An article accepted for publication in the journal 'The Astrophysical Journal Letters' reports the results of a study of the exoplanet K2-18

An article accepted for publication in the journal "The Astrophysical Journal Letters" reports the results of a study of the exoplanet K2-18 b, including the discovery of carbon compounds such as methane in its atmosphere. A team of researchers led by Nikku Madhusudhan of the British University of Cambridge used observations conducted with the James Webb Space Telescope's NIRISS and NIRSpec instruments to probe the atmosphere of K2-18 b. It's an exoplanet already considered interesting due to its characteristics and its position in its planetary system's habitable zone. Spectral analyzes also suggest the possible presence of dimethyl sulfide (DMS), a compound considered a biomarker. These are discoveries that add to the previous ones regarding an exoplanet that led to the proposal of the Hycean class.

RESEARCHERS UNCOVER MOST COMPELLING CLUES OF EXTRATERRESTRIAL LIFE

In a groundbreaking study, researchers using the James Webb Space Telescope have identified compelling evidence suggesting the possibility of life on a distant exoplanet named K2-18 b, located 124 light-years away in the constellation Leo. This planet, 8.6 times more massive than Earth and 2.6 times its diameter, orbits within the habitable zone of a red dwarf star, where conditions may allow…

Livets signal-stoff funnet på planet utenfor vårt solsystem

Sannsynligheten for at planeten K2-18 b har liv anslås nå som 50/50 av astrofysiker og professor Nikku Madhusudhan ved Cambridge University. Det er de siste resultatene fra James Web Space Telescope (JWST) som antyder dette. Planeten K2-18 b er en av mange exoplaneter som har blitt undersøkt med teleskoper tidligere av NASA sitt Hubble Space teleskop og da utpekt som kandidat for videre studier…

Un articolo accettato per la pubblicazione sulla rivista 'The Astrophysical Journal Letters' riporta i risultati di uno studio dell'esopiane

Un articolo accettato per la pubblicazione sulla rivista "The Astrophysical Journal Letters" riporta i risultati di uno studio dell'esopianeta K2-18 b, inclusa la scoperta di composti di carbonio tra cui anche metano nella sua atmosfera. Un team di ricercatori guidato da Nikku Madhusudhan dell'Università britannica di Cambridge ha usato osservazioni condotte con gli strumenti NIRISS e NIRSpec del telescopio spaziale James Webb per sondare l'atmosfera di K2-18 b. Si tratta di un esopianeta già considerato interessante per le sue caratteristiche e la sua posizione nell'area abitabile del suo sistema planetario. Le analisi spettrali suggeriscono anche la possibile presenza di dimetil solfuro, un composto considerato un biomarcatore. Sono scoperte che si aggiungono alle precedenti riguardanti un esopianeta che ha portato a proporre la classe degli Hycean.
