Have you ever wondered how astronomers measure the distance to other objects in the universe? How do they make claims that this nebula is 1,500 light years distance or that galaxy is 2.5 million light ...

Have a look round your living room. Everything around you is made up of molecules - just as you are. When they are put together, the molecules act as the building blocks of life. Every single building ...

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 ...

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 ...

Despite a century of measurements, astronomers can’t agree on the rate at which the universe is expanding. A technique that relies on measuring distances to a specific type of aging star in other ...

Do scientists need to re-examine the basic model of the universe? Using new measurements of cosmic distances, astronomers have refined their calculation of the Hubble Constant, a number that describes ...

Recreation of Baryon Acoustic Oscillations. After a complex statistical analysis of some one million galaxies, a team of researchers at several Chinese universities, and the University of Cordoba was ...

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 ...
