Everyone is obsessed with the JWST but no one’s paying attention to my dude Hubble still killing it.
Our universe is so capricious it sometimes likes to play a game of hide and seek. In 2017, astronomers were surprised to see a huge shadow sweeping across a disk of dust and gas encircling the nearby young star TW Hydrae. The shadow is cast by an inner disk of dust and gas that is slightly tilted to the plane of the outer disk. The shadow can only be clearly seen because the system is tilted face-on to Earth, giving astronomers a bird’s-eye view of the disk as the shadow sweeps around the disk like a hand moving around a clock.
