The images, which were posted to the Korean Aerospace Research Institute (KARI) website, show a variety of lunar landscapes, including two jaw-dropping black-and-white images of an enormous Earth rising over the moon's crater-studded horizon, and a time-lapse image of the moon's orbit around Earth taken over several hours.

Zamani (ESA/Webb)) Scientists using the James Webb Space Telescope (JWST) have observed and measured the coldest ice in the deepest reaches of an interstellar molecular cloud to date. The frozen molecules measured minus 440 degrees Fahrenheit (minus 263 degrees Celsius), according to new research published Jan. 23 in the journal Nature Astronomy.
