Side-by-side comparison of Saturn observed at different wavelengths and times show how differently it appears in infrared, on the left, versus visible light, on the right. Left image is labeled Saturn, Webb Infrared Light, November 29, 2024. Right image is labeled Saturn, Hubble Visible Light, August 22, 2024. In infrared, Saturn has horizontal bands, with bands at the north and south poles appearing darker orange and lightening to tan as they approach the equator. The north and south poles glow a greenish-grey. The rings appear in an icy neon white. White dots, representing several of Saturn’s moons, are labeled Janus, Dione, and Enceladus. In visible, Saturn’s horizontal bands appear pale yellow, with some bands towards the north and south pole having a light blue hue. The rings appear bright white, glowing slightly less than Webb’s infrared image. White dots, representing several of Saturn’s moons, are labeled Janus, Mimas, and Epimetheus.

A time sequence of three panels side by side. From left to right, the panels are labeled November 8, 2025; November 9, 2025; and November 10, 2025. This series of images from NASA’s Hubble Space Telescope of the fragmenting comet C/2025 K1 (ATLAS), or K1 for short, was taken over the course of three consecutive days. The sequence shows the progressive disintegration of the comet over this brief period. Each panel features several bright, fuzzy, blue, streaking lights in a diagonal line from the upper left to the lower right of a black background. In the first panel, four comet-like objects appear. The largest is the second from the upper left. In the second panel, the largest object has broken into two pieces. In the third panel, the pieces appear to be moving away from each other along the invisible diagonal line.

Side-by-side images of the same nebula show how differently it appears in near-infrared, on the left, versus mid-infrared light, on the right. Left image is labeled NIRCam and the right is labeled MIRI. In near-infrared, the nebula’s outer bubble has a white edge and its inner clouds are orange, with a distinct dark lane cutting vertically through the center. Stars and background galaxies appear around the nebula and through the outer bubble. In mid-infrared, the outer bubble has a bluish tint and there is more material in the inner clouds, which are colored off-white. The vertical dark lane is still present but more interrupted and covered by the clouds. Material appears to be erupting out the top of the nebula, and this effect is mirrored to a lesser degree at the bottom, opposite end.

This artist’s illustration represents the start of the alert stream from NSF–DOE Vera C. Rubin Observatory. The summit facility is shown on a rocky ridge. The night sky features stars and the glittering band of the Milky Way Galaxy. The sky is populated with multiple alert “pings,” representing individual alerts from Rubin that something in the sky has changed in brightness or position. Different icons represent various types of alerts, including asteroids, supernovae, active galactic nuclei, and variable stars.

In the image center, an opaque oval cloud of gray gas aligned from 1 o’clock to 7 o’clock hides a star. Two strong beams of light from the star emerge from large holes in both sides of the cloud, forming narrow cones extending toward 10 o’clock and 4 o’clock. The central cloud is surrounded by concentric, wispy shells of gas illuminated by the star’s light. The shells reflect extra light where they’re hit by the twin beams. A crowd of smaller stars with cross-shaped spikes over them surrounds the nebula on a black background.

$A wide field of view showing deep space, dotted with many small galaxies and a few foreground stars that display six diffraction spikes. One galaxy is highlighted with a magnified image in a graphic pull-out box in the lower right corner. The galaxy is labeled MoM-z14 and appears as a blurry yellow blob with a small red area at its top.$
