Industry:Aerospace
An ideal or imaginary body that is absolutely black when cold, but is a perfect absorber of radiation and at the same time a perfect radiator. Black body temperatures are used to work out the theoretical laws of radiation and to calculate the temperature of the sun.
Industry:Astronomy
The amount of matter in a body, which should not be confused with weight. The same object will have different weights in space and earth but the mass remains constant.
Industry:Astronomy
The emission of electromagnetic radiation as the result of exposure to some other radiation, which emission ceases when the stimulus that produces it ceases to act on the emitting substance. Thus light passing through a gas, may change the energy state of the atoms and cause them to emit light of a different wavelength.
Industry:Astronomy
The s. I. Unit of energy, work, or quantity of heat. It is the force of one newton acting over a distance of a meter.
Industry:Astronomy
A gas used by all green plants and recycled by them to form wood and the oxygen we breathe. In very large quantities it can be poisonous to animal life.
