The search for traces of life can be based on the detection of specific signatures produced by microorganisms on sedimentary rocks. Microbially induced sedimentary structures (MISSs) develop under specific physicochemical

(A) Spectrally integrated flux map for CO on 2024 March 8. Contour intervals are in 1σ increments of the rms noise, with the lowest contour being 3σ. Sizes and orientations

Cuts of the 3D magnetic volume of the fossil in three different heights: The blue/red colour indicates the in-plane component of the magnetisation, with magnetic moments swirling around a central

(a) Normalized age distributions p(τ | ) for single stars, binned in and smoothed using Gaussian filtering. Each vertical slice is normalized by its peak value. The blue line

The left panel shows a zoom of the GA and ethanol emission maps toward B0, B1 and B2 respectively, integrated over the velocity range km s−1 . The
