The Temperate Exoplanet LHS 1140 b Revealed as Best Candidate for Earth-Like Atmosphere
The use of the James Webb Space Telescope by scientists has led to the conclusion that the exoplanet LHS 1140 b may hold the greatest potential yet for the discovery of water and an Earth-like atmosphere. LHS 1140 b, a planet that is 1.7 times the size of Earth and located just 49 light-years away in the constellation Cetus, has emerged as one of the most promising exoplanets for the search for liquid water beyond our solar system.
Significant Findings through JWST Data
Discovered in 2017 by the MEarth Project, LHS 1140 b was initially believed to be a mini-Neptune gas giant planet or a rocky, terrestrial planet. However, new data collected by the JWST in December 2023 suggests that the planet may possess an atmosphere and even a liquid water ocean. Charles Cadieux, a doctoral student at Université de Montréal and the lead author of a paper due for publication in The Astrophysical Journal Letters, considers LHS 1140 b to be the best candidate out of all known temperate exoplanets to confirm the existence of liquid water on the surface of an alien world outside of our solar system.
Speculations About the Exoplanet’s Composition
Although it is estimated that 10 to 20% of LHS 1140 b’s mass constitutes water, it is unclear whether the planet is an ice or “snowball” world. Due to the fact that the planet is tidally locked to its star, with one side always facing the star, there is a possibility of a liquid ocean existing on its permanently dark side. Based on these speculations, experts suggest that the potential ocean would have a considerable diameter of 2,500 miles and a surface temperature of about 68 degrees Fahrenheit.
The Quest for Habitable Exoplanets and LHS 1140 b’s Characteristics
LHS 1140 b, classified as a “super-Earth” due to its mass being approximately seven times greater than that of Earth, orbits a red dwarf star, which is one of the most common types of stars in the Milky Way. Despite the planet taking only 25 days to orbit a star that is much smaller and dimmer than our sun, its position within the ”habitable zone” around its star allows for the potential existence of liquid water. This is significant because water is considered essential to life. Additionally, comparative data demonstrates that LHS 1140 b’s star, which is calmer and less active than others, makes it easier to disentangle the exoplanet’s atmosphere from the signals caused by the star itself.
The Search for a Suitable Atmosphere
Scientists are hopeful about the possibility of LHS 1140 b possessing a nitrogen-rich atmosphere similar to that of Earth. However, they emphasize the need for more JWST observations to confirm the presence of nitrogen gas and to search for other gases. Given that JWST can only observe LHS 1140 b passing in front of its star eight times each year, it is anticipated that several years of observations will be required to detect carbon dioxide and confirm the presence of liquid water on the planet’s surface.
In Conclusion
The newest advancements in space exploration and exoplanet research have brought LHS 1140 b to the forefront as a potential candidate for supporting life beyond our solar system. Further observations and studies are needed to confirm the existence of an Earth-like atmosphere and the presence of liquid water, but this discovery marks an important step in identifying habitable exoplanets outside our solar system.
