There are certainly some extremely bright stars and planets in the vastness of space. But many of us expect most of space to be extremely dark with nothing but pitch black darkness. However, a new study to be published soon has found that outer space isn’t pitch dark after all. According to the study, the outdoor space is filled with light.
Researchers at the National Optical Astronomy Observatory in Arizona studied light in deep space using NASA’s New Horizons mission. New Horizons’ main mission was to study Pluto, and after spending six months doing so, he headed into deep space. Currently, New Horizons is more than 4 billion miles from home.
While the universe is filled with stars, New Horizons is far enough away in deep space that it would presumably have a good look at pitch-black darkness. The researchers studied what were expected to be the hollowest photographs of deep space taken by the spacecraft, particularly those with no bright objects inside them. The images were processed to remove all light from known sources, including any relatively nearby stars.
The team also removed more light from galaxies that are believed to exist but have not been found. Scientists are left with deep space images without any light pollution. Interestingly, despite the removal of all known light from known and unknown sources, there was still a lot of light in the images. Where exactly the remaining light comes from is a mystery.
Theories suggest that the light could come from undiscovered stars or galaxies. However, light could be something completely new. More research will undoubtedly be conducted as scientists try to find out where exactly all the extra light is coming from. For now, the source will remain a mystery.
