About Hubble distance
The map lists it as a region / boundary (horizon) and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.
c/H0 = 14.45 billion light-years (4.43 Gpc): the distance at which galaxies recede at the speed of light today. Galaxies beyond it are still visible because the expansion rate has changed over time.
Key numbers
| Distance (comoving, today) | 14.5 billion light-years (4,431 Mpc) |
|---|---|
| Redshift z | 1.476 |
| Light travel time | 9.457 billion years |
Where it is
Its place in the universe, from the inside out: Observable universe.

From Wikipedia
Hubble's law, officially the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. Thus, the farther a galaxy is from the Earth, the faster it moves away.
