Vibert Douglas fought against gender discrimination in her field, earned an MBE for her war service, was a celebrated astrophysicist and one of the first individuals to receive the Order of Canada.
This is her remarkable story.

On this day in 1983, Gabrielle Roy died in Quebec City. Born in Saint Boniface, Manitoba, she became one of Canada's most celebrated authors. Her 1945 book Bonheur d'occasion (The Tin Flute) was a landmark work in Canadian literature. She has seven schools named for her.

I recently visited the ALMA observatory in Chile. While I was poking around the telescopes, ALMA researchers released amazing new views of planet-forming disks around young stars.
These are the most detailed images yet of new solar systems being born. 🧪🔭

Awesome news. Rubin is the scientist perhaps most closely identified with the discovery that galaxy rotation cannot be explained with Newton’s law of gravity applied to the gas and stars they contain. This led directly to the idea that dark matter dominates the gravity of galaxies at large radii. 🧪
Vera Rubin has been selected to be featured on the back of a quarter. She is the first astronomer to be honored this way. Read about her research on the Andromeda galaxy and how it led to the discovery of dark matter in this article written by Rubin herself. doi.org/10.1063/1.24...

Ok that’s cool - even the Oort Cloud has a spiral….
Far beyond Pluto, trillions of cold comets circle the sun in a lazy swarm called the Oort Cloud. A new simulation indicates what this comet-cloud looks like: a loose spiral that resembles a miniature galaxy. 🧪🔭
