Please spread the word! In addition to becoming an important part of the MESA project, the person in this role would have opportunities to collaborate on scientific software across CCA, which has a vibrant, interactive community of scientists and code developers.

The year is 2026. Venezuela faces the United States in the WBC, as the matchup takes on extra significance after the United States kidnapped the Venezuelan president, which is at least the 15th or 16th-most batshit story of the last couple months.

Here come the cold giants! A combination of RV and astrometry reveals several "Jupiter analogues", among them one planet (around HIP 39330, a G5V star, ca. 100 ly away) that matches Jupiter quite nicely: a=5.05 au, e=0.078, M=1.67 M_jup. If only we could quickly check for terrestrial planets inside!

pynucastro now supports the StarLib reaction rate library, which includes uncertainties on rates. With pynucastro, you can now create different realizations of the rates, sampling the uncertainties, to look to see how nucleosynthesis is affected:
