Let’s Begin…
Our best technology can send men to the Moon and probes to the edge of our solar system, but these distances are vanishingly small compared to the size of the universe. How then can we learn about the galaxies beyond our own? Yuan-Sen Ting takes us into deep space to show how astronomers study the stars beyond our reach.

Read how rainbows can be used to study the composition of stars, and to obtain the temperature of stars. Plasma in hotter stars moves more vigorously. This vigorous movement broadens the features in spectra due to the Doppler Effect. Visit the Center for Astrophysics | Harvard & Smithsonian for more information!
