BICEP (Background Imaging of Cosmic Extragalactic Polarization) and the Keck Array are a series of cosmic microwave background (CMB) experiments.

And those fluctuations were stretched to astronomical sizes, and those fluctuations eventually are the things we see in the cosmic microwave background.

This is the noise that Penzias and Wilson heard the oldest sound that you're ever going to hear, the cosmic microwave background radiation

These predictions are in excellent agreement with observations by the WMAP satellite of the cosmic microwave background, which is an imprint of the very early universe.

The best evidence for dark matter today comes from measurements of something called the cosmic microwave background, the afterglow of the Big Bang, but that's another story.

This is the WMAP microwave background that we see.

This is the noise that Penzias and Wilson heard the oldest sound that you're ever going to hear, the cosmic microwave background radiation left over from the Big Bang.

So, that's why we study things like dark matter, black holes, dark energy, and we also look at remnants of the early universe, the cosmic microwave background that satellites.

It was big enough to be transparent to light, and that's what we see in the cosmic microwave background that George Smoot described as looking at the face of God.

In 1989 NASA launched the Cosmic Background Explorer satellite (COBE).

Based on measurements of the expansion using Type Ia supernovae, measurements of temperature fluctuations in the cosmic microwave background, and measurements of the correlation function of galaxies, the universe has an estimated age of 13.798 0.037 billion years.

For example, the cosmic microwave background radiation that we see right now was emitted at the time of photon decoupling, estimated to have occurred about 380,000 years after the Big Bang, which occurred around 13.8 billion years ago.

Subsequently many other observations have indicated the presence of dark matter in the universe, including gravitational lensing of background objects by galaxy clusters such as the Bullet Cluster, the temperature distribution of hot gas in galaxies and clusters of galaxies and, more recently, the pattern of anisotropies in the cosmic microwave background.

Neutrino detectors are often built underground to isolate the detector from cosmic rays and other background radiation.

The concept of the big bang can be traced back to the discovery of the microwave background radiation in 1965.

But what they're seeing, way out there in the far reaches of the microwave background, is this kind of odd undulation.

Terrestrial microwave

Particle beams accelerated at the Sun are superimposed on the uniform and isotropic cosmic ray background from galactic and extragalactic sources.

We've shown that it can fit all of the data that we have about the formation of galaxies, the fluctuations in the microwave background.

The exposures due to cosmic rays, terrestrial gamma rays and ingestion vary only slightly with time, so they can be regarded as the basic background exposure to natural sources.
