Exploring the Tectonic Potential of LHS 3844b: A New Hope for Alien Life
Written on
Chapter 1: The Quest for Exoplanets
The search for exoplanets has yielded a wealth of discoveries, ranging from gas giants much larger than Jupiter that scorch as they orbit too closely to their stars, to diminutive worlds smaller than our Moon. Among these celestial bodies, we've even identified a super-Earth enveloped in a hydrogen and helium atmosphere. Yet, the hunt for a planet with the vital elements conducive to alien life continues. Recently, however, we have stumbled upon an intriguing exoplanet that may harbor essential components for advanced extraterrestrial beings, and the findings may surprise you.
Chapter 2: The Discovery of LHS 3844b
Discovered by NASA's TESS (Transiting Exoplanet Survey Satellite), LHS 3844b was identified through its dimming effect on the light of its host star, a Red Dwarf known as LHS 3844. Observations revealed that this peculiar exoplanet is not merely another rock in space; it presents characteristics unlike any other planet in our Solar System.
LHS 3844b boasts a low albedo, indicating a surface reminiscent of the Moon, and its mass is approximately 2.25 times that of Earth. The planet orbits extremely close to its star—about 0.006 times the distance of Earth's orbit—resulting in a year lasting less than half a day. If I were on LHS 3844b, I would already be over 18,250 years old!
Section 2.1: Simulating the Alien Environment
A team from the American Astronomical Society conducted simulations to explore the unique conditions of LHS 3844b. These simulations provide valuable insights into the dynamics of this alien world, which orbits a star significantly closer than Earth does to the Sun. The results suggest the exoplanet may have active tectonics and volcanism, features that are typically taken for granted on Earth but are crucial for the emergence of life.
Section 2.2: The Role of Hydrothermal Vents
Current theories regarding life's origins on Earth point to organic chemistry occurring in hydrogen-rich hydrothermal vents. These locations provided the necessary building blocks for life, thriving in warm water with ample chemical energy. It's widely accepted that these vents may have been instrumental in the emergence of life on our planet.
Interestingly, we also know of another celestial body with hydrothermal vents—Enceladus, a moon of Saturn—where a subsurface ocean lies beneath an icy crust. The gravitational influence of Saturn and its moons heats the rocky core, leading to hydrothermal activity. While Enceladus is our best bet for finding simple life forms, its lack of true tectonic activity limits the complexity of potential life.
Chapter 3: The Importance of Tectonics
The combination of tectonics and life is fascinating. Throughout Earth's history, geological activities have significantly influenced biological evolution. The Ediacaran Period, for instance, saw the emergence of simple multicellular organisms, but substantial evolutionary leaps awaited the activation of tectonic processes.
During the Cambrian Explosion, geological upheaval created nutrient-rich environments conducive to the diversification of life. The interplay between tectonics and biology may be a fundamental requirement for fostering intelligent life.
Section 3.1: The Tectonic Landscape of LHS 3844b
For advanced extraterrestrial life to develop, geologically active environments like those on LHS 3844b are essential. This exoplanet stands out as the first we have identified with signs of tectonics, raising intriguing questions about its potential for life.
Chapter 4: The Harsh Reality of LHS 3844b
Despite the tantalizing possibilities, LHS 3844b is not likely to host advanced civilizations. The extreme conditions on the planet—intense heat, tidal locking, and a thin atmosphere—render it inhospitable. The proximity to its Red Dwarf star subjects the planet to scorching temperatures on one side and freezing conditions on the other.
The simulations indicate that while the day side may be dotted with volcanoes and tectonic activity, the dark side suffers from subduction and quakes, creating a dynamic yet unwelcoming environment.

In this video, we examine the potential for life on exoplanets, including LHS 3844b, and what it means for our understanding of alien ecosystems.
Chapter 5: The Future of Exoplanet Exploration
Although LHS 3844b may not support life as we know it, its discovery opens new avenues for research. The potential for tectonics on exoplanets like Proxima Centauri b offers hope for future explorations. As we continue to investigate these alien worlds, we might find planets that can sustain life and perhaps discover whether we share the cosmos with other intelligent beings.
So, as you admire the mountains and volcanoes on Earth, remember that these geological wonders could also exist on distant worlds, possibly nurturing their own forms of life.
