TESS 2-min cadence photometry of TOI-237 obtained with the TESS automatic aperture. Each of the panels shows the Sectors 2, 29, and 69, respectively. TOI-237 b is highlighted in blue,

The calculation flow in our model. We model the dynamics of gas and dust containing volatile ices and semi-volatile salts to calculate the C, O, N, and S abundances in

Analyzing a precious bit of space dust no bigger than a teaspoon, the Penn State team used custom instruments capable of measuring isotopes, slight variations in the mass of atoms.

The experimental pipeline, from design to characterization, of peptides comprising the Xeno 1 and Xeno 2 amino acid alphabets. Design begins with a library of commercially available amino acids. The

Known potentially-rocky exoplanets within 20 pc. The vast majority of the closest planets are non-transiting and their atmospheres cannot be characterized with currently-available techniques. Data from the NASA Exoplanet Archive,

The best-fit PICASO retrieval temperature-pressure (TP) profile is plotted as a solid blue line with the temperature-pressure knots indicated in solid blue circles. The light blue shaded region indicates the

GC content, total number and their frequencies of PQS in H. volcanii genome. (A) Schematic presentation of a G-quartet (left) and a G-quadruplex (right). (B) Total PQS counts, percentage of

Illustration of the electrodynamic interaction between Enceladus and Saturn. The primary Alfvén wing is shown in blue, and the reflected Alfvén wings in magenta. The arrow indicates the corotation direction
