Amateur astronomy. Retro tech. Mead, perry and beer making. Advocacy: Universal healthcare in Ireland, disability rights in the Constitution, defend the Good Friday Agreement, repeal the 27th Amendment. Reunification of Ireland as a secular republic. That everyone can participate fully here matters, and for that reason when I repost toots that have images it will only be those with Alt text. #Ireland #Disability #Astronomy #Think32 #Cork Daon Phoblacht Corcaí 🇮🇪 #noBridge #noAI

“Even though these supernova events can shine brilliantly, with typical intrinsic brightnesses that are about the equivalent of ten billion suns, that only represents a tiny amount of the energy liberated during a core-collapse event: between 0.1% and 1% of the total energy generated.” 😮 #astronomy #cosmology
