Greetings to Blue Sky! I’m Sascha and I’m just wrapping up my Honours in Physics at UQ. I’ve been exploring proton-based FLASH therapy for cancer treatment in my project this year and I can’t wait to see where the field takes me next!

Exciting news! My second first-author paper is out on the arXiv today!! arxiv.org/abs/2507.14610
We present a brand new JWST image of the Apep colliding wind binary in the mid-infrared, and we study what this nebula can tell us about the THREE stars in it's centre. Read on for more... 1/?🔭🧪

Four more colliding wind nebulae have been observed with JWST, and just yesterday put on the arxiv! arxiv.org/abs/2505.11616
Yes, those rungs of dust are real and not an imaging artefact!

Is Elmo a Time Traveler? We Talked to Physicists to Find Out
Scientists offer new theories to unravel how it’s possible that, after 44 years, Elmo is still 3.5 years old.

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

The images show oscillations in nine different stars (with false colour to make them pop 🙂 ).

anyone else watching queen putricia? blessed be the bloom!
If you are feeling overwhelmed, I strongly recommend the livestream of the corpse flower at Sydney Botanic Gardens on YouTube. There are currently 1,500 people in chat waiting for a flower to open, and occasionally claiming that it definitely has moved this time.

An underrated feeling is when you meet someone, and you realize you have a mutual friend, so you take a picture together and send it to that friend with no context. What a rush!

Do you like binary stars? How about Wolf-Rayet stars? May I introduce you to my new chapter on what happens when you put WR stars in binaries... awesome colliding wind binaries!
This should be a handy resource whether you're new to or knee-deep in the field! 🔭(1/?)

Many problems in mathematics and physics can be simplified by assuming that any solid body is approximately a sphere, but this approach is likely to lead to a rounding error.
