The full UV-visible-IR composite of the XDF; the greatest image ever released of the distant Universe.
In a region just 1/32,000,000th of the sky, we’ve found 5,500 identifiable galaxies, all owing to the Hubble Space Telescope.
Hundreds of the most distant ones seen here are already unreachable, even at the speed of light, due to the relentless expansion of space.
A galaxy will typically contain few billion to several trillion stars.
