A team of physicists and engineers at China's Hefei National Laboratory has succeeded in conducting the first instance of precise absolute distance measurement over a path exceeding 100 km. The group ...

A new laser range-finding technique, inspired by quantum physics, that can measure distances under strong solar background has been demonstrated by researchers at the University of Bristol. The team ...

Pune: Researchers have devised a clever method to correct distance errors in galaxy measurements, making our maps of the ...

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 ...

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 ...

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 ...

Our Universe consists of hundreds of billions of galaxies, and for nearby galaxies, distances are mainly measured by classical Cepheids and RR Lyrae (RR Lyr) stars. RR Lyr stars are pulsating variable ...

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 ...
