Youths! Webb observed the galaxy cluster El Gordo, a “cosmic teenager” that existed 6.2 billion years after the big bang. The most massive cluster of its era, it’s a perfect magnifying glass. (Its gravitational pull is so strong that it has bent and magnified light from distant objects behind it.) In the second image, take a closer look at two of the background galaxies magnified by El Gordo. The long thin line in Box A is known as La Flaca, or The Thin One. Webb used its extreme infrared sensitivity to spot a red giant star within, the first star of this type observed beyond 1 billion light-years from Earth. The bright arc in Box B is El Anzuelo, or The Fishhook. Light from this galaxy took 10.6 billion years to reach Earth! Webb peered through its thick curtain of dust to observe star formation and the assembly of galaxies up close. Read more at the link in our bio. Image descriptions: 1. A black background is scattered with hundreds of small galaxies of different shapes, ranging in color from white to yellow to red. Some galaxies appear warped. A handful of foreground stars display eight diffraction spikes. 2. Image with 3 panels. The top panel is the previous galaxy field, cropped to spotlight 2 objects that each have white boxes around them. In the lower left of this top panel is Box A, and at upper right is Box B. The bottom left panel is a close-up of Box A. It shows a thin, mottled line extending from upper left to lower right with a handful of background objects. The bottom right panel is a close-up of Box B. It highlights a red swoosh wrapping from upper left to lower right, nearly encircling two small galaxies. Credits: NASA, ESA, CSA, Jose M.
