It is widely accepted that the universe is expanding at an accelerating rate, but now researchers say our measurements of the ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously ...

Trying to measure the size of the universe is no easy task. We know that the universe is expanding, though the exact rate of this expansion is not yet fixed. So one method that astronomers use to tell ...

The Universe might not exist forever. New observations by physicists indicate that it will one day reach its maximum size before beginning to contract. These results profoundly change our view ...

Astronomers have recently discovered that the Hercules–Corona Borealis Great Wall, a massive cosmic superstructure, might be much larger and closer to Earth than previously estimated. This remarkable ...

Space, as we all know, is big. In fact, it’s more than big; it’s vastly, hugely, mind-bogglingly big. But how big is that, exactly, and how do we go about assigning actual, quantifiable distances ...

The team of astronomers used the Keck I telescope to measure the distance to an ancient galaxy described as the farthest galaxy in the universe. The galaxy in question is called GN-z11, and it's both ...

A new set of precision distance measurements made with an international collection of radio telescopes have greatly increased the likelihood that theorists need to revise the “standard model” that ...

All fundamental forces operating on astronomical scales exhibit a decrease in strength with increasing distance. A hypothetical force, decreasing with distance slower than the inverse square law, ...

Astronomers have unveiled a new catalog of massive galaxy clusters, revealing new insight on the evolution of the universe ...

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 ...

A cosmic measurement technique independent of all others adds strong evidence pointing to a problem with the current theoretical model describing the composition and evolution of the Universe. A new ...
