As promised: In this (beautiful) paper (@AandA_journal), led by Elena Lacchin (@5pace0ddity), we used NBSymple (my mighty N-body code) to see what happens to very massive #globularclusters that form a second stellar generation at their centre: https://t.co/EDUwKzpNki

Happy #StellarMonday! Today's topic: the stellar populations within globular clusters (GCs). For years, it was assumed that GCs are pretty simple: single age, single metallicity star clusters, indicative of coeval formation from a single gas cloud of fixed chemical abundance.
In honor of the very first science observation with #JWST being NIRCam and NIRISS imaging of the globular cluster M92, today’s #StellarMonday topic is globular clusters! Globular clusters (GCs) are coeval, ancient, and extremely dense collections of ~1 million stars. [1/10]
Our new paper (with myself, @ajvengelen, V. Gluscevic, and N. Battaglia) shows how we can measure the circumgalactic medium of @VRubinObs galaxies, applying a method developed for reionization (by @CoraDvorkin & K. Smith) to CMB data from @DOE_Stage_4_CMB

💥This X-ray image of supernova remnant G292.0+1.8 shows a rapidly expanding, intricate debris field that contains large amounts of oxygen (yellow & orange) and other elements such as magnesium (green) and silicon & sulfur (blue) that were forged in the star before it exploded.

It's #CatDay and we're feline it! This space #kitty is the result of the #cat-astrophic explosions of two unrelated stars. The fur-tunate alignment of their supernova remnants is claw-fully a-mewsing! This post litter-ally just scratches the surface: https://t.co/kKgX3fk4Xp
With the summer #Olympics coming to a close, our eyes are set on the upcoming winter event. #ClosingCeremony
But on a changing planet affected by the #climatecrisis, the winter sports we know and love are at risk.
Here's why 👇

"I do not think it is possible really to understand the successes of science without understanding how hard it is - how easy it is to be led astray, how difficult it is to know at any time what is the next thing to be done."
- Steven Weinberg (1933-2021)
