Study Identifies Systematic Instabilities in Quasar Dipole Measurements. New Analysis Challenges "Lopsided Universe" ...

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

For a generation, cosmologists have worked with a simple story: the universe is not only expanding, it is expanding faster and faster under the steady push of dark energy. A growing body of fresh data ...

Astronomers have stumbled onto a structure so vast and so oddly shaped that it threatens to upend one of cosmology’s most cherished assumptions about how the universe is built. The “Big Ring,” a ...

Our best models of the cosmos don't add up — but that could change if the universe is actually made of a viscous 'fluid,' a new paper suggests. When you purchase through links on our site, we may earn ...

There may not be as nearly as many small galaxies in the early universe as astronomers predict there should be, which has big implications for the story of how our universe grew up. When you purchase ...

We could go out with a crunch, and not a bang. Contrary to popular belief, our universe may not be constantly expanding after all. A groundbreaking study by South Korean researchers suggests that dark ...

Andromeda and the Milky Way merge. NASA; ESA; Z. Levay and R. van der Marel, STScI; T. Hallas; and A. Mellinger Share Curious Kids is a series for children of all ages. If you have a question you’d ...

Researchers using the James Webb Space Telescope spotted huge stars leaking nitrogen in an early galaxy, hinting that such 'monster stars' might have been the source of ancient supermassive black ...

It’s always amazing, and more than a little humbling, when the universe reminds us that our “common sense” is provincial, falling apart on cosmic scales. If you’re on the surface of Earth—and I’m ...

Chris Impey has received funding from NASA, NSF, Howard Hughes Medical Institute, and the Templeton Foundation. If you look across space with a telescope, you’ll see countless galaxies, most of which ...
