An international team of scientists has analyzed archive data for powerful cosmic explosions from the deaths of stars and found a new way to measure distances in the distant universe. Led by Maria ...

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 ...

The largest 3D map of the universe reveals over 47 million galaxies, but dark energy remains an unsolved mystery.

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 ...

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 ...

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 ...

Most scientists think that everything that we know and experience began with the Big Bang, 14 billion years ago. But how can ...

Nearby, the stars and galaxies we see look very much like our own. But as we look farther away, we see the Universe as it was in the distant past: less structured, hotter, younger, and less evolved.

Astronomers have analyzed archive data for powerful cosmic explosions from the deaths of stars and found a new way to measure distances in the distant Universe. An international team of 23 researchers ...
