It’s always amazing, and more than a little humbling, when the universe reminds us that our “common sense” is provincial, falling apart on cosmic scales. If you’re on the surface of Earth—and I’m ...

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 ...

Many people, even astronomy enthusiasts, routinely wonder about the frequent reports of UFOs, or UAPs (unidentified anomalous phenomena), frequently spotted in the sky and sending people into fits ...

Hi folks, tune in every week of 2023 for the best in astronomy from Astronomy Editor Dave Eicher, brought to you by Celestron. Dave’s weekly video series will cover all the latest sky events, ...

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 ...

The most massive structure in the Universe, the Hercules-Corona Borealis Great Wall, challenges cosmological models with its colossal scale. A recent study using gamma-ray bursts, the most energetic ...

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 ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new ...

Velocity streamlines within the reconstructed volume, with colored envelopes associated with the prominent nearby basins of attraction. The map and streamlines have been cropped to the region covered ...

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.

Cosmic web Created using data from the JWST, this map shows how dark matter acts as the hidden framework on which visible ...
