The power spectrum measured by Planck, showing the fluctuations in temperature at a range of size scales on the sky. The anomaly previously seen by WMAP lies at the left edge. The three major peaks show the relative contributions of dark energy, ordinary matter, and dark matter. ESA/Planck Collaboration/D. Ducros

Study of the Cosmos, at best, is considered a semi-scientific discipline, primarily because the laboratory for carrying out measurements and tests of theories (the Cosmos) has been largely inaccessible for centuries. The cosmic vista into the yonder, however, continued to fascinate humankind due to its inherent beauty and sheer curiosity. The inven...

... initial ultra- violet photons resulting from recombination, however, converted to the microwave spectral region as the un- iverse cooled further down to its current level. The power spectrum of the fluctuations over the sky, revealed by Figure 7, yields crucial information on the structure and composition of the Universe. The most prominent fluctuations are due to the total energy content of the Universe, while the smaller ones are associated with the distribution of matter alone, both ordinary and dark. ...
