James Webb Space Telescope reveals secrets of planet formation and black hole feeding

New observations from the James Webb Space Telescope (JWST) are providing significant insights into the mechanics of planetary formation and the feeding processes of supermassive black holes.

A study of 72 young, Sun-like stars reveals that planet formation is a race against time. Researchers found that protoplanetary disks lose gas through various mechanisms, such as magnetically driven jets and photoevaporation. If gas dispersal occurs too quickly, developing planets may fail to accumulate the mass necessary to become gas giants like Jupiter or Saturn.

In a separate discovery, JWST has provided the clearest view to date of gaseous filaments connecting a galaxy’s atmosphere to the rotating disk of a central supermassive black hole. By observing the galaxy NGC 4696, astronomers identified an S-shaped swirl of gas approximately 800 light-years across. This observation supports the hypothesis of a self-regulating cycle where gas cools into filaments and falls back toward the black hole, providing a continuous food supply.
