The spatial coverage of our study of L 1688A, with the underlying extinction map being computed using 2MASS catalog (Cutri et al. 2003) adopting the NICE technique from Lada et al. (1994). The color bar shows the extinction range. The red square encloses the area of the W band observations covering a field of 20′ × 20′ corresponding to a linear scale of 0.8 pc. -- astro-ph.SR

Water-Bearing Objects in the Core of the Rho Ophiuchi Cloud Complex

The spectral decomposition of the Reference case retrieval of WASP-166b with the absorption contributions of the key atmospheric constituents shown. Spectra are plotted with resolution R = 100 for clarity. The combined forward model, shown as a heavy black line, is the median Reference retrieval result (see Table 5). The colored lines correspond to the individual opacity/absorption contributions (including Rayleigh scattering and collision absorption) of the various constituent molecules and clouds at specific wavelengths. (H2S is plotted but is not distinguishable from the bulk species line.) The transmission spectrum is dominated by contributions from H2O (15.2σ), and CO2 (14.7σ). The more subtle effects of NH3 (2.3σ) may be apparent at ∼ 2.3 µm, and possibly at ∼ 3.9 µm. The effects of the cloud deck (flat purple line at transit depth of ∼ 0.274 x10−2 ) are apparent in clipping the troughs of the water features from 0.85 to 1.7 µm -- astro-ph.EP

Wiping down hardware is part of the strategy to limit the number of Earth microbes going to the Red Planet for NASA's Mars 2020 Perseverance mission. This cleaning takes place in the Spacecraft Assembly Facility clean room at NASA's Jet Propulsion Laboratory in Southern California. -- NASA JPL larger image
