She’s worked with computer simulations like this for years - but now, she can work with real images. Much of Goodman’s work compares numerical simulations of physics in the universe against scientific observations. It's really hard to appreciate it all at once.” “It's like this mishmash of galaxies of all different ages. “When you look out deep, deep into the universe, you are looking back in time because it took the light such a long time to get here,” Goodman says. The tiny smudges in the images represent the farthest away galaxies - which formed close to the beginning of the universe, Goodman says. The images show stars and galaxies at a wide array of distances, from within the Milky Way to galaxies far, far away. Harvard University astronomy professor Alyssa Goodman and her colleagues have been waiting a long time for this moment. The images show galaxies more than 4.6 billion years old. The high-resolution color photos released Tuesday from NASA's largest and most sophisticated telescope ever built show the universe in a way astronomers haven’t seen it before. New images from the James Webb Space Telescope show the reaches of the universe in the most stunning detail ever captured. Facebook Email A detailed image of galaxy cluster SMACS 0723. ![]()
