New Horizons Unveils Universe's Profound Darkness

NASA's spacecraft provides the most precise measurements of cosmic light, confirming galaxies as the primary source.

New Horizons, now 5.4 billion miles from Earth, offers a unique vantage point for measuring cosmic light.
Findings indicate the universe's visible light is almost entirely generated by galaxies.
The spacecraft's measurements resolve long-standing uncertainties caused by interplanetary dust and sunlight.
This research supports the current understanding of the universe's structure and distribution of galaxies.
Published in The Astrophysical Journal, the study marks a significant contribution to cosmology.
