1000 Days in Space for Webb

Today is Webb’s 1000th day in space! ?? Our #UnfoldTheUniverse "Lifer" checklist: -A spacecraft impacting a moving asteroid -Dust in unexpected places, from supernova remnants to early galaxies -Atmospheres of exoplanets: small and rocky to large and gaseous; cold and hot; and sometimes no atmosphere at all -Early black holes -The farthest galaxy (so far!) What's your favorite discovery? Image Description: An artist's depiction of Webb floats above Webb imagery that spells out the number 1000 against a black backdrop of galaxies and stars in blue and orange. The number one is a stretched out, orange, lensed galaxy. The first zero is the Southern Ring Nebula, with a roughly circular cavity filled with aqua-colored gas surrounded by a ring of red gas, with a star at the center. The second zero is a mid-infrared image of merging galaxy pair Arp 107, like a ghostly blue wagon-wheel with a bright center. The final zero is Jupiter, striped in grayish blue and beige with green and orange glows at the poles due to auroras.
