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 ...

The cosmic distance ladder employs a series of methods to measure increasingly vast astronomical distances, with each technique building upon the previous one for verification. Parallax, using stellar ...

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 ...

A new application of laser technology known as two-way dual-comb ranging (TWDCR) has demonstrated with unprecedented precision in measuring the distance between instruments more than 100 kilometers ...

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 ...
