Glossary term: Black Body Radiation

Description: Black body radiation is electromagnetic radiation from an idealized object (black body) that absorbs all radiation that falls on it and re-emits it at a rate that maintains a state of thermal equilibrium. The spectrum of black body radiation is completely specified by the body's temperature according to known laws. Stars emit light similar to that of a black body at a temperature of several thousand degrees kelvin. To be contrasted with synchrotron radiation and other forms of "non-thermal" radiation.
