The most precise accounting yet of dark energy and dark matter

Astrophysicists have performed a powerful new analysis that places the most precise limits yet on the composition and evolution of the universe. With this analysis, dubbed Pantheon+, cosmologists find themselves at a crossroads.

Strange new 'species' of ultra-red galaxy discovered

In the distant reaches of the universe, almost 13 billion light-years from Earth, a strange species of galaxy lay hidden. Cloaked in dust and dimmed by the intervening distance, even the Hubble Space Telescope couldn't spy ...

James Webb's 'too massive' galaxies may be even more massive

The first results from the James Webb Space Telescope have hinted at galaxies so early and so massive that they are in tension with our understanding of the formation of structure in the universe. Various explanations have ...

Einstein's two mistakes

Scientific research is based on the relationship between the reality of nature, as it is observed, and a representation of this reality, formulated by a theory in mathematical language. If all the consequences of the theory ...

New 3-D map will help solve long-standing cosmic mysteries

A new study led by ANU has created a 3D map of the magnetic field in a small wedge of the Milky Way galaxy, paving the way for future discoveries that will improve our understanding of the origin and evolution of the Universe.

The distant cosmos as seen in the infrared

(Phys.org) —At some stage after its birth in the big bang, the universe began to make galaxies. No one knows exactly when, or how, this occurred. For that matter, astronomers do not know how the lineages of our own Milky ...
