"New Horizons: Measuring the Universe's True Darkness from Afar"
The New Horizons spacecraft, currently twice as distant from the sun as Pluto, has measured the darkness of the universe by capturing images of a patch of sky far away from the Milky Way, the sun, and bright stars. Comparing the amount of light captured to Hubble's view of the dark sky, researchers found that it was darker by an expected amount, but there was still some unexplained faint glow. The team plans to observe 15 other dark locations to further investigate this mysterious background glow and potentially gain insight into the true darkness of the cosmos.
