A team of cosmologists from the University of Paris-Saclay, CNRS/IN2P3, Jagiellonian University and the University of Geneva derived a general expression for the bispectrum in bouncing cosmologies and then compared the results ...
The James Webb Space Telescope has helped astronomers detect the first chemical signs of supermassive stars, "celestial monsters" blazing with the brightness of millions of Suns in the early universe.

Astrophysicists have been trying to understand the formation of cosmological objects and phenomena in the universe for decades. Past theoretical studies suggest that quantum fluctuations in the early universe, known as primordial ...
An international team of space scientists has found evidence suggesting that planets could have formed during the so-called "cosmic noon." In their study, reported in the journal Nature Astronomy, the group used data from ...
Primordial holes formed in the exotic conditions of the big bang may have become their own source of matter and radiation.
