Best-fit model to an empirical transmission spectrum of the cloudless Earth in units of scale height, H (adapted from (40)). Different colors indicate the contributions from various molecules. Despite its

Major steps in the disk detection process on two cubes: (far left) an unaltered cube; (center left) edge pixels identified using Canny edge detection – some pixels along terrain boundaries

Schematic of the layered systems: CO2 deposited on (a) bare gold (Au), (b) water ice on gold, (c) a silicate film on gold, and (d) ice on a silicate film

Envelope H2O mass fraction as a function of semi-major axis. The same dataset as in Figure 1 is shown. The left panel shows planets that predominantly formed inside the water

The 134Xe/132Xe versus 136Xe/132Xe diagram showing the composition of Tatahouine (#13349) and Shalka (#6766 C) measured at different heating steps, including those of Michel & Eugster (1994) and Eugster &

This diagram shows the trajectory of interstellar comet 3I/ATLAS as it passes through the solar system. It will make its closest approach to the Sun in October. NASA/JPL-Caltech On July

NASA’s Curiosity rover captured this photo as it ascended the Martian mountain Mt. Sharp. A study proposes a new explanation for why Mars is a barren desert today, despite having

Schematic of the post-impact scenario for prebiotic atmospheres (Genda et al. 2017; Zahnle et al. 2020; Wogan et al. 2023). In this scenario, reducing power is delivered to the surface-atmosphere
