    This image contains the most distant black hole ever detected in X-rays, a result that may explain how some of the first supermassive black holes in the universe formed. This discovery was made using X-rays from NASA’s Chandra X-ray Observatory (purple) and infrared data from NASA’s James Webb Space Telescope (red, green, blue). The extremely distant black hole is located in the galaxy UHZ1 in the direction of the galaxy cluster Abell 2744. The galaxy cluster is about 3.5 billion light-years from Earth. Webb data, however, reveal that UHZ1 is much farther away than Abell 2744. At some 13.2 billion light-years away, UHZ1 is seen when the universe was only 3% of its current age.

    Webb has discovered a 3000-mi (4800-km) wide jet stream over Jupiter’s equator, above the main cloud decks. This newly discovered Jovian jet stream travels at 320 miles per hour, 2 times the winds of a Category 5 hurricane on Earth! It’s located around 25 miles (40 kilometers) in altitude, in Jupiter’s lower stratosphere. Other missions have looked at Jupiter’s atmosphere and detected the lower, deeper layers, where there are gigantic storms and ammonia ice clouds. Webb’s sensitive near-infrared eye reveals new detail in the higher-altitude layers, 15-30 mi (25-50 km) above the cloud tops.
