(CNN) - Scientists have officially discovered a new smell.
Researchers are calling the smell "olfactory white," meaning the scent has parallels with both white light and white noise.
It is made up of more than 40 different smelly compounds.
While discovering the smell, scientists found that scents with more components are harder to tell apart because they all smell alike.
For now, you can only take a whiff of "olfactory white" in a laboratory.
