We are not the universe’s physical center. But we are in the middle. We are between the smallest quantum particles and the largest cosmic structures. This realization lets us find new significance. It ...

These groundbreaking observations challenged the geocentric model of the universe and laid the foundation for modern astronomy. Over the next few centuries, telescopes evolved significantly. Isaac ...

Greek astronomer Claudius Ptolemy, who lived in Egypt, built upon Babylonian knowledge in his geocentric model of the universe. This model, which placed the Earth at the center of the universe, ...

New data reveals a 3-million-light-year filament connecting two galaxies, each of which hosts a supermassive black hole.

A study published in the Journal of Cosmology and Astroparticle Physics (JCAP) presents a methodology to test the assumption ...

A new way to study 3D maps of galaxies in the cosmos without compressing the data is revealing new information about the dark ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.

Dark matter can't be too heavy or it might break our best model of the universe, new research suggests. We have an abundance of evidence that something fishy is happening in the universe.

If scientists confirm an anisotropic expansion, it would challenge the assumption that the universe has no preferred directions.

Enabled by supercomputing, University of Pretoria (UP) researchers have led an international team of astronomers that has ...
