The discovery of the universe’s oldest stars, identified within our own Milky Way galaxy, marks a significant leap forward in our understanding of cosmic history. These ancient stars, formed shortly ...

A systematic search for the first bright galaxies to form in the early universe has revealed a dramatic jump in the number of such galaxies around 13 billion years ago. These observations of the ...

About 13.8 billion years ago, within a millionth of a second after the Big Bang, the universe existed in an ultra-hot and dense state. Instead of protons and neutrons, the fundamental building blocks ...

A small group of young researchers at the Cosmic Dawn Center, Niels Bohr Institute, University of Copenhagen, have, through observations of the early stages of an extremely large galaxy cluster's ...

A new study led by University of Minnesota astrophysicists shows that high-energy light from small galaxies may have played a key role in the early evolution of the Universe. The research gives ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

The plot represents the new model with the x-axis and the y-axis showing the minimum sizes of collapsing and expanding regions that can impact cosmological measurements. The contours are independent ...
