Congratulations!

Suomen Akatemia valitsi 11 uutta tutkimuksen huippuyksikköä Suomen Akatemia on valinnut uudet tutkimuksen huippuyksiköt ohjelmakaudelle 2026–2033. Huippuyksikköohjelmaan valittiin 11 yksikköä, joissa työskentelee tutkimusryhmi&au...

Olen niin iloinen ja ylpeä saadessani ilmoittaa kahdesta uutisesta: 1) Avaruusresilienssin huippuyksikkömme valittiin Suomen Akatemian huippuyksikköohjelmaan (2026-2033) ja 2) minut valittiin Akatemiaprofessoriksi (2026-2031)! Mahtavat fiilikset! www.aka.fi/tietoa-suome...

Look at how round this bird is!!! Bird of the year!!

Bird of the Year voting opens tomorrow, and it is an outrage the takahē is yet to win. I'd like to take this opportunity to urge you to vote for the hide-and-seek legend from Fiordland, the roundest birb, and the one true pick for all you railfans out there

4-panel Comic. (1) STUDENT: If the wavefunction only collapses when I observe it, does that mean my consciousness affects the universe? (2) [Bad:] PROFESSOR: Yes, quantum entanglement proves that we all have souls. (3) [Good:] PROFESSOR: No, consciousness plays no role here. It’s just physical measurement. (4) [Chaotic:] PROFESSOR: No. The wavefunction collapses when *I* look at it because I’m a full professor. It won’t collapse for an undergraduate.

My PhD thesis has now been submitted for pre-examination 🎉

Which means that it's time for me to take some time off 🌴

Just heard from @tmelnik.bsky.social that DSCOVR is offline. Recovery attempts have not been successful. It's going to be a significant, if not permanent, outage.

Halibut Crochet Pattern (U.S. National Park Service)

TIL (on mastodon) that the US National Park Service has crochet patterns!

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 begins push to slash workforce with more staff buyouts, early retirements as budget cuts loom NASA employees have until July 25 to decide if they'll stay or go.

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"

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.

Magnetosheath Jets Associated With a Solar Wind Rotational Discontinuity in a Hybrid‐Vlasov Simulation We conduct a 2D hybrid-Vlasov simulation of the interaction between Earth's bow shock and a solar wind rotational discontinuity Magnetosheath jets that form during the shock-discontinuity interac...

My latest paper, regarding magnetosheath jet formation associated with a solar wind rotational discontinuity, is now published!

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.

It feels like they're trying to turn universities into degree factories.

It's unfortunately the same here in Finland. The government is cutting research funding, while at the same time trying to increase the number of university students, and the employer union is trying to remove caps on teaching hours for university staff.

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 University of Helsinki has put this introductory course on "Sustainable Space" online, covering topics such as #spacedebris, #spaceweather, #solarwind, magnetosphere, and ionosphere, atmosphere, as well as basics of satellites, orbits, and launchers.

Yes please, the resolution of the image is not quite high enough to actually read it 😅

Ah, great, now I can finally see your poster!

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!

Happy to report that my talk went well! #EGU25

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.
