Why it matters: Carbon is one of the primary building blocks of life as we know it. Therefore, the detection of carbon signs on celestial bodies other than Earth is always a significant discovery. Thanks to JWST's powerful instruments, scientists now have evidence that carbon should be abundant on one of the most promising targets for extraterrestrial life research.
In context: Supermassive black holes are among the most extreme phenomena that humans have discovered in outer space. They possess a mass hundreds of thousands, or even millions to billions of times the mass of the Sun, and they are responsible for powering unprecedented luminous events known as quasars.
