"Astronomen zien oudste supernova ooit"

-> "Astronomen hebben het licht opgevangen van een zware ster die een miljard jaar na het ontstaan van het heelal is geëxplodeerd. Het is de oudste supernova die we tot nog toe hebben gezien – en mogelijk de oudste die we ooit zúllen zien."

-> "Het onderzoek toonde ook aan dat de ster die ontplofte maar weinig elementen naast waterstof en helium bevatte"

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.)

🇬🇧 resident, 🇩🇪 passport, 🇪🇺 in ❤️ & 🧠.

Pretty queer. 🏳️‍🌈🏳️‍⚧️

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

#Portal #Space Systems says its orbit-shifting #Starburst spacecraft will take advantage of technologies that are being developed for its more powerful #Supernova satellite platform. https://www.geekwire.com/2025/portal-space-starburst-maneuverable-spacecraft/

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

💥 What Will the Betelgeuse Supernova Be Like - And Will It Hurt Us? • Universe Today

｢ 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 ｣
