In the journey of exploring the universe, identifying planets capable of sustaining life has always been a top priority. However, recent studies have revealed the phenomenon of “tidal heating”—the rise in a planet’s internal temperature caused by gravitational forces between the planet and its host star—which can significantly alter the habitable zones within our galaxy. “Tidal heating not only pushes planets out of the ideal conditions for life but also completely changes their geological and climatic structures,” according to Rory Barnes, an astrobiologist at the University of Washington.
“The number of potentially habitable planets could decrease by as much as 50% due to the effects of tidal heating,” Barnes presented at the American Astronomical Society conference in 2023. This is especially critical when considering planets orbiting red dwarf stars, which constitute the majority in the Milky Way.

The habitable zone—often referred to as the “Goldilocks Zone”—is typically defined as the distance from a star where liquid water can exist on a planet’s surface. For red dwarf stars, this zone is located very close to the host star, where tidal forces are significantly stronger. The gravitational pull stretches the planet’s crust as it orbits in an elliptical path, causing internal friction and raising the planet’s internal temperature. This process can lead to intense volcanic activity, the release of toxic gases, or even the complete evaporation of surface water.
“Essentially, tidal heating acts as a planet’s self-destructive mechanism,” Barnes emphasized.

However, this phenomenon is not always a negative factor. Some planets may achieve a state of balance where volcanic activity helps sustain temperatures and creates an atmosphere suitable for life. This is particularly important for red dwarf stars, where the light is much weaker compared to the Sun. For instance, greenhouse gases released from volcanic eruptions could trap heat and prevent the planet’s surface from freezing.
Such studies not only provide new perspectives on the potential for extraterrestrial life but also underscore the fact that our understanding of the physical laws of the universe remains limited. Perseverance in research will continue to bring humanity closer to answering the question: “Are we truly alone in the universe?”
