What allows us to observe the Epoch of Reionization, and up to what age of the universe can this be observed?

February 21, 2025

The Epoch of Reionization refers to the period in the early universe when the first stars and galaxies formed, and their radiation ionized the surrounding hydrogen gas. We are able to study this epoch through observations of distant astronomical objects. Light from these objects travels for billions of years before reaching us, essentially allowing us […]

The appearance of constellations would be significantly altered when viewed from a different solar system. Here on Earth, constellations are patterns formed by various stars that seem to be adjacent to each other from our perspective. However, stars are at vastly different distances from Earth, spread across the Milky Way. If you observed the night […]
