instrument), allowing a single image to cover areas that would require hundreds of Webb or Hubble observations, enabling broader patterns to be studied at depth.

NASA has allocated 386 hours of observation time for the RXDF program, enabling deep-field observations aimed at studying thousands of early galaxies, exploding stars, giant black holes, and other cosmic phenomena from the universe’s first 100 million years.
