From the stars in our backyard to galaxies billions of light-years away, astronomers use a 'cosmic distance ladder' of methods to map the universe. Now, a global team has unified Hubble constant ...

A spectacular cosmic event nicknamed “SN Winny” could help solve one of astronomy’s biggest mysteries: how fast the universe is expanding. This rare superluminous supernova, located 10 billion ...

The most precise measurement yet shows the Universe is expanding faster than expected, deepening the Hubble tension. The ...

All the tools for measuring it in the local, recent Universe give fairly consistent results, around 72 to 74 kilometers per second per megaparsec. The tools for measuring it in the distant, early ...

The team reports the universe’s current expansion rate at 73.50 kilometres per second per megaparsec, with an uncertainty of ...

Scientists rely on two methods to measure the expansion of the universe: extrapolating from Cosmic Microwave Background (CMB) radiation, and making direct astronomical measurements. The mismatch ...

A comprehensive new study combines decades of research to reveal that we're missing an essential component in our ...

A comprehensive new study combines decades of research to reveal that we're missing an essential component in our understanding of how the universe works. When you purchase through links on our site, ...

The universe is stretching apart faster than our current theories of physics can explain, and a new study has just confirmed that the discrepancy is not a fluke. By funneling decades of data into the ...

One of the most accurate determinations of the local Universe's expansion rate to date has been produced by an international team of astronomers. One of the biggest problems in contemporary cosmology ...

Artist’s interpretation of the cosmic distance ladder — a succession of overlapping methods used to measure distances across the Universe, where each rung of the ladder provides information that can ...
