The first ever space telescope, the Orbiting Astronomical Observatory 2 (OAO-2), was launched into the low Earth orbit in ...

Besides enabling it to map 75% of the night sky, the telescope's unprecedented sensitivity lets it receive microwave signals from the cosmic dawn, or the first billion years of the universe's life.

New images from the now-decommissioned Atacama Cosmology Telescope (ACT) provide the most precise glimpse yet of the universe just 380,000 years after the Big Bang. These images of the cosmic ...

The Cosmic Microwave Background (CMB) is the first light that was able to freely move across the Universe. Released around 400,000 years after the Big Bang, it is a map that has been used by ...

Scrutinizing the cosmic microwave background has enabled scientists to search for exotic particles too light to be found any other way. Image Credit: Planck Collaboration/European Space Agency ...

Various large-scale astrophysical research projects are set to take place over the next decade, several of which are so-called cosmic microwave background (CMB) experiments. These are large-scale ...

While the cosmic-ray population at EeV energies may include contributions from extra-galactic cosmic rays, and the end of the spectrum may be determined by collisions with relic ...

The cosmic microwave background (CMB) was generated when our universe was only 380,000 years old. At the time, our cosmos was about a million times smaller than it is today and had a temperature ...

A major project to study leftover radiation from the early universe using ultra-sensitive telescopes at the South Pole and Chile will not progress to the design stage “in its current form,” the ...
