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 ...

JWST observations suggest Population III stars may have formed 13 billion years ago, helping trace early galaxies.

With its sharp observation and wide-field view, Euclid has already found more than 1.2 million large galaxies and obtained details of their morphology.
