This title covers breaking news (relatively) and short pieces regarding the AAS (American Astronomical Society), versus, say, Planetary Science Journal or Astrophysical Journal. In the January RNAAS… Read More »Note, Paper: AAS’ AIs …? On AAs?
For what it’s worth, the December issue of Nature Astronomy is a special one on Ryugu. Of course, we’re in the digital era, so the notion of an “issue” is handwavey- most of the works in it were already put… Read More »Tout, Papers: Special Nat. Astron. Issue
