For nearly three decades, astronomers have interpreted the faint luminosity of certain distant explosive stars as a sign of ...

For almost a century, we have known that the universe is expanding. For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates were the ...

The universe's first galaxies were hot messes, according to a recent study. During their younger days, they were wild, ...

By observing the brightness of distant dying stars, astronomers have long come to believe that the expansion of the universe ...

Led by doctoral student Tatsuya Kotani and Professor Tomoharu Oka from Keio University, the research team measured the ...

Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they ...

Everything we know about the evolution of the early universe is currently being challenged. Multiple galaxies discovered by the James Webb Space Telescope do not match up with the standard model of ...

Newly formed dwarf galaxies were likely the reason that the universe heated up about 13 billion years ago, according to new work by an international team of scientists. The finding opens an avenue for ...

In this Chigago Tonight video, Katrin Heitmann from Argonne National Lab describes one of the most complex simulations of the evolution of the universe ever created. “First of all, what we want to ...

When I thought about evolution, I always pictured big changes that happened over long time periods – like how birds evolved from dinosaurs. But then I talked with my friend Jeremiah Busch. He’s a ...

A new simulation showing the evolution of the universe traces the formation of the cosmic web of galaxies scientists see today. The simulation - called Illustris - covers about 13 billion years of the ...
