Free organic volatiles and IOM thermal degradation products liberated by flash heating to ~610 °C of Bennu samples. Shown are total ion chromatograms obtained by pyrolysis analysis of Bennu (A–D)

Saturn’s moon Mimas, imaged by the Cassini spacecraft. A new study shows how such small ice moons could sustain a liquid ocean beneath an icy shell, and how that could

Close-up view of bacterial communities thriving at the vent site. The distance between the two green laser points is 9 cm, providing a scale for the dense microbial structures visible
