"Using the new common signal, we can determine how much of what we're seeing is cosmic glare from light bouncing off the hood ...

Scientists Teleported Light for the First Time in History, Say It Could Done Across Galaxies Since the dawn of astronomy, ...

Important to any analogy is an understanding of its limitations. Some flaws are obvious: A balloon is small enough to fit in ...

This process gradually cleared the fog of neutral gas, allowing ultraviolet light to travel freely and making the universe transparent to light. ・The cosmic dawn set the stage for the large ...

These bubbles of transparent, ionized gas then expanded and merged together, allowing light to then travel far throughout the universe. Even as they answered the question of what was ultimately ...

While light can now travel in all directions across the universe, rendering it transparent, the early universe was shrouded in hydrogen, which absorbed the light emitted by the first stars and ...

That made the universe transparent to most light less energetic than a particular ultraviolet wavelength — including visible light — for the first time. But with no stars around, the cosmos ...

Ionized hydrogen atoms are transparent to electromagnetic radiation ... The researchers used Webb to observe some of the oldest objects in the universe, which originated early in the era of ...

Over the next few hundred million years, as stars began to shine, their light ionised the hydrogen and helium, enabling photons to flow freely and making the universe transparent, though the exact ...

But more than just an arresting sight, the view has helped astronomers determine what sparked the Epoch of Reionization, the period when the opaque universe gave way to the transparent one.

By about t + 370,000 years, neutral hydrogen formation had wound itself down, leaving the Universe transparent for the first time. But not all the matter formed by Big Bang nucleosynthesis ...
