New ultra-precise measurements have confirmed the cosmos is expanding faster than models based on the early universe predict, while a separate study has dramatically shortened estimates of how long the universe itself will last.
Astronomers have long observed a mismatch in the universe’s expansion rate depending on how it is measured. Local observations of nearby galaxies point to a faster rate, while data from the early universe, such as the cosmic microwave background, suggest a slower pace. This longstanding puzzle is known as the Hubble tension.
A major international collaboration, the H0 Distance Network (H0DN), hasnow producedone of the most accurate local measurements yet. The team combined decades of independent distance measurements—including observations of red giant stars, Type Ia supernovae, and different galaxy types—into a unified “Local Distance Network.” Their result: the Hubble constant stands at 73.50 ± 0.81 kilometers per second per megaparsec, with precision just over 1 percent.

“This isn’t just a new value of the Hubble constant,” the collaboration notes, “it’s a community-built framework that brings decades of independent distance measurements together, transparently and accessibly.”
The findings, published April 10, 2026, inAstronomy & Astrophysics, strengthen the case that the discrepancy is not due to a simple measurement error.
“This work effectively rules out explanations of the Hubble tension that rely on a single overlooked error in local distance measurements,” the authors conclude. “If the tension is real, as the growing body of evidence suggests, it may point to new physics beyond the standard cosmological model.”
Dr Kathy Romer of the Dark Energy Surveycommented, “The universe is not only expanding, but it is expanding faster and faster as time goes by.” She added, “What we’d expect is that the expansion would get slower and slower as time goes by, because it has been nearly 14 billion years since the Big Bang.”
Separate researchusing the largest-ever 3D map of the universe from the Dark Energy Spectroscopic Instrument (DESI) has produced hints that dark energy—the force accelerating cosmic expansion—might not be constant but could be weakening over time.
