In 2003, the Hubble Space Telescope pointed at a dark, empty patch of sky.
It watched this spot for 270 hours, patiently collecting light…
and found the most distant galaxies known.
10,000 galaxies in one tiny patch of sky.
Forever changing our understanding of how truly vast the universe is,
and how many galaxies are out there.
The Nancy Grace Roman Space Telescope could do the same thing…
on a much larger scale.
There is no telling what we might learn.
