Overview of the ibSLS database content. a. Numbers of samples available in the current ibSLS, categorized by assay type (outer ring) and mission (inner ring), with sample counts indicated in

Tiny life forms tucked into debris from an asteroid hit could catapult to other planets – including Earth – and survive, a new Johns Hopkins University study finds. The work

This geyser exhibits irregular behavior, sometimes erupting regularly for months, and then ceasing altogether. Echinus is a rare acidic geyser, with a mixed water rich in both sulfate and chloride.

Representation of the two main frameworks used to quantify molecular complexity: (a) graph-theoretic and b) information-theoretic approaches. Tryptophan is depicted as both a graph representation and a molecular structure, illustrating

Aerosol deposition on the surface following 5 Mars years of 2.5 l/s release and 15 Mars years of shutoff. The distribution is comparatively uniform, with more deposition at low elevations,

Occurrence of bd-type oxygen reductase in a dated tree of life. Branches in the dated tree of life obtained from Mahendrarajah et al. are colored according to the
