Light takes time to travel, and that simple truth turns the James Webb Space Telescope into a time machine. When Webb opens its golden eye, it doesn’t just catch distant starlight – it intercepts messages that left their sources when Earth was still cosmic dust. In newsroom terms, every image is a breaking story filed ...
The cosmic microwave background represents the earliest visible light in our universe, a fading echo from when the cosmos was just a child. For decades, scientists viewed this ancient radiation as a stable cosmic record. Yet recent observations are revealing something startling: this primordial light in ways we never expected. Picture the universe as it ...
The universe’s most ancient stars have held their secrets for over 13 billion years, but recent research is forcing astronomers to completely rethink what those earliest celestial beacons were actually like. For decades, scientists believed these primordial giants were uniformly massive monsters that burned bright and died young. Now, cutting-edge computer simulations and unexpected molecular ...
