NASAさんのインスタグラム写真 - (NASAInstagram)「🎇 They’re not quite fireworks, but stars and galaxies in @NASAWebb’s image of an early strand of the “cosmic web” sparkle in the sky. Ten galaxies in this image existed just 830 million years after the big bang. Talk about historic! Happy #FourthOfJuly! Image Description: A black field speckled with a variety of galaxies of numerous shapes and sizes. The galaxies are white, yellow, blue and red. Red is the predominant galaxy color in the field, indicating very distant galaxies. Eight small white circles mark the position of 10 galaxies (two circles contain more than one galaxy). The 10 galaxies are arranged in a diagonal, thread-like line from the bottom left to the top right. Most of the white circles are separated. However, there is a pair of circles grouped together on the bottom left, as well as a cluster of three circles on the right side of the image. A quasar called J0305-3150 appears in the middle of that right cluster. Within the quasar’s circle, there are strong red diffraction spikes radiating out from a white core. Galaxies in the other circles are seen only as red specks. #Space #NASA #JWST #Webb #UnfoldTheUniverse #July4 #Fireworks」7月4日 23時20分
