These images were released to commemorate the 25th anniversary of Chandra. They represent the wide range of objects that the telescope has observed over its quarter century of observations. X-rays are an especially penetrating type of light that reveals extremely hot objects and very energetic physical processes. The images range from supernova remnants, like Cassiopeia A, to star-formation regions like the Orion Nebula, to the region at the center of the Milky Way. This montage also contains objects beyond our own Galaxy including other galaxies and galaxy clusters.

The Crab Nebula is the result of a bright supernova explosion witnessed by Chinese and other astronomers in 1054 A.D. Chandra sees the rings around the pulsar and the jets blasting into space. X-rays from Chandra (blue-violet and white) and IXPE (purple); optical from Hubble (red, green, and blue)

Visual Description:
This composite image features the remnant of a supernova explosion, which resembles a neon purple mushroom at the heart of a colorful web of veins and filaments. Known as the Crab Nebula, the heavily veined blue and red cloud of gas is set against the blackness of space. At the core of the nebula is a pulsar, a rotating neutron star emitting electromagnetic radiation. Here, the pulsar appears as a bright white dot sitting in a neon purple cloud. Surrounding the dot are white rings. These are created by particles driven away from the pulsar and colliding with gas in the nebula to produce X-rays. From this angle, the rings and purple cloud combine to resemble a mushroom cap. Completing the look of a mushroom is a thin mushroom stem emerging from the white dot. This is a narrow beam of particles blasting away from the pulsar.

The cloud creates a border around the entire plate, like a thick swirling smoke ring. Beyond it, in the open center, is a vast field of specks. These specks are young stars observed by Chandra. Within the central field, two cluster groupings are suggested by separate swirls of faint mist. One sits near our upper right. The other is near the bottom left, partially obscured by the ring cloud.

This tactile plate is a physical relief map based on the intensity of X-ray, infrared and optical data. This composite plate features a close-up of the supermassive black hole at the heart of the spiral galaxy known as NGC 1365. The black hole pushes out of the plate at the center, its outer edges raised and mottled. From this core, two thick ropey arms spiral out. Continuing their spiral curves, the arms extend well beyond the edges of the frame. Dotting the plate are a series of pointed, cone-like spots. These are stars paired with smaller black holes or neutron stars, observed by Chandra.

This tactile plate is a physical relief map based on the intensity of X-ray, infrared and optical data. In this composite plate, a pulsar, a pulsar wind nebula, and a low energy X-ray cloud combine to create an uncanny shape of a skeletal hand preparing to grab a glowing ember. The hand reaches up from the bottom of the plate, the ghostly bones representing pulsar wind nebula X-rays observed by Chandra. A raised spot in the wrist is the pulsar itself. Just beyond the hand’s fingertips, near our upper right, is a mottled shape, the low energy X-ray cloud observed by Chandra.

This tactile plate is a physical relief map based on the intensity of X-ray, infrared and optical data. This composite plate features an ultra-luminous infrared galaxy, surrounded by a soft, puffy cloud of X-ray gas. Named Arp 220, this galaxy is the result of a collision between two galaxies, each about the size of our own Milky Way. Here, a single, raised dot sits at the center of the plate. The mottled cloud surrounding the dot appears soft and airy, like cotton candy. Upon close inspection, faint veins can be discerned, marbling the X-ray gas cloud detected by Chandra. Surrounding the gas cloud are other distant galaxies and stars, set against the vastness of space. They range from tiny specks to small, ridged ovals.

This tactile plate is a physical relief map based on the intensity of X-ray and infrared data, showing Jupiter. The fifth planet from the sun is set against the vastness of space, flanked by puffy blobs. Jupiter is presented in exceptionally clear focus. More than a dozen bands of swirling gas streak the surface, each a different texture. The gas giant is encircled by a fine ring, and a large storm swirls on its surface at our lower right. At the top edge of Jupiter, tilted just to our right of center, is a slightly fuzzy, raised strip. A similar, smaller line can be found at the bottom edge of the planet. Capping the planet’s magnetic poles, these strips represent X-ray auroras, created when high-energy particles collide with gas in the planet’s atmosphere. At our right and left, large blobs flank Jupiter, some larger than the gas giant itself. Like the auroras, these clouds represent X-rays observed by Chandra.

This tactile plate is a physical relief map based on the intensity of X-ray, infrared and optical data. This composite plate features a double star cluster, a cloud, and several dots. This double cluster is part of the Large Magellanic Cloud, a companion galaxy to the Milky Way. The myriad stars in the larger cluster fill the upper center of the plate. The other cluster is much smaller and coincides with one of several circles located slightly above and to the right of the plate’s center. This and the other circles are X-ray sources detected with Chandra. To our left of the combined cluster is a vertical streak of cloud. Extending beyond the upper and lower edges of the plate, this section of cloud resembles wafting smoke from a cigarette.

This tactile plate is a physical relief map based on the intensity of X-ray and optical data. This composite plate features dozens of tiny specks, each a distinct galaxy. The cluster, known as MACS J0035, is surrounded by a hazy, softly bulging cloud of hot gas detected by Chandra. From this distance, most of the galaxies in the cluster resemble protruding specks and very short streaks. However, upon close inspection, some of the oblong specks and streaks are revealed to have spiral arms.

This tactile plate is a physical relief map based on the intensity of X-ray, infrared and optical data. At the center of this composite plate is a small object resembling a Cheerio. This is supernova SN 1987A, named after the year the core-collapse explosion was first observed on Earth. It is located in the Large Magellanic Cloud, a small nearby galaxy. The Cheerio, or equatorial ring, represents material ejected tens of thousands of years before the supernova explosion. The blast wave from the supernova is striking the ring, causing it to produce X-rays detected by Chandra. Inside this ring is a slightly raised dot containing debris from the star that exploded. The ring sits at the center of a ghostly figure 8, outlined in ridges. This entire structure is surrounded by a packed field of stars, specks and dots. A long, mottled cloud hovers near the left edge of the plate.
