A two-panel image split down the middle vertically. At the left is the Vega disk as imaged by the Hubble Space Telescope. The disk is perfectly circular, and at the center is a black spot blocking out the bright glow of a star. Closer to the center, the disk is white. Radial striations extend out from the center, giving a ripple effect to the disk like the end of a sausage casing. The outer edge of the circular disk is blue. At the right, the Webb image of the disk is an orange colored, smooth, fuzzy halo. The inner disk is whiter toward the center, and there is darker lane between the inner disk and the more orange outer disk. The disk is also perfectly circular, with a black circle in the center blocking light from the star.

The top-left half of the image is a Hubble Space Telescope view of a 100-billion-mile-wide disk of dust around the summer star Vega. The disk is represented in blue. The color trails to white as we get closer to the center of the disk. The black spot at the center blocks out the bright glow of the hot young star. The disk is perfectly circular because we are looking down on top of it. The lower-right half of the image is a view from the James Webb Space Telescope, which reveals the glow of warm dust in the disk's halo that is colored orange. The disk is brighter toward the center. There is a notable dip in surface brightness between the inner and outer disk.

Two visualizations using Hubble and Webb data. The left image is from visible-light data collected by Hubble. The right visualization is from infrared-light data collected by Webb.

This image is a mosaic of visible-light and infrared-light views of the same frame from the Pillars of Creation visualization....

Mosaic of the Pillars of Creation visualization model, composed of 4 rectangular strips oriented 45 degrees clockwise from vertical. Strips alternate between Hubble and Webb views of the visualization model, with each strip labeled: “Hubble” at lower right corners of first and third strips; “Webb” at upper left corners of the second and fourth strips. Webb strips have drop shadows that make it look like they are overlaid on top of larger Hubble image. Mosaic shows 3 vertical structures (pillars) of thick smoke-like material. Pillar edges are glowing, with thin wisps of material moving away into space. In Hubble strips, pillars are dark brown and opaque, on greenish blue background. In Webb strips, pillars are bright orange to brown with a distinct area of bright red at the top of middle pillar. A red star appears at the tip of a peak in the left pillar and the background is deep blue.

A horizontal, two-panel image of pixelated, black-and-white star fields. The left image label is: “Webb Near-IR.” It holds a few dozen points of light of varying brightness. At the center of the image, a circle marks one bright point. The right image label is: “Hubble Near-IR.” It holds more indistinct, blurry patches whose overall brightness is similar to the more defined regions in the left image. At center, a circle marks a light gray pixel.

A spiral galaxy with a small bar of bright-white stars at its core. Two main spiral arms extend outward from each end of the bar. They appear to fork into multiple branches beyond the galaxy's core. The spiral arms have a lavender hue. Bright-white and bright-red stars dot the galaxy. Reddish-brown dust lanes line the inner curves of the spiral arms.

A field of galaxies on the black background of space. In the middle, stretching from left to right, is a collection of dozens of yellowish spiral and elliptical galaxies that form a foreground galaxy cluster. Among them are distorted linear features, which mostly appear to follow invisible concentric circles curving around the center of the image.
