Researchers from the Australian National University have developed a model that is the most comprehensive view of the history of the universe. The study highlights the change that the universe underwent from the moment of its formation 13.8 billion years ago to its current state, full of objects such as protons, atoms and galaxies
Harvard astronomers claim that the Milky Way's warped shape is due to an unbalanced halo of dark matter. This claim supports theories of a previous galactic collision and provides insights into the nature of dark matter. Credit: Stefan Payne-Wardenaar; Magellanic Clouds: Robert Gendler/ESO

"The effect of gravitational waves on pulsars is very weak and difficult to detect, but we built the credibility of the findings over time as we collected more data," said Caterina Cazziano, NANOGrav team member and senior lecturer at Caltech.
Impressively, a pair of supermassive black holes (top left) emit gravitational waves that propagate through the fabric of space-time. These gravitational waves compress and stretch the trajectories of radio waves that emit pulsars (in white). By carefully measuring the radio waves, a team of scientists recently discovered for the first time the gravitational wave background of the universe.

This galactic cluster boasts a variety of directions, with spiral galaxies like the one in the center of this image that are almost visible from above, and some spiral galaxies that are only visible as thin slices of light when viewed from the side. This is in addition to the gravitational lensing effect that allows viewing more distant galaxies

An image of about ten thousand galaxies is called: "Hubble's vast deep field". The image includes galaxies of a variety of ages, sizes, shapes and colors. About 800 of the small red galaxies may be the most distant galaxies to be seen. They were created when the universe was 13 million years old. The nearest galaxies - the luminosities with a distinct spiral or ellipse shape - are about a billion light-years away, when the universe was 800 billion years old. The image required 400 exposures taken during Hubble's 11.3 orbits around the Earth. The total exposure time was 24 days, between September 2003, 16 and January 2004, XNUMX. Photo: NASA, ESA, and S.
