Namen van de NameExoWorlds 2022 campagne bekend

Culturen over de hele wereld hebben lang verbanden gelegd met objecten in de natuurlijke wereld door ze namen te geven in hun moedertaal. Veel beschavingen hebben hun eigen verhalen, mythologieën en culturele contexten ontwikkeld rond lichtvlekjes in de hemel erboven.

One of our #Podcast segments is looking at the #IAU #constellation charts & seeing if our first impressions match the constellation iconography.

In Season 1: #Zodiac, we found these ones most convincing 👍 : ♊ ♌ ♍ ♎

And these ones complete and utter mysteries 🤔: ♑ ♓ ♋ ♐ ♈

What's your ranking?? Here are the charts: https://www.iau.org/public/themes/constellations/

The formerly named #HubbleLaw (not really a physical law, just a good approximation on some scales) is now the #HubbleLemaîtreLaw, thanks to an #IAU decision based on the evidence.

Should the #HertzsprungRussellDiagram [1] be renamed the #HertzsprungRussellMauryDiagram [2][3] to recognise Antonia Maury's key contributions [4]?

A mountain near the Moon's south pole has been named for a NASA mathematician who helped design trajectories and track Earth-orbital satellites and the Apollo spacecraft.

#Science 📆 27 Feb 2023 The Committee on the Peaceful Uses of #OuterSpace (#COPUOS) drafted #guidelines to limit the creation of #SpaceDebris which have been incorporated into national #laws in more than 45 countries, including most of the major #spacefaring nations. (#China 🇨🇳 has yet to adopt them.)
#Satellite 🛰️ trails & radio interference : The #IAU proposed to set up an #expert group to study the issue for 3 years before presenting guidelines. “We need solutions that are feasible and acceptable to those who #operate the #satellites” https://www.science.org/content/article/astronomers-stumble-diplomatic-push-protect-night-sky

Word from this weekend’s 2023 Taipei Ultramarathon that Joasia “Jo”Zakrzewski will set a new #IAU 48hr women’s world record shortly. As of noon today local time (45hrs elapsed), she had 391.369km & is on track to pass Patrycja Bereznowska’s existing 48hr WR of 403.320km.

It would be nice if they could go into the Gazetteer of Planetary Nomenclature, but terrestrial place names are outside the scope of the #IAU Working Group for Planetary System Nomenclature

A poster that I presented at the IAU Symposium 277 "Tracing the ancestry of galaxies (on the land of our ancestors)", back in 2010 in Ouagadougou, Burkina Faso 🇧🇫

It's in front of that very poster that I met Prof. R. Brent Tully, discussed potential application of this software in the field of Cosmography, and started working on Cosmicflows soon after!

Recently I've changed my mind and now prefer the definition of a #planet as a "Round Thing that Goes Around the Sun" more than the #IAU Definition of "Round Thing That Goes Around The Sun and Has Cleared Its Orbit".

Mostly because I heard on the #AstronomyCast podcast that some solar systems could have earth or even gas giant sized worlds that circle in distant orbits but haven't managed to clear their orbits. It seems unfair to define these big boys as "Dwarf Planets" like Pluto or Ceres.

Entre la lista de 20 exoplanetas a ser observados por el #WebbTelescope que la #IAU propone renombrar en esta edición del Name ExoWorlds se encuentra Gliese 486 b, descubierto en 2021 gracias en gran parte al consorcio
#CARMENES. Gliese 486 b se ha convertido en uno de los exoplanetas telúricos mejor estudiados gracias a las recientes investigaciones realizadas desde España. Por ello, esta iniciativa propone renombrar a este exoplaneta y su estrella anfitriona como "Su" y "Gar", respectivamente

BlueWalker 3: Astronomen besorgt wegen besonders hellem Riesensatelliten

Der Kommunikationssatellit BlueWalker 3 gehört jetzt zu den hellsten Objekten am Nachthimmel. Die IAU ist besorgt und fürchtet Folgen für die Radioastronomie.

IAU Centre for Protection of the Sky #IAU-CPS now has an update on #BlueWalker3 #satcon: the 64 m^2 sheet of antenna of the prototype makes it one of the brightest objects in the night sky https://www.iau.org/news/pressreleases/detail/iau2211/

What is this #podcast about?
All things #constellations! Each month we explore the #astronomy and #myths of one of the #IAU constellations. We talk about cool #space stuff (with a bias toward #blackholes & #exoplanets) as well as analyzing & retelling the myths of the night sky (a segment we like to call ret-con…stellations)

Our first season is underway & focused on the Zodiac constellations! Have a listen here: https://starrytimepodcast.com/episodes

Me lo appunto anche per il sottoscritto!

"The International Astronomical Union considers the consequences of satellite constellations worrisome. They will have a negative impact on the progress of ground-based astronomy, radio, optical and infrared, and will require diverting human and financial resources from basic research to studying and implementing mitigating measures."
