Happy birthday to British-born, American #astrophysicist Margaret Burbidge (1919-2020) who was one of the people instrumental in building our understanding of stellar nucleosynthesis, how nuclei are produced in stars & you and I are all stardust! She was the 1st author of a monumental scientific paper Synthesis of the Elements in Stars, which became known as B2FH from the initials of its authors: Margaret Burbidge, Geoffrey Burbidge (her

Happy birthday to #astrophysicist Jocelyn Bell Burnell! In 1967, as a grad student she discovered the 1st radio pulsar, a highly magnetized, rotating neutron star that emits a beam of EM radiation. This radiation can only be observed when the star is pointed towards us; so, like the light from a lighthouse, it appears to pulse at a precise frequency. She had been working with her supervisor Antony Hewish & others to construct a radio telescope to study quasars. #linocut #printmaking #histsci

Happy birthday to #astrophysicist Cecilia Payne-Gaposchkin (1900-1979), a trailblazer for women in #astronomy who discovered that hydrogen & helium are the most common elements in the universe.⁠

Born England, she won a scholarship to Newnham College at Cambridge in 1919 where she heard a lecture which changed her life. She wrote, “My world had been so shaken that I experienced something very like a nervous breakdown.”

went to a talk last night by a prominent #astrophysicist (which is why I was remiss in posting) & I can't stop thinking about Kessler Syndrome.

The #printerSolstice2425 prompt this week is iron, so after talking last week about how certain numbers of nucleons are "magic" as you grow increasingly large nuclei, now we're talking about how you do that: how you grow nuclei from a single proton to the largest naturally-occurring transuranic elements. British-born, American #astrophysicist Margaret Burbidge (1919-2020) is 1 of the people instrumental in building our understanding

Making my #linocut portraits of #astrophysicist Margaret Burbidge (1919-2020) for #PrinterSolstice2425 prompt: iron! It’s about how most of you and I are stardust, made of elements built in stars through stellar nucleosynthesis. Supergiant stars build elements up to iron through nuclear fusion. In a famous paper known as B2FH, first-authored by Margaret Burbidge, they reviewed everything known about stellar 1/2

Working on my next #linocut for #printersolstice2425 - last week we talked about how some numbers of nucleons (neutrons and protons) are “magic” so sometimes if you add another the binding energy is lower than the last, so the resulting nuclei are more common and stable. This week is about how you do that…. How you add nucleons to nuclei and grow heavier elements.
