Envisioning an Ultra Deep Field from NASAs Roman Space Telescope
A team of astrophysicists has created a simulated image that shows how the Nancy Grace Roman Space Telescope could conduct a megaexposure similar to but far larger than Hubbles celebrated UltraDeep Field Image. This Hubble observation transformed our view of the early universe, revealing galaxies that formed just a few hundred million years after the big bang. By capturing the Hubble UltraDeep 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. The Hubble team harnessed the power of a longexposure time hundreds of hours between 2002 and 2012 which allowed the telescope to collect more light than it could in a single, short observation. The resulting image helped us see more than 13 billion years back in time. Hubbles UltraDeep Field Image offers an incredible window to the early universe, but an extremely narrow one, covering less than one ten million
