The strength of indirect detection signals from an Earth-like exoplanet as a function of stellar effective temperature. Bands encompassing main sequence spectral classes A through M color coded by temperature

Combined fit results for K2-79 b. Transit fit to the light curve data from K2 long cadence (first row left), TESS long cadence (first row centre), and CHEOPS (first row

Top: MIRI-MRS spectra of VHS 1256 b, with the spectral regions used for molecular detection highlighted for each species. Bottom: Corresponding Exo-REM molecular templates for the detected molecules, showing both

Co-added observed spectra of 3I with best-fit model Observed and modelled 13CN centred (left) and 15CN-centred (right) line profiles. The shaded region represents the uncertainty of the profile resulting from

Spectrally integrated line flux maps for 3I/ATLAS observed using JWST NIRSpec: (a) H2O at 2.7 µm, (b) CO2 at 4.3 µm, (c) CO at 4.7 µm. Image axes are aligned

Graphical Abstract — NASA Biofilms are communities of microorganisms that stick to one another and also adhere to a nearby surface. They are intricately associated with life on Earth, enabling
