Besides being a point of light, a star is a luminous, spherical mass of plasma, enough to hold itself together under its own gravity. On its own, though, gravitational rounding isn't enough. What ...

A groundbreaking discovery has shed new light on star formation in the early universe, revealing a galaxy that forms stars at ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of ...

In a significant stride for cosmic evolution studies, astronomers have unveiled a galaxy that is churning out stars at a ...

Theorists have long wondered how massive stars–up to 120 times the mass of the Sun–can form without blowing away the clouds of gas and dust that feed their growth. But the problem turns out to be less ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such systems ...

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 ...

Chemistry in the first 50 million to 100 million years after the Big Bang may have been more active than we expected. This article was originally published at The Conversation. The publication ...
