Caption How the same region of the Universe would look in terms of the amount of stars for different values of the dark energy density. Clockwise, from top left, no dark energy, same dark energy ...

The James Webb Space Telescope has found perhaps its most profound discovery to date. The uncovered preferred direction for ...

Water may have formed less than 200 million years after the Big Bang, suggesting some conditions for life existed far earlier than previously thought.
