The very first image captured by the James Webb Space Telescope is revealing some of the oldest stars and galaxies in the universe, including one that looks like a sparkler, according to new research.
Webb’s first stunning view was released by President Joe Biden on July 11 and it is “the deepest and sharpest infrared image of the distant universe to date,” according to NASA.
Webb’s first image shows SMACS 0723, where a massive group of galaxy clusters act as a magnifying glass for the objects behind them.
Called gravitational lensing, this created Webb’s first deep field view that includes incredibly old and faint galaxies. Deep field observations are lengthy observations of regions of the sky that can reveal faint objects.
