Re-introducing:

Hi all, I'm Anna - an #Earth ⚒️ and #Planetary 🪐 scientist working on the interior dynamics rocky planets🌋, and active in #scicomm 🧪

Currently at NASA JPL/Caltech; soon back in Europe for a new position (stay tuned..)

Part of NASA/ESA #VERITAS & #EnVision space missions 🚀 🔭

NEW: It was a delight to contribute to @quantamagazine.bsky.social's stunning new series on climate science! Naturally, my story tended apocalyptic: will Earth ever become a climate hellhole like Venus, the most extreme world in the solar system?

Why Is Venus Hell and Earth an Eden? | Quanta Magazine

A team of scientists has investigated how Earth’s twin became so inhospitable, and whether the same will happen to our planet.

Venus is a Solar System enigma.

Although Venus is similar in size and distance from the Sun to Earth, it has evolved very differently from our planet.

Our #Envision mission will aim to solve some of the puzzle by thoroughly studying our closest neighbour.

If you are interested in supporting NASA science and exploration, and saving it from capricious budget cuts, here's one thing you can do: sign this petition being sent to Senate and House members of their respective appropriations committees. Two days left to sign!

We're going to learn some tough stuff today about the White House's proposed budget for fiscal year 2026—including what they have in mind for NASA.

I'll share what I hear, but remember:

CONGRESS decides how much money NASA gets, not the White House.

So whatever happens today, the fight continues.

How bad will it be? Catastrophic.

Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.

But, this is the WH's *proposed* budget.

Speak up now before it is too late.

(inflation adjusted $-s below)

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

Yes, the image automatically linked to the JGR:Planet's website is that of the journal's cover - not the paper, cannot adapt it!

Dr. Anna Gülcher @planetaryanna.bsky.social · May 8

Previously published #Venus coronae databases, however, remain inaccessible to the public and/or incomplete -- our new database uses clear ID criteria to define 740 (!!) corona features on Venus, which is much higher than ever reported!

"#Coronae" are defined by a (partial) quasi-circular ring of closely spaced concentric fractures. They are hugely abundant on #Venus' surface and considered key for Venus' tectonic and volcanic history ⚒️🌋
