We see these galaxies as they were over 13.45 billion years ago, just between 330 and 350 million years after the Big Bang.

We all know the universe contains a vast array of elements, ranging from light gases, such as helium, to heavy metals, like lead. But where did all of the elements come from?

A new method to detect Baryon Acoustic Oscillations in the universe could help measure cosmic distances more accurately.

Astronomer Carl Sagan once said that humanity is "made of star stuff." In a new video, astrophysicist Suzanna Randall explains what that actually means and where the elements in our body come from.

Thanks to the James Webb Space Telescope, scientists have begun getting the goods on Earendel, the most distant star ever detected.

The coming Square Kilometre Array could shed light on mysterious dark matter, revealing the role it played in the formation of the universe's first galaxies.

Just as Darwin used the fossil record to piece together the evolution of life on Earth, scientists can use a "cosmic fossil," the universe's first light, to understand how the cosmos evolved.
