8 de janeiro agora é o dia da vitória da democracia 🇧🇷✊

É pra lembrar o que aconteceu, defender o Estado Democrático de Direito e garantir que nunca mais se repita. Democracia é voto, é Constituição e é respeito.

I've put up one of the most ambitious (and lengthy) articles I've written on the Milky Way. The timing works out well because this year is the 75th anniversary of the detection of the 21 cm line, one of the events that started the Golden Age of galactic cartography.

How Gaia revealed the Milky Way
For more than a decade, Gaia mapped the brightness, motion, and composition of 2 billion stars. Its legacy is just beginning.

Latin had six noun cases, but in all Romance languages except Romanian, nouns and adjectives only have one singular form and one plural form left. What happened?

This extra large infographic tells you how the Latin case system collapsed – and why it's the accusative case that lives on in Romance.

Just like every year, a friendly PSA:

“Feliz ano nuevo” means “happy new anus.”

“Feliz año nuevo” means “happy new year.”

Wishing folks either one is nice, but make sure you’re using the one you mean.

After reading through references in more recent papers, it looks like this 1954 paper is the origin of the term "Sagittarius arm" (and possibly "Orion arm" as well).

As far as I can tell, the first "race track" schematic model of the Milky Way appeared in a Soviet paper in 1964. Here's an English translation done in 1965: ui.adsabs.harvard.edu/abs/1965SvA....

Played it twice now. First time, we realized at the end that we were doing it wrong which is why it didn't make sense. Second time, we got out the wine & reread the instructions & played it correctly & it was really fun! (even though we didn't "solve" the #Voynich Manuscript...maybe next time!) 🧵

Here's a preview of my next Gaia DR4 article scheduled for January. What could Gaia DR4 tell us about the inner galaxy?

The first image is figure 8 from Kwee 1954, which may be the first map ever published for the inner galaxy.(ui.adsabs.harvard.edu/abs/1954BAN....)

Uses old galactic longitude.
