(A) Sampling information and morphological characteristics of 11 deep-sea species. These samples were captured from depths ranging between 1,218 and 7,730 m, spanning locations from the Mariana Trench to the Middle Indian Ocean by the manned submersible “Shenhai Yongshi (Deep-Sea Warrior)” and the manned submersible “Fendouzhe (Striver)” as well as the remotely operated vehicle (ROV) “TIAN YA (Skyline)” during our expeditions aboard the mothership TAN SUO YI HAO (exploration I) and TAN SUO ER HAO (exploration II).

Molecular complexity growth rate per bond count between PubChem and COCONUT 2.0 molecules. Mean (solid line) and standard deviation (shaded area) of complexity scores per bond count between PubChem molecules in blue (n ≈ 100,000,000) and COCONUT 2.0 molecules in green (n ≈ 525,000) for a, Bertz, b, Böttcher, and c, MA. d, The databases had similar distribution of bond counts in their molecules. -- cs.LG

25.3 µm map of the NGC 7538 region from SOFIA/Faint Object infraRed Camera (FORCAST; Herter et al. 2013) archival data (Cycle 1 Program 0034, PI A. G. G. M. Tielens). Our target and brightest source, IRS 1, is at the centre with offset 0′′, 0′′ corresponding to α(J2000) = 23:13:45.37, δ(J2000) = +61:28:10.5. The positions of IRS 1 and the dimmer sources (IRS 2, IRS 3, IRS 1E, and IRS 1SE) are given by Sandell et al. (2020). In solid green is the 8.7′′×3.2′′ EXES slit from this work’s 23.9 µm setting (Table A1), and in dashed blue the 14′′ and 18′′ JCMT beams (van der Tak et al. 2000; Bisschop et al. 2007) whose CH3OH results we will use for a comparison (Section 5.1). au scale uses a distance of 2.65 kpc (Moscadelli et al. 2009). Note the logarithmic scale for the flux, which exaggerates the brightness of the non-IRS 1 sources. -- astro-ph.GA

Examples of training reflection spectra for Earth-like exoplanets in the Archean (left), Proterozoic (center), and Modern (right) eras, observed with LUVOIR-B (top row) and Habex/SS (bottom row). Colored lines represent the total radiance 𝐴(𝜆), while points with error bars correspond to 𝐴noisy (𝜆) as defined by Equation 13. -- astro-ph.EP

The region in which dark matter impacts may leave detectable surface features on Ganymede. Gray regions correspond to existing constraints [33, 35, 37]. The light purple region is the region in which the dark matter has sufficient initial energy to penetrate through the 12 km conductive ice layer on Ganymede’s surface. The darker purple region corresponds to when the dark matter penetrates the entirety of Ganymede, leaving both an entrance and exit wound. Rough estimates for the approximate number of craters and crater radius from Eqs. 1 and 13 are provided on the top and right axes respectively, rounded to one significant figure for readability. -- astro-ph.EP
