Add Yahoo as a preferred source to see more of our stories on Google. A new simulation released by NASA’s Ames Research Institute reveals a stunning vision of the evolution of a galaxy. Blue influx ...

In collaboration with the US' Georgia Institute of Technology, researchers from Maynooth University in Ireland have unveiled a new computer simulation that mirrors early universe conditions, ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

In a feat of galactic archeology, astronomers are using ever more detailed information to trace the origin of our galaxy—and to learn about how other galaxies formed in the early stages of the ...

"To make progress towards a theory of galaxy formation, it is crucial to compare results and codes from different simulations. We have now done this by bringing together competing code groups behind ...

An international research team has used the James Webb Space Telescope and the Atacama Large Millimeter/submillimeter Array to observe the most distant galaxy protocluster to date, 13.14 billion light ...

Ultramassive black holes (UMBHs), observed to be tens of billions of times the Sun's mass, pose a theoretical challenge regarding their rapid formation early in the universe. A proposed hypothesis, ...

A new study of diffuse dwarf galaxies is challenging the prevailing galaxy formation model within the standard Cold Dark Matter (CDM) framework, leading to a proposed new model of dark matter. Under ...

When scientists viewed the James Webb Space Telescope’s (JWST) first images of the universe’s earliest galaxies, they were shocked. The young galaxies appeared too bright, too massive and too mature ...
