Pasadena, CA — Ohio State University researchers have found a way to measure distances to objects three times farther away in outer space than previously possible, by extending a common measurement ...

The cosmic distance ladder could soon have another rung. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. In around 5 billion years, the sun will ...

The universe is expanding; we’ve had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate. It’s no small feat to measure the ...

Physicists have improved the accuracy of a technique that uses variable stars to measure distances in the universe, providing a new figure for its expansion rate. When you purchase through links on ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you didn't know anything about the Universe beyond our own galaxy, ...

When it comes to measuring how fast the Universe is expanding, the result depends on which side of the Universe you start from. A recent study has calibrated the best cosmic yardsticks to ...

A long-running dispute about how fast our universe is expanding just became even more entrenched. New and more precise measurements of stars in the Large Magellanic Cloud, a satellite galaxy of the ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, ...

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 ...

Whenever you set out to solve a problem, there are a series of steps you have to take in order to arrive at the answer. Assuming your methods are sound and you don't make any major errors, the answer ...

The question of how fast the universe is expanding just keeps getting more confusing. Our two main methods of measuring the acceleration of the universe’s expansion disagree by nine per cent.

The gravitational waves emitted by the merger of black holes, when lensed by massive objects as the waves travel toward Earth can be used to calculate the rate at which the universe is expanding Photo ...
