The galaxy AM 1054-325 has been distorted into an S-shape from a normal pancake-like spiral shape by the gravitational pull of a neighboring galaxy, seen in this Hubble image; a consequence of this is that clusters of newborn stars form along a stretched-out tidal tail for thousands of light-years, resembling a string of pearls.

Left: this image from the Multi Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope shows the parent cloud LHA 120-N 180B in which the HH 1177 system was first observed. Center: this image shows the jets that accompany HH 1177; the top part of the jet is aimed slightly towards us and thus blueshifted; the bottom one is receding from us and thus redshifted. Right: this image from ALMA shows the rotating disk around the star, similarly with sides moving towards and away from us. Image credit: ESO / ALMA / NAOJ / NRAO / McLeod et al.

This image from Webb’s NIRCam short-wavelength channel shows the Orion Nebula, its stars, and many other objects in unprecedented high definition in the near infrared. Many of the young stars are surrounded by dense disks of gas and dust which may be forming planets. In other cases, those disks are being destroyed by the intense ultraviolet radiation and strong winds from the most massive stars in the region. Many of these photoevaporating disks are visible if you zoom into the image. Image credit: NASA / ESA / CSA / M. McCaughrean / S. Pearson.

$This Webb image shows a pair of actively forming stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center. The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars. Image credit: NASA / ESA / CSA / Joseph DePasquale, STScI.$
