As of today, ADS shows that ASCL entries have over 20K citations. Citations are not a perfect metric, but they do show ASCL is being used & is useful for citing software, thereby allowing code authors to get credit for the computational methods they contribute to the field, w00t! 🔭

of the Astropy project’s community. These packages are expressing an interest in Astropy’s goals of improving reuse, interoperability, and interface standards for Python astronomy and astrophysics packages. This metapackage installs all affiliated packages. 2/2

Random Debian Astro package of the week is python3-astropy-affiliated. A major part of the Astropy project is the concept of “Affiliated Packages”. An affiliated package is an astronomy-related Python package that is not part of the astropy core package, but has requested to be included as part 1/2⤵

I'm far from being an expert in this, but I licence anything I write, even though almost all of it is for personal use only. The Free Software Foundation, who are experts in this field, are a super source for information. www.fsf.org

🔭 Astro folks, I'm looking for a good link for a code that's been in ASCL for a while; existing link now fails. Author is deceased (alas); I have not found a replacement link. ASCL's archive does, however, have the code & a copy of the code website. We don't want to violate copyright, but...

Hey American astronomers! Did you know you can apply for European Research Council grants while in the US and, were to bring an ERC to University College Cork, you would *automatically* get a permanent position!? ERC starting grants (2-7 yrs post PhD) are €1.5M for 4 yrs with. ~10% success rate! 🔭

Did you get your Astronomy Conference BINGO card? Are you making progress on it? #AAS245

Come to the #AAS245 town hall today to discuss the ethical and other challenges that we face in using AI in astronomy! 12.45pm in National Harbor 2. (Below is what you get from ChatGPT when you ask for an optimistic and then a pessimistic view of astronomy and AI.) 🔭

Time for the NSF Town Hall at #AAS245 NSF is 75 years old now. 75 years of discovery and innovation. Chris Smith, interim director, is opening the session. First large national effort:

Check out our coverage of Day 1 of #AAS245 ! ✨🔭 astrobites.org/2025/01/14/a...

Press conference for supernovae and massive stars will start in a few minutes. Five presenters: David Coulter (STScI): JWST discovery of a distant supernova linked to a massive progenitor in the early universe #AAS245

ASCL is at #AAS245 in National Harbor in the great state of Maryland. Currently in the NASA Town Hall and blinking back tears as the absence of so many who live in California is acknowledged.

Damn, Sverre Aarseth (dynamists and developer of the NBODY series of codes for almost 60 years) passed away a couple of weeks ago. He is an absolute legend in the field, developing and publicly releasing software long before the concept of "open source" existed (paraphrasing Simon Portegies Zwart).

Sverre Aarseth, a great influence on open astro software, has died. ascl.net/wordpress/20...

Quick stats on this last day of 2024 Entries added in 2024: 266 Total entries: 3578 Citations to ASCL entries: 17700 Percentage of entries cited: 42% (Citation stats from the incomparable @adsabs) And a couple of figures, too. 🙂 Happy new year to all, and to all, #openscience!
