Chances are your room is about as dusty as space is. That obnoxious, intimidating layer of dust that coats your home before you begin spring cleaning is similar to the dust that surrounds local stars and planets that astronomers are attempting to study. Scientists have located nine stars that may be surrounded by habitable planets, but the space particles are blocking light crucial for the further investigation of those regions.
This same dust-related glare is known in our solar system as zodiacal light. What essentially happens when we observe zodiacal light is that light is being diffused from billions of tiny particles stretching all the way from Mercury out as far as Mars.
