This figure presents a modern tree of Life, highlighting eukaryotes (organisms with complex cells) based on genome-scale analyses from Valt et al. (2025). The newly identified and ancient supergroup Disparia

Aggregated three-dimensional py–GC–MS data for samples in each of our nine categories: modern animals; modern plants (non-photosynthetic); modern plants (photosynthetic); fossil microbes (photosynthetic); fossil coal, wood, oil shale; fossil animals;

The recovery probability (successful AltaiPony detection) of injected flares in the TESS light curves of GJ 1132 (top left), TOI-2445 (top right), TRAPPIST-1 (bottom left) and the average of recovered

Suppression in logarithmic units (diffraction intensity at the telescope aperture ∥f ∥ P ∥ 2 ) is shown for the HWO 60 m starshade with 16 petals at a wavelength

The diversity of unicellular eukaryotes covered in the study, with their nucleus (blue) and microtubule cytoskeleton (magenta) stained. These organisms are so distantly related to each other as they are

The mass and radius of our two models for GJ 12 b (circular and eccentric orbits) compared to various composition models from L. Zeng et al. (2019), as well as

Comparison of synthetic and observed solar G-band intensity at wavelength 4306.8±15 Å at different positions across the solar disc (different rows). The synthetic G-band has been convolved with the SST
