Earth-like Exoplanets Are Unlikely To Be Another ‘Pale Blue Dot’
When searching for Earth-like worlds around other stars, instead of looking for the ‘pale blue dot’ described by Carl Sagan, new research suggests that a hunt for dry, cold ‘pale […]

Star Light Simulator Illuminates The Search For Life Around The Milky Way’s Most Common Stars
Italian researchers have demonstrated experimentally for the first time that microorganisms can photosynthesise using the infrared-dominated light emitted by the most common type of star in the Milky Way.

The Kinematics And Excitation Of Infrared Wwater Vapor Emission From Planet-forming Disks: Results From Spectrally-resolved Surveys And Guidelines For JWST Spectra
This work presents water emission spectra at wavelengths covered by JWST (2.9-12.8 μm) as spectrally-resolved with high resolving powers (R = 30,000-100,000) using ground-based spectrographs.
