A newly-detected spinning galaxy filament is reshaping our understanding of cosmic structure, gas flows, and the origins of ...

The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, ...

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

“The cosmos is also within us, we're made of star-stuff. We are a way for the cosmos to know itself.” - Carl Sagan Compared to the Sun, how big is the Earth? What is a scale model and how does it help ...

If you look across space with a telescope, you’ll see countless galaxies, most of which host large central black holes, ...

In the search to understand how the universe came to be, a new theory is rewriting the script. Instead of one massive, fiery birth like the Big Bang, this idea suggests the cosmos has been growing in ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...
