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

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 ...

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

A team of astronomers has discovered the largest and most distant water reservoir ever detected in the universe, surrounding a quasar more than 12 billion light-years away. The finding pushes the ...

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 ...

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 ...

To the unaided human eye, the night sky is resplendent with over 9,000 individual points of light, but that perspective covers only a bare fraction of the universe. When you purchase through links on ...

Wormholes, conceptual tunnels slicing through spacetime, offer a theoretical shortcut between two distant cosmic points.

If you were to go as far out into space as you can imagine, what would you encounter? Would there be a limit to how far you could go, or could you travel a limitless distance? Would you eventually ...

For the first time, an international research team led by the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has demonstrated that applying pixelized strong-lensing ...

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 ...
