 Many satellite imagery providers (e.g. Planet 0.5m) include NIR bands. NIR puts particular emphasis on plants and vegetation, and can be used with other bands to detect regions of ice, vegetation, fires, etc. A common method of analysis is to simply use the imagery as you would optical, but replace the "red" band (e.g. in Qgis) with the NIR data.

 The remote sensor passively collects light in this range and forms an image exactly like how we are used to.
