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.)

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.

Image description: The left two-thirds of the frame shows a field of small galaxies on a black background. Near the center of the image, a long, thin line is outlined with a white box and labeled A. At upper right, a red swoosh nearly encircling two galaxies is outlined with a white box and labeled B. The right third of the frame shows zoomed in views of the two regions in the boxes. At top in box A, a thin mottled line extends from upper left to lower right with a handful of background objects. At bottom in box B, a red swoosh wraps around from upper left to lower right, nearly encircling two small galaxies located at one o’clock and seven o’clock.

Two stars both alike in dignity, in the fair Southern Ring planetary nebula where we lay our scene...

Here our “star-crossed lovers” are actually a dying star expelling gas & dust, in orbit with a younger star that is helping to change the shape of this nebula’s intricate rings by creating turbulence. The James Webb Space Telescope can see through the gas and dust in unprecedented detail. In thousands of years, these delicate, gaseous layers will dissipate into surrounding space.

This image is from Webb’s NIRCam instrument, which saw this nebula in the near-infrared.

The Southern Ring nebula is called a planetary nebula. Despite “planet” in the name, which comes from how these objects first appeared to astronomers observing them hundreds of years ago, these are shells of dust and gas shed by dying Sun-like stars. The new details from Webb will transform our understanding of how stars evolve and influence their environments.

Image description

A planetary nebula, seen by the Webb telescope’s NIRCam instrument, against the blackness of space, with points of starlight behind it. The nebula itself is shaped like an irregular oval, with lacy, reddish orange plumes of gas and dust. Further inside the circle, the gas and dust glows bright blue. A glowing white ring separates the red and blue gases. In the center of the rings are two stars, one glowing much brighter than the other, with diffraction spikes radiating out from it.
