There is an infrared vision headpiece being manufactured now for use by
firefighters that will see through smoke effectively. Also that capability
of longer wavelengths to zip through fine particles is being exploited by
infrared astronomers to peer into dusty nebulae to see star formation and
into the galactic core to see the black hole monster residing there.
