The universe’s expansion rate was supposed to be a solved problem, yet the latest high precision map of the early cosmos has pushed one of modern astronomy’s sharpest conflicts back to center stage.

A Simon Fraser University cosmologist believes his team's new research may bring them a step closer to cracking one of ...

The universe is expanding, but astronomers still cannot agree on exactly how fast. That mismatch, known as the Hubble tension, has turned a seemingly simple number into one of the biggest headaches in ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, ...

In the sprawling Hydra constellation, 137 million light-years away, lies NGC 3285B—a dazzling spiral galaxy recently spotlighted by NASA’s Hubble Space Telescope. This cosmic beauty orbits the edges ...

NEW YORK (AP) — NASA’s Hubble Space Telescope got a rare look at the aftermath of two cosmic collisions — and helped scientists solve a decades-old mystery. Survivors juggle sorrow, hope on NASA’s day ...
