"We really needed the sensitivity of JWST. We also needed the 100 times magnification from gravitational lensing from a ...

New multiscale simulations help crack long-standing mysteries behind the enormous radio arcs generated when galaxy clusters ...

Galaxy clusters are the largest gravitationally bound structures in the universe, with each containing hundreds or even ...

Although these findings from JWST are yet to be confirmed, they mark the closest astronomers have come to locating the ...

An international team led by ICREA researcher Mark Gieles, from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), has ...

A new model sheds light on the long-standing chemical mysteries found in globular clusters, the ancient archives of the universe. An international collaboration led by ICREA researcher Mark Gieles, fr ...

Scientists led by a team from the University of Chicago recently released a study that mapped some of the largest known objects in the universe. The study may help scientists test theories about how ...

A new study finds that galaxy clusters — cosmic cities packed with thousands of galaxies — trace invisible highways of dark matter stretching up to a billion light years across the universe. Even more ...

The first stars in the Universe were born several hundred million years after the Big Bang, ending a period known as the cosmological ‘dark ages’ when atoms of hydrogen and helium had formed, but ...

Scientists have released a new study that catalogues the universe by mapping huge clusters of galaxies. These clusters are some of the largest known objects in the universe — and they can help ...

New simulations reveal how galaxy cluster collisions create ghostly radio relics. Turbulence and shock compression amplify ...

New model shows extremely massive stars, over 1,000 solar masses, shaped the birth and early evolution of the universe's oldest star clusters. (Nanowerk News) An international team led by ICREA ...
