There are definitely some very bright stars and planets in the vastness of space. But many of us would expect most of the space to be very dark with nothing to see but complete darkness. However, a new study will be published soon and it has found that outer space is not black at all. According to the study, outer space is filled with light.
Researchers From the National Observatory of Optical Astronomy in Arizona, they studied light in deep space using the NASA New Horizons mission. The New Horizons’ main mission was to study Pluto, and after spending six months doing this, they headed to deep space. Currently, New Horizons is more than 4 billion miles from home.
As the universe fills up with stars, New Horizons is far enough into deep space that it would presumably have a good look at the pitch-black. Researchers studied what was expected to be the most emptying deep space images taken by the spacecraft, specifically those without bright objects in them. The images were processed to remove all the light from known sources, including any stars that are relatively close.
The team also removed more light from galaxies that were believed to exist but had not been found. Scientists have left the deep space photos without any light pollution. Interestingly, although all of the known light has been removed from known and unknown sources, there is still a lot of light in the photos where exactly the remaining light comes from is a mystery.
Theories suggest that the light could be from stars or galaxies that have yet to be discovered. However, light can be something completely new. No doubt more research will be done as scientists search for the exact source of all the extra light. For now, the source will remain a mystery.
