March 12 (UPI) --Scientists have reconstructed a cosmological model to fit the complex arithmetic of the Antikythera Mechanism, the world's first analogue computer. One of the most sophisticated ...

DESI has made the largest 3D map of our universe. The Earth is at the central vertex, and every dot is a galaxy. DESI collaboration and KPNO/NOIRLab/NSF/AURA/R ...

For decades, astronomers have relied on Einstein’s theory of relativity to explain the expansion of the universe, assuming that dark energy—a mysterious force making up 70% of the cosmos—remains ...

How do you measure dark matter, which by definition emits no light? Watch how it impacts things that you can see — specifically, how light from distant galaxies bends around it, as predicted by ...

We can model the motions of planets in the Solar System quite accurately using Newton’s laws of physics. But in the early 1970s, scientists noticed that this didn’t work for disc galaxies — stars at ...
