Astronomers have used all sorts of tricks over the years to try to convey the mind-boggling scale of the universe to us ordinary folks. If you could drive your car from here to the nearest star at 60 ...

The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us. This marks the edge ...

The universe's expansion means its size is bigger than its age suggests. The universe's expansion doesn't have a speed limit like objects within it. Distant galaxies move away from us as space itself ...

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an ...

The universe is truly magical: vast, mysterious, and endlessly fascinating. There’s something almost unreal about being able ...

Researchers led by the University of Tsukuba present computer simulations that capture the complex dynamics of elusive neutrinos left over from the Big Bang Current simulations of cosmic structure ...

Mikhail Ivanov, Oliver Philcox, and Marko Simonović won the New Horizons Award for their work on large scale structures — the strands and filaments of our universe which contain buried clues to its ...

TACC's Frontera supercomputer helped astronomers develop PRIYA, the largest suite of hydrodynamic simulations yet made of large-scale structures in the universe. Example Lyman-α forest spectra from ...
