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

A major international effort has produced an ultra-precise measurement of the Universe’s expansion rate, confirming it’s ...

The Dark Energy Spectroscopic Instrument (DESI) has successfully completed the largest high-resolution 3D map of the universe ...

The universe is expanding, and physicists cannot agree on how fast. In a preprint posted in late May 2026, the H0 Distance ...

Using a new framework, astronomers arrived at the most precise measurement of our universe’s expansion rate—but things still ...

A difference of a few kilometers per second might not sound like much. In cosmology, it has become one of the field’s most ...

For almost a century, we have known that the universe is expanding. For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates were the ...

Today scientists rely on two methods. The first is late-universe observation (or observation of the universe as we see it ...

The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the ...

AUSTIN (KXAN) — A commonly held belief that the universe is rapidly expanding may be wrong. A new paper published this month suggests the universe’s expansion might be slowing down and it could mean ...

The universe is expanding faster than previously thought, according to a team of astronomers using the Hubble Telescope. How much faster? Five to nine percent faster. Initially the expansion of the ...

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