A cloud of gas expelled by a dying star has done something rare in nature: it cooled below the background temperature of deep ...

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.

One of the Holy Grails in cosmology is a look back at the earliest epochs of cosmic history. Unfortunately, the universe's first few hundred thousand years are shrouded in an impenetrable fog. So far, ...

A proposed cosmology model argues that the universe may contain ordinary matter alone, without dark matter or dark energy.

The cosmic microwave background (CMB) is the relic radiation from the early Universe, imprinted at the epoch of recombination when photons decoupled from matter. Detailed measurements of its ...

As it studies cosmic microwaves, the Simons Observatory in Chile aims to help prove or disprove cosmic inflation, a notion that the universe expanded rapidly in the moment after the Big Bang. Two of ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

The cosmic microwave background (CMB) provides a snapshot of the primordial Universe, with tiny temperature fluctuations (anisotropies) encoding the seeds of large-scale structure. These fluctuations ...

A MYSTERIOUS pattern seen in the cosmic microwave background – the faint afterglow of the big bang – has left some physicists wondering whether this central plank in the evidence for the big bang is ...
