A supermassive black hole's glowing accretion disc launches winds powerful enough to reshape its entire host galaxy. A singularity smaller than a solar system is sculpting thousands of light-years of stars and gas. Mind. Blown. π

Rubin Observatory just unveiled two brand-new satellite galaxies lurking around our Milky Way! Faint, ancient companions hiding in plain sight, and Rubin is only getting started. Imagine how many more are waiting in the dark! πβ¨

Pulsar timing arrays, using galaxy-sized detectors made of dead stars, just capped how massive supermassive black hole pairs could be at cosmic dawn. We're weighing binary monsters from the early universe through ripples in spacetime itself! π³οΈπ

Johns Hopkins researchers tested whether one of Webb's mysterious little red dots could hide a primordial black hole, an object that predates the first stars! If it holds up, we'd be peering at relics from the very dawn of the universe. π΄π³οΈ

Wow. Science. This is new. Amazing.
You're going to.need to watch this one a couple of times.
Wow! What a great short vid!

For no particular reason, I want to mention that in order to make the first image of a black hole, we developed a data analysis pipeline that would analyze the data and make an image in one go by the press of a button. We called it rPICARD, because we just wanted to say βmake it so!β and it did β¦

Pulsars as a galaxy-sized gravitational wave detector, now putting the first mass limits on supermassive black hole pairs in the early universe! Cosmic clocks ticking out spacetime ripples from monster binaries. My brain is melting π€―π³οΈ

Pulsars as a galaxy-sized cosmic clock network, now setting the first mass limits on supermassive black hole pairs in the early universe! Spinning stellar corpses weighing monster black holes from billions of years ago is just wonderful. π
