GEMINI v1.17 Release Notes

The Gemini release notes come with

"Note that the testing with Community PyRAF has highlighted issues with PyRAF itself when run with 64-bit binaries"
iraf.noirlab.edu/gemini_v17_r...

However, no issue was raised for this in the PyRAF repository.
May I ask to open a bug so that it can be fixed?

Dwarf galaxies tip the scales in favor of dark matter over modified gravity An international team of researchers led by the Leibniz Institute for Astrophysics Potsdam (AIP) has shed light on a decades-long debate about why galaxies spin faster than expected—and whether this behavior is caused by invisible dark matter or by a collapse of gravity on cosmic scales.

Analysis of stellar velocities in faint dwarf galaxies indicates their internal dynamics are better explained by dark matter models than by modified gravity theories such as MOND. doi.org/g977ff

We are mapping the stars on the Magellanic Clouds to uncover their formation and interaction history.

The 1001MC survey will collect spectra for around 500,000 stars, measureing velocities ane elemental abundances.

#Belarus The regime must reveal information about Mikalai Statkevich. Where is he? How is his health? Why was he released and was later driven away? This is unacceptable and very worrying that the regime is hiding him. Is he alive?

#Belarus Excruciating. This is reportedly opposition leader Mikalai Statkevich in the neutral zone between Belarus and Lithuania. Freed after over five years in prison, he is protesting his de facto deportation. The regime must stop expelling Belarusian citizens from their own country!

This is a top-down image of the front of a new instrument for ESO’s telescopes. At its outer edges is a ring of metal, within which sits a hexagonal structure made of thousands of fibres that are standing upright. From this angle, each one looks like a single point, and some of the fibres have been moved closer together so that they form a pattern within the hexagon. For this image, the pattern is the shape of a large number four.

It depends on what you mean with "standard astronomical software". Most Open Source software is portable. IRAF is there, DS9 is, most Python packages (Astropy&Co) are, … ESO-MIDAS could work but may need complilation; same for SourceExtractor. TOPCAT should just work as well as other Java packages.
