This Webb image of Jupiter shows stunning details of the majestic planet in infrared light. In this image, brightness indicates high altitude. The numerous bright white ‘spots’ and ‘streaks’ are likely very high-altitude cloud tops of condensed convective storms. Aurorae, appearing in red in this image, extend to higher altitudes above both the northern and southern poles of the planet. By contrast, dark ribbons north of the equatorial region have little cloud cover.

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 image of SNR 1987A was taken with Webb’s Near-Infrared Camera. At the center, material ejected from the supernova forms a keyhole shape. Just to its left and right are faint crescents newly discovered by Webb. Beyond them an equatorial ring, formed from material ejected tens of thousands of years before the supernova explosion, contains bright hot spots. Exterior to that is diffuse emission and two faint outer rings. Image credit: NASA / ESA / CSA / M. Matsuura, Cardiff University / R.

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