Signs of alien life? Groundbreaking discovery on planet K2‑18b
Astronomers have discovered potential signs of life on the planet K2-18b, which is 124 light-years away from Earth. Observations indicate that the atmosphere of this distant planet is rich in sulfur compounds, which are typically produced in biological processes.
For years, we've looked up at the sky with curiosity, wondering if we are alone in the universe. Recently, astronomers announced the discovery of potential signs of life on the planet K2-18b. Research conducted using the James Webb Telescope showed the presence of compounds that might suggest the existence of extraterrestrial life.
K2-18b is located in the habitable zone
According to the Science Alert portal, K2-18b is an exoplanet located in the so-called habitable zone, which means it may have liquid water. It is eight times more massive than Earth and 2.5 times larger. Scientists detected methane and carbon dioxide in its atmosphere, as well as weak signals of dimethyl sulfide (DMS). On our planet, compounds like dimethyl sulfide (DMS) and dimethyl disulfide are exclusively produced by living organisms. The primary producers of these compounds are microscopic marine algae known as phytoplankton.
Although the discovery sparked enthusiasm, some scientists remain skeptical. It is possible that this distant planet is too hot to support life. Experts point out that similar substances can also form without the involvement of life forms.
The potential significance of the discovery
Nikku Madhusudhan from the University of Cambridge, the lead author of the study, emphasizes that while the results are promising, further observations are needed. If confirmed, it could be a breakthrough in the search for life beyond Earth.
The future of exoplanet research
Even if K2-18b does not turn out to harbor life, the James Webb Telescope and the latest technologies may accelerate the discovery of life beyond Earth.
Scientists suggest that any potential extraterrestrial life may not resemble intelligent life forms but could be more like the microorganisms that inhabited Earth's oceans billions of years ago.
