sand radiates infrared

    Heating a Greenhouse by Ron Kurtus - Physics Lessons , sand radiates infrared ,The glass then re-radiates the infrared back to the material inside the greenhouse, thus trapping the thermal energy inside the building and keeping it at a warmer temperature , Since heated materials give off infrared radiation, the warm greenhouse soil, water, sand and other materials emanate this thermal radiation in longer ,Black Hole Moon - xkcdA black hole the mass of the Moon would have an event horizon about the size of a sand grain Specifically, according to one of my favorite charts, a black hole moon would be a grain of fine to medium-fine sand, and could pass through a sieve of size ASTM No 70 or larger I mean,then radiates that heat as infrared light.
