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 ...

In a remarkable revelation, NASA and its international partners have recorded a signal from deep space that traveled an astonishing 13 billion years to reach Earth. This fleeting 10-second gamma-ray ...

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.

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.

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 ...

Astronomers have pulled off an unprecedented feat: detecting ultra-faint light from the Big Bang using ground-based telescopes. This polarized light scattered by the universe's very first stars over ...

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 ...

A radio signal from the early universe could allow us to understand how everything that surrounds us began. The signal – known as the 21-centimetre signal – could finally let us understand how the ...

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 ...
