There are so much particles in space that we don't really know everything that is out there. Recently, a signal has been detected in the space above the North Pole and scientists are trying to figure it out what it could be.
Though it's not clear exactly what's causing it, new research supports the idea that the signal may be coming from tiny, ultrafast-spinning grains of cosmic dust.
The strange North Pole signal, detected by a massive, all-sky survey, originates in some of the dustier corners of our galaxy and is part of a galaxy-wide signal that has puzzled scientists for decades.
Because this mysterious emission can muddy signals coming from the faint afterglow from the Big Bang, understanding it better could ultimately help researchers get a better picture of the early universe.
