The cosmic microwave background radiation
Reviews of Modern Physics, 1979Radio Astronomy has added greatly to our understanding of the structure and dynamics of the universe. The cosmic microwave background radiation, considered a relic of the explosion at the beginning of the universe some 18 billion years ago, is one of the most powerful aids in determining these features of the universe. This paper is about the discovery

, 2002 The planet Earth orbits the Sun in what is often considered to be empty space but is in fact full of very small charged particles speeding in all directions. The situation can be compared to the Earth having to constantly travel in a light shower of rain and with the atmosphere acting like an umbrella. The 'rain' is made up of charged particles called '

American Journal of Physics, 1960
The paper gives some general information about cosmic rays, especially with regard to the properties of the primary flux: charge composition, energy spectrum, and time variations. The experimental evidence for these properties of the cosmic rays is outlined briefly and possible origins of the radiation are discussed.

Anisotropy of the Cosmic Blackbody Radiation
Science, 1986The universe is filled with thermal radiation having a current temperature of 2.75 K. Originating in the very early universe, this radiation furnishes strong evidence that the Big Bang cosmology best describes our expanding universe from an incredibly hot, compacted early stage until now.
