That means they can detect a wide range of heat signatures in the far-infrared spectrum without needing to be chilled—potentially transforming how we build night vision and heat-sensing devices.

And now, K2-18b is in the news once more, this time thanks to the discovery of hints that the atmosphere may contain stuff called dimethyl sulfide ... the stellar spectrum resulting from sunlight ...
