(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

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

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
