This synthetic image visualizes what a Roman ultra-deep field could look like. The resulting image helped us see more than 13 billion years back in time. The Hubble team harnessed the power of a long exposure time – hundreds of hours between 20 – which allowed the telescope to collect more light than it could in a single, short observation. “Our study helps demonstrate what a Roman ultra-deep field could tell us about the universe, while providing a tool for the scientific community to extract the most value from such a program.”īy capturing the Hubble Ultra Deep Field image, astronomers pulled aside the cosmic curtains to reveal that a tiny, seemingly empty slice of the sky was actually teeming with thousands of galaxies, each containing billions of stars. “Roman has the unique ability to image very large areas of the sky, which allows us to see the environments around galaxies in the early universe,” said Nicole Drakos, a postdoctoral scholar at the University of California Santa Cruz, who led the study. This Hubble observation transformed our view of the early universe, revealing galaxies that formed just a few hundred million years after the big bang.

The Roman Space Telescope is a NASA observatory designed to unravel the secrets of dark energy and dark matter, search for and image exoplanets, and explore many topics in infrared astrophysics.
