While the “Epoch of Reionization” sounds like the title of a sci-fi novel destined for a Hugo award, this very real era of the universe featured the first light from the very first stars.

The revolutionary James Webb Space Telescope and next-gen radio telescopes are probing what’s known as the epoch of reionization. It holds clues to the first stars and galaxies, and perhaps the ...

News Release 9-Apr-2022 Cosmic Dawn III recreates the Epoch of Reionization in unprecedented resolution The simulation aligns theoretical and observational data for the first time Reports and ...

“The Epoch of Reionization represents the last major transition of the universe in the story of cosmic evolution,” says theoretical astrophysicist Paul Shapiro, the Frank N. Edmonds, Jr Regents ...

The epoch of reionization wasn’t the first time that the universe was filled with electricity. Right after the big bang, the cosmos were dark and hot; there were no stars, galaxies, and planets.

After hundreds of millions of years, when almost all hydrogen in the universe became ionized, the epoch of reionization ended. Considering roughly 75% of all matter is hydrogen, this represents an ...

That's where early quasars enter the picture. "The epoch of reionization is considered the end of the universe’s dark ages," study team member and Chandra X-Ray Center scientist Thomas Connor said.

“The existence of merging quasars in the Epoch of Reionization has been anticipated for a long time. It has now been confirmed for the first time,” said Matsuoka.

The Epoch of Reionization was a critical epoch in the history of the Universe that marked the end of the cosmic dark ages and seeded the large structures we observe in our local Universe today.

Since the Epoch of Reionization, the 21 centimeter line has been red-shifted by the expansion of the universe to a wavelength 10 times as long -- about 2 meters, or 6 feet.

The simulation can be seen in the video below, showing the first light spreading through the darkness in a period called the epoch of reionization, around 13 billion years ago.
