Astronomers Find 18 New Planets: Discovery Is the Largest Collection of Confirmed Planets Around Stars More Massive Than the Sun

The recent discovery of 18 new planets revolving stars more massive than our Sun brings us a step closer, however small, to finding other forms of life. We heave learned in class that stars more massive than our sun typically have shorter life spans due to the faster rate at which they undergo fusion, which means a shorter time for intelligent life to develop and exist in those star systems. However, larger mass stars have a wider habitable zone for which planets can reside in, resulting in more "chances" for life to develop on planets in said star systems.

The article notes that the newly-discovered planets have masses similar to Jupiter’s. It also states that planets like these are being found in wider, mainly circular orbits, all at least 0.7 AUs from the massive stars they orbit. Although it appears unlikely that habitable life could exist on the newly-found planets, the discoveries should still provide valuable information regarding planetary formation and the workings of our solar system.
