A proposed cosmology model argues that the universe may contain ordinary matter alone, without dark matter or dark energy.

A recent paper claimed that dark energy might not exist. But new research suggests this conclusion was premature.

Some black holes roaming the Universe today may actually be older than the Big Bang. A new cosmic “bounce” model suggests the ...

After a multi-decade-year mission to understand the nature of the universe, a telescope perched in the mountain plateaus of northern Chile said goodbye in 2022. Now, its final data release is ...

For centuries, cartographers have sought to map Earth’s land masses and seas to better understand the world and their place in it. Now, astrophysicists have taken a major step toward doing the same ...

A tiny UK-developed satellite, roughly the size of a small carry-on suitcase, could help answer one of the biggest questions in cosmology: What happened during the roughly 150 million years of the ...

Let’s say you have a baby. Maybe you really do, maybe you don’t. But Dan Scolnic, a cosmologist at the University of Chicago, does have one, and perhaps that's why a hypothetical baby helps him ...

It’s supposed to be the “gold standard” of evidence supporting the standard model of cosmology – including dark matter, dark energy and the exponential expansion after the big bang known as inflation.

About a year after launching into orbit around the Sun, the James Webb Space Telescope began imaging an abundance of little red dots, which scientists called, um, “little red dots.” I know—not only is ...

Given how unfathomably large the universe is, it is perhaps understandable that we haven’t yet cracked all its secrets. But there are actually some pretty basic features, ones we used to think we ...

RUDN University astrophysicists have gathered the most important discoveries of modern cosmology from 1917 to our time. The collected data became an introduction to Philosophical Transactions of the ...

An expert shares his personal reminiscences of the evolution of the subject of cosmology over six decades. He tells of the increase in our confidence in the standard model of cosmology to the extent ...
