It’s always amazing, and more than a little humbling, when the universe reminds us that our “common sense” is provincial, ...

The universe’s expansion rate was supposed to be a solved problem, yet the latest high precision map of the early cosmos has ...

AUSTIN, Texas — An international team of astronomers led by Fritz Benedict and Barbara McArthur of The University of Texas at Austin has used Hubble Space Telescope to solve one of the biggest ...

The universe is expanding, but astronomers still cannot agree on exactly how fast. That mismatch, known as the Hubble tension ...

The universe is unimaginably vast. Even the nearest stars are incredibly far away. Our galaxy is just one of billions. Traveling vast cosmic distances requires immense energy. Key takeaways sponsored ...

The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us. This marks the edge ...

Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale. A group of researchers at the University of Waterloo and the ...

Scientists estimate that dark matter and dark energy together are some 95% of the gravitational material in the universe while the remaining 5% is baryonic matter, which is the “normal” matter ...

A team of scientists has predicted the science return from one of NASA’s Nancy Grace Roman Space Telescope’s groundbreaking planned surveys, which will analyze millions of galaxies strewn across space ...

Julian Muñoz has come up with a ruler to measure the early universe. A theoretical physicist, Muñoz studies the distant, dim period in the universe’s history known as cosmic dawn. That’s when stars ...

Einstein's theory of general relativity is our best description of the universe at large scales, but a new observation that reports a "glitch" in gravity around ancient structures could force it to be ...
