After the Big Bang, the Universe entered a long, dark period before the first stars formed. During this era, hydrogen emitted a faint radio signal that still echoes today. New simulations show this ...

As mysterious as the Big Bang that gave birth to the universe is the brief but tumultuous period that immediately followed it. How did the cosmos transform from a uniform sea of darkness into a ...

In the vast, dark expanse of the universe, there lies a mystery about the first stars—massive, luminous celestial bodies that lit up the cosmos in its earliest stages. These stars, known as Population ...

Understanding how the universe transitioned from darkness to light with the formation of the first stars and galaxies is a key turning point in the universe's development, known as the Cosmic Dawn.

A mysterious radio signal has been traced to a galaxy far, far away. And, it's causing a stir among astronomers -- although nobody is sure what it is. Research published this week in the journal ...

Understanding how the universe transitioned from darkness to light with the formation of the first stars and galaxies is a key turning point in the universe’s development, known as the Cosmic Dawn.

Astronomers have shown that we will be able to learn about the masses of the earliest stars by studying a specific radio signal originating just a hundred million years after the Big Bang. (Nanowerk ...
