Elliptical galaxies are some of the oldest types of galaxies in the universe. They formed relatively quickly after the Big ...

Known today as the Cosmic Microwave Background, it’s alternatively been called the “primeval fireball” or the Big Bang’s leftover glow. It was an astonishing prediction dating back to ...

The Cosmic Microwave Background, or CMB, is radiation that fills the universe and can be detected in every direction. Microwaves are invisible to the naked eye so they cannot be seen without ...

The primordial cosmic microwave background (CMB) radiation has since traveled some 13.8 billion years through the expanding cosmos to our telescopes on Earth and above it. But the CMB isn’t just ...

The radiation became known as the cosmic microwave background (CMB). It was extraordinarily uniform across the sky and showed that the universe at that young age was smooth, without the clumps of ...

Until we can directly detect the signatures of what was released earlier -- the cosmic neutrino background, gravitational waves from inflation, etc. -- the CMB will be our window into the earliest ...

Cosmic microwave background is a sea of radiation that provides us with evidence for the big bang. When around 1916 Einstein first used general relativity to build a cosmic model, he followed the ...
