In one sentence: Researchers at Pacific Northwest National Laboratory found that when miniscule particles of airborne dust, thought to be a perfect landing site for water vapor, are modified by pollution, they change cloud properties via ice crystal number concentration and ice water content.

A team of scientists led by Pacific Northwest National Laboratory atmospheric researcher Dr. Susannah Burrows and collaborator Daniel McCoy, who studies clouds and climate at the University of Washington, reveal how tiny natural particles given off by marine organisms — airborne droplets and solid particles called aerosols — nearly double cloud droplet numbers in the summer, which boosts the amount of sunlight reflected back to space.

A number of similar black hole exploration methods have also been proposed in optical / infrared spectra so far, but one crucial problem is that emissions at these wavelengths are absorbed by interstellar dust particles although the more active black holes contain more dust particles.
