Much of our contemporary understanding of space systems dates back to Isaac Newton. It's surprising to think that the underpinnings of astronomy are centuries old. While for a time it seemed as though major discoveries in the field had stagnated, in the early twentieth century, scientists like Albert Einstein and Max Planck redefined our understanding of light waves. And in 1948 scientists developed a theory about how our entire universe came to be, a theory that would be proven in 1965. The Big Bang Theory and Light Spectra is modeled closely on Next Generation Science Standards. The book explains the science behind these groundbreaking discoveries, profiles the scientists responsible, and details the technology astronomers and astrophysicists use to continue refining our knowledge
