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 ...

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 ...

While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets ...

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 ...

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 ...

Astronomers have, for the first time, pinned down both the mass and distance of a planet that drifts through the galaxy ...
