A new study suggests that during a potential phase of primordial matter domination, particle interactions may have led to the formation of the universe’s first compact cosmic objects. Less than a ...

What the researchers found, grimly, is that the universe has gotten gradually colder. Ten billion years ago, the average dust grain temperature in the sampled galaxies was warmer by about 10 degrees ...

“The Universe will just get colder and deader from now on,” added Douglas Scott, study author and a cosmologist at the ...

In the blink of an eye after the Big Bang, the universe could have birthed strange new stars and black holes.

A team of astrophysicists has unveiled how colossal stars thousands of times more massive than the Sun shaped the earliest star clusters and galaxies. These short-lived giants not only forged the ...

UBC astronomers release a sneak peak of the most accurate measurements yet of key aspects of the Universe, including star ...

Astronomers may have just uncovered the earliest stars ever observed, potentially rewriting our understanding of the universe ...

Portuguese researchers predict that Europe's future space observatory will detect hundreds of thousands of supermassive black ...

A new model sheds light on the long-standing chemical mysteries found in globular clusters, the ancient archives of the universe. An international collaboration led by ICREA researcher Mark Gieles, fr ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

Stars come in many forms, but some types are so rare that only a handful exist in our galaxy. For example, O-type stars ...
