One hour stacked HATPI subtracted images of 3I/ATLAS from each of the nights on which 3I/ATLAS is formally detected with 3σ confidence in the full night binned light curve (nights

Normalized number of monomers and dimers as a function of the temperature and reaction time. Three states are identified: thermodynamic compression, combinatorial explosion, and kinetic compression. In addition, at very

Viking 2 Image of Mars Utopian Plain in 1976 – larger image — NASA How do scientists maintain their research programs in the face of not finding anything? Continual failure

Overview and performance of the LUMOS framework for biogenicity assessment. a, The LUMOS (Life Unveiled using Molecular Orbital Signatures) framework integrates amino acid abundance measurements with quantum chemical descriptors to

Morphological comparison of the Apex Chert and the Strelley Pool Formation microfossils with EM-P. Images (A-D) are TEM images of EM-P cells forming intracellular vesicles (ICVs) and intracellular daughter cells.

Subsurface ice final depth interpolated map for latitudes 40-55 North, assuming ice was emplaced 630 kyr ago for 1% dust fraction scenario and no lag layer porosity. The red line

Conceptual model illustrating a possible evolutionary trajectory of ATP-generating enzymes. Under prebiotic conditions with a limited amino acid repertoire, kinase-like proteins resembling Arc1-12KR or Arc1-11K may have generated ATP through

Illustration of liposome protection from UV. The top panel shows a drawing of the crater. The top- and sideview photographs show the intensity distribution of the blue color after UV

An artist’s illustration depicts the astrosphere in more detail, including a bow shock in blue — akin to a sonic boom in front of a supersonic plane — that is
