AGU is deeply disappointed in SCOTUS decision to overrule the order blocking the dismantling of fed agencies until we could make our case about the President’s unlawful actions.  The harm this will cause is shocking. However, we will continue to fight for the rule of law.

NASA Goddard is pushing through a 48% staff reduction!!! This could impact the upcoming Roman Space Telescope and many other future Astro missions. News coverage seems not sensational enough. Are we really going to let NASA (as we know it) die quietly? www.space.com/space-explor...

Check out this recent article I was a co-author on: "Citizen Science in Space and Atmospheric Sciences: Opportunities and Challenges" link.springer.com/article/10.1... Here's a thread of the main points outlined in our paper! #heliophysics

Today I gave a seminar on the topic of my doctoral dissertation, and with that, I have now completed all of my doctoral studies. ... Aside from the thesis. Still gotta finish writing that. And then defend it.

Breaking space news: We have made our own solar eclipse in space! 🌘 Today, we release the first images from our Proba-3 mission, which flies two spacecraft in precise formation to create artificial solar eclipses in orbit. Learn more ➡️ www.esa.int/Enabling_Sup...

Inspired by @jtuttlekeane.bsky.social and @ohdearz.bsky.social, here's what the White House proposed budget cuts to NASA would do to the entirety of the agency's Science Mission Directorate. Bloodbath is right.

I'm excited to share that I was awarded the the Marie Skłodowska-Curie Postdoctoral Fellowship! Starting this October, I will work on plasma shocks in the heliosphere at QMUL. Looking forward to new endeavors!

THIS FRIDAY: Can we halt the illegal mass firings of our federal scientific workforce? We will argue in District Court this week for a temporary restraining order on the execution of Trump’s Executive Order.

I want to draw your attention to our Community-Driven session titled 'Refining the Sunspot Number Series: Challenges and Benefits for the Space Climate Community' at this year's hybrid European Space Weather Week meeting.☀️ The abstract deadline is 15th of May. events.spacepole.be/event/222/ab...

At #EGU2025 I talked today about our catalogs for #solastorm observations and how they are used for enhancing #spaceweather forecasting. Plus gave a quick outlook of how data of the new PUNCH @punch-mission.bsky.social mission can be used in connection with many other spacecraft in the heliosphere!

Our collisionless shocks session at #EGU25 drew a great crowd, sparked insightful discussions and set the stage for new #heliophysics collaborations. Thanks to everyone that attended!

My #EGU25 unfortunately started with a headache that made me miss the first day :( But I will try my best to give a good talk about rotational discontinuities and magnetosheath jets tomorrow at 9:10 in room 0.94/95.

Our team at the Austrian Space Weather Office has 5 presentations as lead-author at this weeks #EGU25 in Vienna, and we (co-)convene 3 sessions! We show our work on forecasting #solarstorms and observations with multiple spacecraft, using #AI methods for their detection and #solarwind modeling! ☀️💥

One of the employees fired from NASA told me how much their career meant to them: "Prior to everything happening today, NASA has been an incredible place to work — to dream big, to innovate, to do things that I never thought I could have done.” Words by me. 🧪 www.nature.com/articles/d41...

Dear US colleagues, In response to the Trump administration, my university @univ-amu.fr is setting up a new program dedicated to welcoming American scientists wishing to pursue their work in France. There are several M$ in the budget. www.univ-amu.fr/en/public/ac...

A friend included this anti-acknowledgement section on her PhD thesis. She also added the proposition: “Systematic bullying and undermining of girls and women in STEM starts early on and is the reason why they do not stay in science and related fields.” Absurd we still need to go through this 🧪👩‍🔬

🌎 From tracking extreme weather to protecting fisheries and coastlines, #NOAA’s work saves lives and supports economies. AGU opposes the dismantling of NOAA and calls on Congress to defend this critical agency. The future of climate science, public safety, and industry depends on it.

We wanted to know what makes the Martian bow shock asymmetric. We found that at any one instant it can be quite asymmetric, but on average these asymmetries cancel out to a large extent. The bow shock is actually quite dynamic. Read the new paper by Sara Nesbit-Östman et al. doi.org/10.1051/0004...

Hooray, SDO images are back!

With data from NASA's Solar Dynamics Observatory available again, my timeline is once more full of beautiful images/movies of the Sun. If anyone has ever wondered how to make solar movies like these, I've just uploaded a detailed tutorial to YouTube! (Link below)
