Promising Signs of Life Detected on Distant Planet K2-18b

A new exoplanet, HD 20794 d, has been confirmed just 20 light-years from our Solar System, sparking excitement over its potential habitability. According to astrophysicist Michael Cretignier from Oxford University, the planet, which is nearly six times Earth's mass, orbits a Sun-like star in the so-called "habitable zone," where conditions might allow liquid water to exist on its surface.
Though initial observations indicated a faint signal suggesting the planet's presence, later data analyses using the European Southern Observatory's ESPRESSO instrument confirmed its existence. While the exoplanet does spend part of its elliptical orbit in the habitable zone, it also strays to points where water could freeze, raising questions about its overall habitability.
Cretignier expressed enthusiasm about this discovery, noting the potential for future missions to capture images of the planet due to its relative proximity. The findings have been published in the journal Astronomy & Astrophysics, marking a significant step in the search for extraterrestrial life.
