Astronomers discovered cosmic microwave background radiation in the 1960s. The wavelength of this radiation appears to be the same no matter where in space that it comes from and it corresponds to ...

This Cosmic Microwave Background Radiation (CMBR) is the conclusive evidence ... If the universe had no boundary and no origin, it would be static with an infinite number of stars.

The cosmic microwave background (CMB, CMBR), in Big Bang cosmology, is electromagnetic radiation which is a remnant from an early stage of the universe, also known as "relic radiation". The CMB is ...

Most cosmic rays are deflected or neutralized by Earth’s atmosphere and magnetic fields. Some do reach the ground, but they’re generally no worse than any other background radiation we are routinely ...

These jets become elusive the farther back in time astronomers try to look because of the so-called cosmic microwave ...

114, No. 791 (January 2002), pp. 83-97 (15 pages) ABSTRACT Design and performance details are given for the Cosmic Background Imager (CBI), an interferometer array that is measuring the power spectrum ...

One of the best ways to observe this era is with low-frequency radio telescopes, which can observe the “spin-flip” radiation from the hydrogen that pervades the Universe during the Cosmic Dawn.

The radiation we receive from outer space is called cosmic radiation or cosmic rays ... With all the knowledge so far collected on effects of radiation, there is still no definite conclusion as to ...
