Time for an updated #introduction:
I’m Jost (they/them). PhD in astroparticle physics ( #supernova #neutrinos), now Senior Research Software Engineer at King’s College London. I help researchers across the university write better code to enable better research. (Still work on software for @HyperKamiokande & @SNEWS part-time.)

Pretty queer. 🏳️🌈🏳️⚧️
I sometimes do LGBTQ+STEM or astroparticle physics outreach; slowly learn Japanese; listen to too many podcasts.

A Seattle-area startup called #Portal #Space Systems has successfully tested the solar thermal propulsion system for its #Supernova transorbital spacecraft, marking a first for the space industry. https://www.geekwire.com/2025/portal-space-solar-thermal-propulsion-system-test/
💥 A supernova may soon be visible in the sky
｢ For more than a century, astronomers have been closely observing V Sagittae, a double system located more than 10,000 light-years from Earth, with highly unstable behaviour and luminosity. And in this system are a massive star and a white dwarf, linked by an orbit only twelve hours apart ｣

There's been a supernova and WAS astrophotographer Carl Lancaster has the before and after of this star blowing it's guts out into the universe, erupting in "nearby" galaxy NGC 7331, 40 million light-years away in the constellation Pegasus. Officially known as SN 2025rbs, it is a type 1A supernova, a type of supernova that occurs in binary systems in which one of the stars is a white dwarf. #SN2025rbs#Supernova#WestportAstronomicalSociety

｢ It will be visible during the day. It will be brighter than any planet. It will be almost as bright as the full moon. You'll be able to read a book by the light of the Betelgeuse supernova at midnight ｣
