Joint posterior constraints on the surface partial pressure of key atmospheric absorbers for atmospheric scenarios similar to solar system terrestrials, with N2 as the background gas. The color shadings correspond

Sulfuric acid phase diagram. The pressure in atm (y-axis) vs. temperature in K (x-axis). The large purple shaded region represents the theoretical liquid-phase boundary for 98% w/w concentrated sulfuric acid

Star: HD127423, Spectral Type:G0V, Observation Date/Time: 2013-06-01, 04:16:19.375. Top panel: reduced spectrum. Bottom panel: subsection of the corresponding CCD image for this wavelength range. — astro-ph.IM We examined archived observations

Reflectance spectrum of 3I/ATLAS. Also, Mahlke templates of S-, D- and Z-type asteroids are shown (Mahlke et al. 2022). Shaded areas indicate the standard deviations of the template spectra. —

The upper panel illustrates the mass loss processes and potential formation of graphite in sub-Neptune atmospheres within the graphitestability regime. The lower panel presents the atmospheric compositions calculated from the

Planet occurrence rates as a function of stellar temperature for short-period (P = 1 − 40 days) super-Earths (green squares) and sub-Neptunes (blue circles). A power law was fit to

Searching for extraterrestrial life and supporting human life in space are traditionally regarded as separate challenges. However, there are significant benefits to an approach that treats them as different aspects
