That cosmologists cannot agree on one of the most elementary facts about the universe is striking enough. But that ...

Amid simmering anxiety about the future of federally funded science, the U.S. government has quietly withdrawn support for ...

Recent studies indicate that the universe may be decaying or expanding more rapidly than expected, raising questions about ...

The cosmic microwave background (CMB) radiation originated about 300,000 years after the Big Bang. The CMB's light, initially near-infrared, is now microwave radiation due to the universe's ...

The CMB tells us lots of important information about what the universe was like long ago. According to the Big Bang theory, the early universe was very hot and full of radiation.

To see the effects of the gravity generated by dark matter throughout the universe, cosmologists turned to another elusive area of interest— cosmic microwave background radiation (CMB).

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 light — ...

Cosmology is currently in a crisis known as the Hubble tension: the local universe appears to be expanding about 10% faster than expected. The predicted rate comes from extrapolating observations of ...

This telescope was able to map out cosmic microwave background (CMB) radiation. This radiation presents itself as heat left over from the Big Bang almost 14 billion years ago.

Discrepancies exist between the Hubble constant values derived from cosmic microwave background (CMB) radiation measurements (approximately 68 km/s/mpc) and those from supernova observations ...
