A new measurement could change our understanding of the universe

The universe is expanding, but how fast exactly? The answer appears to depend on whether you estimate the cosmic expansion rate—referred to as the Hubble's constant, or H0—based on the echo of the Big Bang (the cosmic ...

Webb telescope discovers oldest galaxies ever observed

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 Tuesday.

Artificial intelligence finds the first stars were not alone

By using machine learning and state-of-the-art supernova nucleosynthesis, a team of researchers have found the majority of observed second-generation stars in the universe were enriched by multiple supernovae. Their findings ...

Evidence for the existence of a deeply bound dibaryon, built entirely from beauty quarks

Dibaryons are the subatomic particles made of two baryons. Their formations through baryon-baryon interactions play a fundamental role in big-bang nucleosynthesis, in nuclear reactions including those within stellar environments, ...

The multiverse: Our universe is suspiciously unlikely to exist—unless it is one of many, says physicist

It's easy to envisage other universes, governed by slightly different laws of physics, in which no intelligent life, nor indeed any kind of organized complex systems, could arise. Should we therefore be surprised that a universe ...

Astronomers observe lone distant galaxy that appears to have consumed all of its former companions

Over 13 billion years ago, the first galaxies in the universe formed. They were elliptical, with intermediate black holes (IMBHs) at their centers surrounded by a halo of stars, gas, and dust. Over time, these galaxies evolved ...

The universe may have started with a dark Big Bang

The Big Bang may have not been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter particles. And we may be able to ...
