James Webb Space Telescope Reshapes Cosmology After Historic Christmas Launch
The James Webb Space Telescope launches from French Guiana and travels a million miles to its orbital post, where it transforms our understanding of the cosmos. By peering back to the cosmic dawn, the telescope reveals the earliest stars and challenges existing models of the universe.
The James Webb Space Telescope launches from a tropical launchpad in French Guiana and travels to a gravitationally stable spot a million miles away from Earth. This monumental $10 billion collaboration between NASA, the European Space Agency, and the Canadian Space Agency overcomes years of setbacks to reach its orbital destination at the edge of time itself.
Unlike any instrument before it, the telescope peers deep into the cosmic dawn to observe the very first stars forming just a few hundred million years after the Big Bang. It captures nearly 98 percent of the way back to the beginning of the universe, providing an unprecedented window into the distant past.
The continuous stream of data from the telescope promptly cracks open existing cosmological models and fundamentally reshapes our view of the cosmos. Researchers use this powerful tool to spot chemically primitive galaxies and map massive cosmic structures that rewrite the history of the early universe.
