NASA's Chandra X-ray Observatory is sending you a holiday card with four new winter-themed images that contain X-rays from Chandra and data from other telescopes, including our friends at @NASAHubble and @NASAWebb. Each object in the collection gives a wink to wintertime cheer, either in its name or shape. 1) The Snowman Galaxies, NGC 4782 & NGC 4783: a pair of colliding galaxies about 210 million light-years from Earth. @NASAChandraXray and @NASAHubble Credit: X-ray: NASA/CXC/SAO; Optical: NASA
