The Sun Bakes Wildfire Smoke, Changing Its Toxicity

by Jackie Rocheleau 13 June 202213 June 2022

A new study questions the narrative that dilution is the solution to pollution.

The Sun, a round orange orb, is observed through an ultraviolet filter that gives its surface a mottled deep orange look. There are a few prominences along the edge of the circular disk and one loop at around one o’clock, but there are no sunspots visible on the surface.
