Hot pictures for a hot afternoon 
Most of the images in my book, "111 Places in Space That You Must Not Miss", came from space agencies & observatories, as well as talented archive image processors & amateur astronomers, most released with CC licences.
But I made quite a few too, also processing archival data, from my JWST observations, or from my back garden.
I've made them all available with CC BY-SA licences here:

The northern summer solstice was at 02:42 UTC this morning.
As usual, the Sun did not care much

Just time for lunch today at the mothership, & good to see a couple of my former Science Directorate colleagues 
“So, hands up who thinks Mark’s new book is groovy?” 
Thank you very much to ESA Director General, Josef Aschbacher, for his enthusiastic endorsement of “111 Places in Space You Must Not Miss” at the Paris Air Show today, publication day 
(Truth be told, he was actually speaking after my talk & asking which of the kids in the audience would like to be an astronaut, but the picture taken by Karen O’Flaherty was too perfect not to use 
)
Gone but not forgotten
On behalf of XMM-Newton, Rosetta, Herschel, Planck, BepiColombo, JWST, & JUICE, thanks for the ride to space, #Ariane5 
As seen at the Paris Air Show at Le Bourget today.
Just passing through Mannheim, to connect to the TGV direct to Paris 
Will be going out to Le Bourget tomorrow to give a talk at the Paris Air Show.
It’s supposed to cover the science highlights from the roughly fifty space science missions ESA has built and/or collaborated on over the Agency’s half century history 
All in twenty five minutes 
Just two days now until my book, "111 Places in Space You Must Not Miss" is published in Europe 
As you might have guessed, there are 111 mini-chapters, each comprising around 350 words of text & a full-page image describing somewhere interesting in space 
Here are all 111 of those images ... well, at least a central 20 pixel wide strip of each one
Europe: 19 Jun
UK: 21 Jul
US: 2 Sep

The International Space Science Institute in Bern is looking for a director. Can recommend as a really nice institute hosting good meetings in a beautiful city.
Millions of degrees hot off the press – first results from ESA's PROBA-3 mission, using two spacecraft separated by 150 metres to create artificial solar eclipses.
This makes it possible to trace the solar corona close to the surface of the Sun on a routine basis, not just during actual eclipses.
Congratulations to the PROBA-3 team

Apropos space missions studying the Sun's poles, here's a little something from 6 October 1990.
The deployment of the ESA/NASA Ulysses mission from space shuttle Discovery as part of STS-41.
The spacecraft is at top left of the IUS/PAM-S combo, which powered it towards Jupiter.
There it used a big gravity assist to get out of the ecliptic & orbit over the north & south poles of the Sun.

Currently doing battle with a truculent million year old baby protostar below the belt of Orion, moving behind clouds some eighty million au away 
As a brief distraction, here’s a several billion year old grown-up star just one au away, playing with the water and ice in the atmosphere of one of its planets
In just under a fortnight, on 19 June, my book "111 Places in Space That You Must Not Miss", will be published by Emons in Germany, followed by the UK on 21 July & the US on 2 September 
It's a tour guide of interesting places in our Solar System, the Milky Way, & Deep Space beyond, & describes what you'd find & learn if you were able to visit them
Here's a preview of the cover & a few chapters – it's available to order in all the usual places
A nice cross-over this evening: I gave a talk about the technology & science of JWST to the 25th European Light Microscopy Initiative (ELMI) conference, held at the European Molecular Biology Laboratory (@EMBLEvents) in Heidelberg 
Thanks to the very kind audience, to Timo Zimmerman & Aline Schnieder of EMBL for the invitation & organisation, & to the folks from Teledyne who made the JWST near-IR detectors that have taken most of my data
Meet the Speakers of Soapbox Science Brussels 2025!
Say hi to the brilliant Nora Colson, PhD researcher at Hasselt University — working at the crossroads of #spacescience and #sustainability.
Nora’s research explores an unexpected partnership: diamonds and #cyanobacteria! Her mission? Finding innovative ways to produce #hydrogen fuel for space missions, paving the way for a greener future beyond Earth.
Catch her live on June 28th, 2PM, at Carrefour de l’Europe / Europakruispunt.

The European Space Agency ESA is 50 years old today. Over the years I have served on various of its committees and working groups and it was always a pleasure (well almost always!). Happy birthday ESA.

Today marks the 50th anniversary of the founding of the European Space Agency
I'm privileged & honoured to have spent 15 of the intervening years working in the Science and Human & Robotic Exploration Directorates.
There are many great experiences on many missions working with many amazing people to share
But 12 November 2014, the day that Rosetta deployed Philae to the surface of Comet 67P/C-G, will forever be my most cherished memory
