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 ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new ...

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 ...

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 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 ...

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 ...

For billions of years, gravity has been the cosmic architect, shaping the universe from a chaotic primordial soup after the Big Bang into the intricate web of galaxies we see today. Now, scientists ...

Peer into the sky through a powerful telescope, and beyond the glare of the Milky Way, you can make out the faint glow of distant galaxies. These galaxies clump together in dense clusters joined by ...

Discover why astronomy and cosmology are the universe's mapmakers. Discover how scientists trace galaxies, the cosmic web, and the large-scale architecture of our entire existence in three dimensions ...
