Designed to study Pluto, the spacecraft’s instruments are being repurposed. //

New Horizons is now nearly twice as far from the Sun as Pluto, the outer planets are receding fast, and interstellar space is illuminated by the vast swath of the Milky Way ahead. But the spacecraft’s research is far from over. Its instruments are all functioning and responsive, and the New Horizons team has been working hard, pushing the spacecraft’s capabilities to carry out new tasks. //

In 2021, his team photographed a dark patch of sky and digitally removed all known light sources in the Universe. What remained—the estimated COB—is roughly twice as bright as expected. “Our test field was far from the Milky Way, bright stars, dust clouds—anything that would wash out the fragile darkness of the Universe, yet that mysterious glow is still there. It’s like being in an empty house out in the countryside, on a clear moonless night, with all the lights turned off, and finding it’s not completely dark,” said Lauer.
