If you are user of the Python package Pandas, I cannot recommend switching to Polars highly enough. #astrocode
I'm doing some groupbys for some plots, and a complicated set of string & numerical operations on *25 million rows* takes just 3 seconds on my laptop.
The Pandas equivalent: 2+ minutes. 🤯

Can astronomical imaging be more sensitive, with no additional observations?
Guo et al. apply machine learning to the co-addition (stacking) of multiple exposures. For stacks of 8 JWST NIRCam exposures, the detection limit improves by 1 magnitude. ☄️🔭 #astrocode
