Abstract
Astronomers have now seen just how powerful the long-awaited James Webb Space Telescope (JWST) could be for revealing the chemical complexity of our universe. NASA and its partners—the European Space Agency, the Canadian Space Agency, and the Space Telescope Science Institute— released five images on July 12 that show scenes from across the universe, including the birth of stars, glowing nebulae, and tightly clustered galaxies. The data came from a suite of onboard instruments designed to capture infrared wavelengths of light from the earliest moments of the universe. The JWST has already outperformed the expectations of its engineers by snapping an image of the whirling galaxies of the cluster SMACS 0723 as it appeared 4.6 billion years ago (shown). In this photo, the gravity and dark matter from this galaxy cluster help magnify and distort the images of other ancient galaxies—those formed 13 billion years ago, soon after the big
