NASA’s James Webb Space Telescope (JWST) has sparked global intrigue with a groundbreaking discovery detecting chemical signatures of gases on a distant exoplanet that on Earth are produced solely by biological processes.
This finding centered on the exoplanet K2-18b, located 124 light-years away fuels hope of uncovering life beyond our solar system aligning with centuries-old questions about extraterrestrial existence and even interpretations of Quranic verses hinting at life in the cosmos.
A Breakthrough Discovery
K2-18b, a sub-Neptune exoplanet 2.6 times Earth’s size, orbits a red dwarf star in its habitable zone, where conditions could allow liquid water—a key ingredient for life. Using JWST’s advanced infrared capabilities, scientists, led by Cambridge University’s Prof.
Nikku Madhusudhan, identified dimethyl sulfide (DMS) and possibly dimethyl disulfide (DMDS) in the planet’s atmosphere. On Earth, these gases are primarily produced by marine phytoplankton, suggesting microbial life may exist on K2-18b.
Earlier observations also confirmed methane and carbon dioxide, supporting the theory that K2-18b is a “hycean” world with a vast ocean beneath a hydrogen-rich atmosphere.
“This is the strongest evidence yet for biological activity beyond our solar system” Madhusudhan stated, though he cautioned that the findings are not definitive proof of life. The detection reported with a three-sigma statistical significance (99.7% confidence), requires further validation to reach the scientific gold standard of five-sigma.
Quranic Indications and Historical Context
Discovery resonates with interpretations of the Quran, which some scholars argue hints at extraterrestrial life. Surah Ash-Shura (42:29) mentions God creating “living creatures” in the heavens and Earth, while Surah At-Talaq (65:12) refers to the “seven heavens.”
Tafsir scholars suggest these “dabba” (creatures) may not be human but could indicate microbial or other life forms, as implied in Surah Al-A’raf (7:54). These verses revealed 1,400 years ago align with modern scientific quests fueling discussions about divine foresight in cosmic exploration.
Human curiosity about alien life dates back to Galileo’s 17th-century telescope, which expanded our view of the cosmos. Despite advancements since the 1950s question of life beyond Earth remains unresolved inspiring literature, films, and web series.
Past claims like Percival Lowell’s Martian canals or the 1976 Viking lander’s ambiguous results, have fueled skepticism, making JWST’s findings a pivotal moment.
Scientific Caution and Future Steps
While the detection of DMS and DMDS is unprecedented, experts urge caution. Dr. Jo Barstow from the Open University emphasized the high burden of proof for such a profound discovery noting that unknown geological processes could mimic these biosignatures. A 2024 study from UC Riverside suggested the DMS signal might overlap with methane, questioning its reliability.
Madhusudhan’s team plans 16-24 hours of follow-up JWST observations to confirm the findings. “We’re entering the era of observational astrobiology,” he said, highlighting the telescope’s ability to analyze distant atmospheres. If validated, this could redefine our understanding of life’s universality.
Broader Implications
The search for extraterrestrial life extends beyond K2-18b. NASA’s ongoing missions explore Mars, Venus, and icy moons like Europa for habitable conditions. Last year’s controversial display of alleged “alien” remains in Mexico and NASA’s $1 billion UAP study led by Bill Nelson underscore the topic’s complexity. Nelson personally believes alien life exists but stresses the need for robust evidence.
JWST, operational since 2022, continues to revolutionize exoplanet research. Its ability to detect carbon-based molecules in K2-18b’s atmosphere in 2023 set the stage for this discovery, marking a leap in our quest to answer one of humanity’s oldest questions: Are we alone?

Germany Warns Israel Against Permanent Gaza Settlements
In a separate development, Germany has issued a stern warning to Israel against establishing permanent settlements in Gaza. This follows Tel Aviv’s announcement that the Israeli military would remain in Gaza’s security zones indefinitely.
The German government’s caution highlights growing international concern over escalating tensions in the region.
