Earlier this year, the Dark Energy Spectroscopic Instrument (DESI) completed observations that mapped 47 million galaxies ...

HONOLULU, Feb. 13, 2026 / PRZen / Study suggests “invisible wedge” in distance measurements could impact Hubble Tension resolution: 512 simulations fail to match observed propagation anomaly.

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

If, as novelist-philosopher Samuel Butler wrote in 1878, “a hen is only an egg’s way of making another egg”, then a galaxy may only be a black hole’s way of making another black hole. To put it ...

Physicists may have a brand-new way to measure the expansion rate of the universe — one of the biggest outstanding mysteries in cosmology — using space-time ripples predicted by Einstein. A new study ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Once dismissed as empty expanses between galaxies, cosmic voids are becoming one of the most promising tools for probing the universe’s biggest mysteries.

A few years ago, the internet caught alight with talk of a “vibe shift” in what counts as cool. Skinny jeans and minimalism were out; baggy trousers and messy hair were in. Cue a minor panic for ...
