Southwest already serves more domestic passengers than any other airline, but near-international markets like Latin America and the Caribbean represent a big potential growth opportunity for the company. Southwest Airlines is breaking ground on a new international terminal in Houston.The Houston terminal is a big part of Southwest's international expansion plans. Houston is the fifth-largest U.S. metropolitan area, so it has plenty of local traffic, and it is well located to serve as a Latin American gateway.outhwest already serves more domestic passengers than any other airline, but near-international markets like Latin America and the Caribbean represent a big potential growth opportunity for the company.

The unit of measuring the brightness-or to use the precise scientific terminology, illuminance-in SI system of measurement is lux or lumen per square meter.Illuminance is measured in foot candles. One foot-candle is equal to 10.76 lux. Please note that lumen is the measure of total light emitted by a source of light.he total amount of visible light is measured in units of lumens. How bright it appears when it falls on a surface area is illuminance. When the same luminous flux falls over a larger area it will appear to be less bright. 1 lx = 1 lm/m^2 which in terms of the basic SI units is 1 cd*sr*m^-2.
However, the brightness of a star depends on its composition and how far it is from the planet. Astronomers define star brightness in terms of apparent magnitude (how bright the star appears from Earth) and absolute magnitude (how bright the star appears at a standard distance of 32.6 light years, or 10 parsecs).
