The team explores one of the greatest discoveries of modern astronomy - that our universe is expanding - and the new ...

For more than two decades, the standard model of cosmology has stood as a reliable guide to the universe. Known as Lambda ...

New data on baryon acoustic oscillations strengthen the case for a local cosmic void. The finding offers a possible solution to the Hubble tension. When we look at the night sky, it can appear as ...

This expansion traces back to the Big Bang, approximately 13.8 billion years ago, which marked the beginning of the universe’s rapid expansion from an extremely dense and hot state.

It started with a hunch. Or more accurately, a glow. Scientists using NASA’s James Webb Space Telescope were combing through ...

To astronomers in the 1990s, these three facts were self-evident: The universe is expanding; all the matter in the universe ...

That cosmologists cannot agree on one of the most elementary facts about the universe is striking enough. But that ...

For years, scientists believed there were about 100 billion galaxies in the observable universe, but this new research increases that number by tenfold, expanding our understanding of the cosmos ...

This became the Hubble–Lemaître law, a simple but revolutionary equation showing that the universe is expanding. But here’s the subtlety: the galaxies are not flying through space as bullets through ...

Modern cosmology has precisely measured the universe's properties, yet dark matter and dark energy remain profound mysteries.

In fact, scientists think that the Big Bang did not happen at a single location in space. It occurred everywhere at once. This is a challenging concept to grasp, but Arthur Eddington offered an ...

With the universe constantly expanding, scientists have a hard time finding where its center is.
