NASA’s Mars rover Curiosity acquired this image using its Mast Camera (Mastcam); it shows the “Nevado Sajama” drill site from November, right next to the location of this weekend’s drill.

A planet with a magma ocean — Grok via Astrobiology.com Sub-Neptunes with hydrogen-rich envelopes are expected to sustain long-lived magma oceans that continuously exchange volatiles with their overlying atmospheres. Capturing

Infrared spectrum of Ser-emb7 after continuum removal and peak fitting. The original spectrum (dark gray) is fit with color-coded peaks, which are identified in the legend, that sum to an

Comparison of host star masses and metallicities of N ≥3 categories of exoplanet systems (black points), compared with two of our potential source populations: all exoplanet hosts with jupiters (red)

Transmission spectra of solid methanol and its five deuterated isotopologues at 10 K. The region between 650 to 590 cm−1 (15.4 to 16.9 µm), affected by increased noise from the

Potential energy profiles for the three abstraction channels in the CH3CH2OH + F reaction. All energies are ZPVE corrected. — astro-ph.GA Alcohols and aldehydes represent two key classes of interstellar

Step-by-step procedure of the transit encapsulation in the TIC 020209388 light curve. The X-axis and Y-axis specify time in days and normalized flux, respectively. Top panel: 1 — simulated transit

The top row (A to C) shows longitudinally averaged cross sections of ventilation age, where younger ventilation ages represent water parcels that have more recently interacted with the ocean-atmosphere interface.

Thionylimide (HNSO) — astro-ph.GA We investigate the formation of the recently detected HNSO molecule using quantum chemical calculations on ices and astrochemical models in tandem. Our results indicate that HNSO
