    K2-18b, Dünya'dan yaklaşık 124 ışık yılı uzaklıkta, kırmızı cüce yıldız K2-18'in yörüngesinde dönen bir ötegezegendir. Mini-Neptün olarak sınıflandırılan gezegen, Dünya'nın sekiz katı kütleye sahiptir ve yıldızının yaşanabilir bölgesinde yer alır.

    James Webb Uzay Teleskobu ile yapılan gözlemlerde, gezegenin atmosferinde canlı organizmalar tarafından üretilen dimetil sülfit (DMS) ve dimetil disülfit (DMDS) molekülleri tespit edilmiştir. Bu keşif, yaşamın varlığına dair güçlü bir kanıt olarak değerlendirilse de kesin sonuçlar için ek gözlemler gereklidir.

    K2-18b, hycean gezegen sınıfına aday gösterilir: hidrojen bakımından zengin atmosfere sahip okyanus dünyasıdır. Bilim insanları, bu tür gezegenlerin mikroskobik canlılar barındırabileceğini düşünmektedir.
