A confusing statement. NASA's proposed 2025 budget was 25.4 billion dollars. If this ESA budget was annual, it would be similar. But I think this is for 3 years. ☹️
22.1 billion euros subscribed.
A record.
A first.
And a clear message that Europe is serious about space and that @esa.int is the agency it trusts to deliver.
A historic Ministerial. A united Europe. A stronger ESA.

I'd like to talk to people organizing VR field trips for schools, seniors or other groups. Any suggestions?

It would be fun to work out what the sky would have looked like 66 million years ago, on the day before the asteroid wiped out the non-avian dinosaurs. I think quite different. Has anyone already done that?
It's Friday, and apparently bluesky is ready for this fun revelation:
Dinosaurs lived on the other side the Galaxy.

Clever phrasing. When I was growing up in Canada, the country to our south was the "United States".
"America" was the continents.

Well OK, I can sort of understand the excitement of being able to visit real environments in VR, but the astronomy worlds I can create in VR are way more interesting than my home office.

I've done a revised version of my O-type star poster which uses Bailer-Jones distances where available. This eliminated 7 stars that are now further than 1250 pc but added 11 more.

I don't know how I missed this but I see that the IAU Working Group on Star Names (@iau-wgsn.bsky.social) is still active and has released a number of new names this year. As a cartographer of course I love the idea of giving more names to visible stars that I can use on maps!

Another example of how my favourite VR game, Walkabout Mini Golf, is evolving into a more general social space. As well as some of the most inventive and beautifully realized locations in VR, it has treasure hunts, slingshot games, meeting areas and now chess.

Following up on my O-type star map, I found 11 additional stars that have Bailer-Jones distances less than 1250 parsecs, O-type spectra in SIMBAD but do not *appear* to be in the O-type catalog I used for the map. Perhaps because they have separate Gaia IDs but the star system is already on the map?

A new 3D map of interstellar dust with Gaia! 🌌
A new study, led by Marie Barbillon, exploited the spectroscopic parametriser from Gaia DR3 to build a high-resolution extinction map! It extends up to 4 kpc from the Sun, with a finer version focused on the Local Bubble area.

Interesting discussion with @astrochara.bsky.social. Quoting it here for people interested in galactic structure.
Indeed…I wonder if it could be that the distribution of OB stars within even a continuous spiral arm are naturally patchy, and that’s why we’re seeing them as disconnected structures here.

If you have ever wondered what the interstellar medium looks like in 3D, visit the Star Central VR world and walk around the 3D Local Interstellar Medium display, which shows dust clouds, ionized hydrogen, hot star density and star clusters out to 500 parsecs.

I've continued to add improvements to the O-type star map. Just added a line to highlight the interarm gap. The spiral structure is not very clear in Gaia but at least there is a clear gap between the local and inner galaxy.

I've created a new map of all known O-type stars out to 1250 parsecs. These extremely rare and ultra hot stars play an important role in ionizing hydrogen gas and reshaping dust clouds across the Milky Way.

![[Scene is a kitchen - a middle aged woman called JANET is boiling peas at the stove. A younger more colourfully dressed woman named LIZ approached her.]

Ugh...

I am so bored of cooking peas!

Have you tried...
AI peas?
JANET:
AI peas?

They're peas with AI!

Why not take your peas to the next level with Al Peas' new Al tools to power your peas?
[Show a techno diagram of a pea with a label reading 'AI' pointing to a random zone in it]
LIZ:
Each pea has Al in a way we haven't quite worked out yet but it's fine
[Show Janet and Liz now in a Matrix-style world of peas]
LIZ:
With Al peas you can supercharge productivity and make AI work for your peas!
JANET:
What
LIZ:
Shut up
LIZ:
Our game-changing Pea-Al gives you the freedom to unlock the potential of the power of the future of your peas workflow
From opening the bag of peas
to boiling the peas
to eating the peas
To spending millions on adding Al to the peas and then having to work out what that even means.
