The surface temperature at the centre of this alien ocean could even reach 20 degrees Celsius.<br>The planet is rarely observable (about eight times a year), which makes it difficult to study in depth, but if the Canadian researchers' intuition is correct, you can be sure that we will be hearing more about Lhs 1140 b!<\/p>","protected":false},"excerpt":{"rendered":"<p>Le ultime osservazioni del telescopio James Webb hanno aperto un nuovo scenario per il gi\u00e0 noto esopianeta Lhs 1140 b, tra i pi\u00f9 promettenti nella zona abitabile della sua stella, una nana rossa di bassa massa, grande circa un quinto del Sole, potenzialmente in grado di ospitare un\u2019atmosfera e persino un oceano di acqua liquida.
