Dark Energy is causing our universe to expand but we still don’t know why – It will stretch the cosmos so much that one day no one will see stars

Using a high-resolution cosmological simulation called ASTRID, the team modeled the evolution of the universe as it appeared about 11 billion years ago

The cosmic web is a gigantic network of crisscrossing celestial superhighways that connects nearly everything in the universe

A massive galaxy far from Earth seems to be entirely devoid of dark matter, contrary to all accepted cosmological models

Astronomers have discovered the most distant black hole yet using the Webb Space Telescope, but that record isn't expected to last.

The black hole is at the center of a galaxy dating to within a mere 570 million years of the Big Bang. That's 100 million years closer to the beginning of the cosmos than a black hole identified in 2021 by a Chinese team using a telescope in Chile.

A European space telescope blasted off Saturday on a quest to explore the mysterious and invisible realm known as the dark universe.

Europe's Euclid space telescope is scheduled to blast off Saturday on the first-ever mission aiming to shed light on two of the universe's greatest mysteries: dark energy and dark matter.

The launch is planned from Cape Canaveral in Florida at 11:12 am local time (1512 GMT) on a Falcon 9 rocket of the US company SpaceX.

There are two parallel universes. On the one hand, a digital world operating at the speeds of TikTok or Twitter, standing ecstatic, enthusiastic or skeptical in front of innovations in artificial intelligence, harnessing the possibilities of ChatGPT, trying to perceive the changes taking place in everything from the environment to employment.

Astronomers said on April 26 that for the first time they have confirmed what ignites quasars, the brightest and most powerful objects in the universe, which put galaxies in their "death throes."

These celestial behemoths form when two galaxies smash into each other, the astronomers said, warning that this could be the Milky Way's fate in a few billion years.

The James Webb Space Telescope has discovered the four most distant galaxies ever observed, one of which formed just 320 million years after the Big Bang when the universe was still in its infancy, new research said on April 4.
