Astronomers study planetary evolution and rapid planet formation

Recent astronomical studies are providing new insights into planetary evolution and the potential for extraterrestrial life. Researchers from Northern Arizona University suggest that the age of a planet does not automatically guarantee the presence of advanced intelligent life. A new study indicates that the availability of energy for photosynthesis may be a more critical factor in evolutionary speed than the mere passage of billions of years. By examining cumulative photosynthesis across 29 exoplanets, scientists found that energy availability from stellar light is a decisive variable in biological development.

In a separate discovery, astronomers have confirmed the existence of Elias 2-24 b, one of the youngest known planets. This Jupiter-sized world is less than one million years old and is currently forming within a swirling disk of gas, dust, ice, and rocky material. The discovery, involving data from the Keck Observatory and researchers from the University of Diego Portales, suggests that large planets may form much faster than current astrophysical models predict.
