"Deadly Giants: The Life-Threatening Impact of Giant Planets in Alien Solar Systems"

Giant gas planets in other solar systems can disrupt the habitable zones of their Earth-like neighbors, making it unlikely for life to exist. The pull of massive planets can kick smaller planets out of their stable orbits, preventing them from remaining in the habitable zone where liquid water can exist. Computer simulations show that only a few areas within the habitable zone would not be affected by the gravitational pull of giant planets. Additionally, a planet in a nearby star system, GJ 357 d, previously thought to be in the habitable zone, is likely much larger than initially believed, making it unsuitable for hosting life as we know it. These findings highlight the rarity of the conditions necessary for life to exist in other solar systems.
