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 ...

So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and helium, and fluctuations of energy and matter set into motion the formation of ...

(via Sabine Hossenfelder) In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot ...

(via Dr. Becky) There's a strange, unexplained feature of the Cosmic Microwave Background which seems to be aligned with the Solar System, and we don't why. Is it real or just a coincidence? And if it ...

The night sky deceives us. The universe should be ablaze with starlight, yet it isn’t. Discover how the finite speed of light, cosmic expansion, and invisible radiation from the Big Bang—the Cosmic ...

Full-Sky Map Of Cosmic Background Radiation, A Full-Sky Map Produced By The Wilkinson Microwave Anisotropy Probe (Wmap) Showing Cosmic Background Radiation, A Very Uniform Glow Of Microwaves Emitted ...

With CMB-S4, scientists hope to connect a sandy desert with a polar desert—and revolutionize our understanding of the early universe. In the 1960s, an anomalous, faint electromagnetic glow was ...

Nearly 400,000 years after the Big Bang, the primordial plasma of the infant universe cooled enough for the first atoms to coalesce, making space for the embedded radiation to soar free. That ...

The events surrounding the Big Bang were so cataclysmic that they left an indelible imprint on the fabric of the cosmos. We can detect these scars today by observing the oldest light in the universe.
