In this illustration, an exploding star powers jets of material. The star is shown as an almost flower-like shape. The purple �petals� represent clouds of material created in the explosion. The bluish-white and yellow center shows where the newly formed black hole begins driving the jets. The core of the jet pointed toward us is whitish and the broader regions are magenta. In the distance, on the far side of the star, you can see the opposite side of the jet disappearing into space.

In the center is a large, oval-shaped galaxy, with a shining, ringed core. Left of its center is a second, smaller galaxy with two spiral arms. The galaxy pair is so close that they appear to be merging: a tail of material with a few glowing spots connects from one of the smaller galaxy’s spiral arms to the larger galaxy. A faint halo surrounds both galaxies. Several stars are visible around the pair.

Labeled “Artist’s Concept” at bottom right, the graphic shows a closeup of a dwarf galaxy, which appears roughly circular with a light-yellow bar in the center. Faint, blue, wispy, cloud-like features surround this yellow bar, and they are sprinkled with tiny white specks. A wide, wispy, purple arc appears to the left of the galaxy. Trailing the galaxy is a large, faint, wide, tail-like feature.

A spiral galaxy with an oval-shaped disk. Two large arms curve out away from the ends of the disk. Bright pink patches and dark reddish threads of dust fill the arms. The bright pink patches indicate where stars are forming. The core is very bright and filled with stars. Some large stars appear in front of the galaxy. Directly under the point where the right arm joins the disk, a fading supernova is visible as a green dot.

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.
