Temporal evolution of atmospheric mass loss in response to stellar flares of different energies. The ratio of the instantaneous mass loss rate to the quiescent mass loss rate is shown

Surface of Ryugu, taken at night by Hyabusa-2’s Mobile Asteroid Surface Scout (MASCOT) camera MASCOT/DLR/JAXA Carbonaceous chondrite (CC) meteorites are fragments of planetesimals that hold clues about the early solar

This image shows a wide-field view of part of the Taurus Molecular Cloud, about 450 light-years from Earth. Its relative closeness makes it an ideal place to study the formation

Baade/MagE spectrum of TOI-2407 compared to the M2 SDSS template from Bochanski et al. (2007, magenta line). Data are normalized at 7400 Å, and key spectral features across the 4300–8100

Different types of coastal microbial mats were documented: Lift-off mats from Sisal (B), Pustular (C) and flat (D) microbial mats from Progreso, and flat mats from Ría Lagartos (E). —

Routes to α-keto acids from amino acids. a) The conversion of an α-amino acid to an α-keto acid via transamination requires an additional α-keto acid; however, b) the β-elimination of
