Did Venus Ever Have Oceans? (Exploring Space Lecture Series)
YouTube video by Smithsonian National Air and Space Museum
www.youtube.com
I had the great privilege this week of giving a lecture at the Smithsonian National Air and Space Museum about the possibility that there were once oceans on the surface of Venus, and why missions like DAVINCI and VERITAS are critical to answering big picture questions about planetary habitability🧪🔭

🔬 Nouveau regard sur l’atmosphère terrestre !
Des chercheurs de l’IPGP analysent des gaz rares piégés dans des quartz vieux de 3 milliards d’années.
Ils révèlent :
• un fort dégazage mantellique
• une atmosphère archéenne plus riche en xénon → échappement vers l’espace

My new paper is out in GCA: What do incipient metal–silicate differentiation processes look like in early Solar System feedstocks? Do HSE patterns link winonaites genetically to main-group IAB irons or only certain IAB subgroups? Give it a read here: authors.elsevier.com/sd/article/S...

I voted for #Cuprosklodowskite not least because it’s a spiky, poisonous, radioactive rogue who’s mad, bad & dangerous to know. But I think the main reason I love it is that, like so many Mineral Cup entries, I had never heard of it before & now have an intense emotional attachment to it. #MinCup25

You have discovered a planet. It is obscured by a dust cloud. It has clouds made of xenon. Maybe you could visit there.

🚨New Paper Alert!🚨
I've got a new paper out in Science Advances where we show that the 2 byr old Chang'e 5 magma came from shallow depths in the lunar mantle, and that melting was likely driven by top-down heating of the mantle by radioactive decay in a sub-crustal KREEP layer.

The chemistry of the youngest lunar lavas and experiments show how the mantle stayed hot enough to melt for billions of years.

I think that studying something is a way of loving it, and the care and detailed attention of a work like this really embodies that here:
When the Lunar Orbiter 4 spacecraft gave us our first good view of the Orientale basin it was revelatory. Not only was this giant multi ringed impact basin first revealed in its general form, other such basins were recognized across the Lunar near side. Oil paints on canvas panel.
