NASA's Webb captured a striking view of a cosmic dance of a pair of interacting galaxies nicknamed “the Penguin and the Egg" to mark its 2nd anniversary.
Data revealed that the interior of the exoplanet might be significantly hotter, and the core might be much more massive than what was estimated previously.
The exoplanet K2-18b’s atmosphere has signatures of carbon dioxide, methane and possibly dimethyl sulphide, which is not known to exist where life does not.
