ESA

Galileo's highly-accurate clocks are at the heart of the system. Each satellite emits a signal containing the time it was transmitted and the satellite's orbital position. Because the speed of light is known, the time it takes for the signal to reach a ground-based receiver can be used to calculate the distance from the satellite.

Kirchhoff, Gustav (1824

Using the spectroscope, Kirchhoff showed that each element, when heated to incandescence, produced a characteristic pattern of emission lines. This led to the identification of cesium in 1860 (named in Latin for the sky blue color of its emission lines), and rubidium in 1861

Flame Test

The green color denotes the presence of the element boron (B) which you'd expect in boric acid. The cream of tartar yielded a purple-colored flame. Purple is associated with the presence of potassium (K). That's because cream of tartar is a potassium salt. These element-specific colors are catalogued in an emission spectrum.
