The C++ library provides input/output, basic spatial operations such as conversion between spherical coordinates and HEALPix pixels, and also sophisticated spatial operations such as querying cones or polygons, as well as upsampling/downsampling, smoothing, and fast spherical harmonic

This package provides the static library and headers for the C++ language implementation of HEALPix.

Random #Debian Astro package of the week is libhealpix-cxx-dev. HEALPix is an acronym for Hierarchical Equal Area isoLatitude Pixelization of a sphere. As suggested in the name, this pixelization produces a subdivision of a spherical

This sounds very doom-ish but SciX works great for astro, I have made the switch entirely from ADS and haven't lost any function or speed. 🔭 (would be interested in hearing about usage in other fields)
Well this is worrying. NASA has maintained funding for ADS but not SciX (a broader database). In response, management is planning to *close* ADS in Feb 2026, forcing all users to switch to SciX. ☄️🔭

I'm happy to report that "Scenario 2" won't be necessary, as NASA has just communicated to us that SciX funding will continue in 2026 (albeit at a reduced level). Therefore, we will not be forcing astronomers to leave ADS, but rather develop a plan that allows a longer transition.
