Scientists have demonstrated the fastest distance measurement so far. The researchers demonstrated on-the-fly sampling of a gun bullet profile with micrometer accuracy. The experiment relied on a ...

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 ...

Have you ever wondered how a robot navigates a cluttered room or how a drone maintains its altitude with pinpoint accuracy? The secret lies in the tools used to measure distance, an often-overlooked ...

A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and ...

It’s a bit mind-bending to realise that everything we know about the scale of the universe comes from people stuck […] ...

Google Earth allows you to measure the distance between two points on the Earth, as well as the circumference of a circular section of the ground — or even the elevation of a mountain. But in order to ...
