Crab Nebula: 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.

Orion Nebula: In this composite image, a collection of neon pink and white stars gleam through a haze of wispy clouds. The young stars range in size from tiny specks to plump circles. Many have white cores and are surrounded by neon pink rings, identifying stars detected by Chandra. Some display long, ruler-straight diffraction spikes. Near the upper right of the image is a burst of red cloud that resembles a thick shock of hair. Both the red burst and the collection of stars are muted by hazy clouds, as if viewed through wafting smoke rising out of a campfire.

The Eyes Galaxies (NGC 4438 & 4435): This composite image features a pair of merging galaxies, each resembling a brilliant white dot, earning the pair the nickname ‘The Eyes’. Near our lower left is the galaxy NGC 4438. This bright white dot is surrounded by a neon purple cloud of hot gas seen with Chandra. An inky black cloud nestled in a vertical strip of haze partially blocks our view of the neon purple, superheated gas. At our upper right is the second galaxy, NGC 4435. This bright white dot is surrounded by a thin, neon purple ring. The galaxy sits in the center of a glowing white streak, at the heart of a misty white pool. Flecks of white and neon purple speckle the image, set against the blackness of space.

The Cat's Paw Nebula (NGC 6334): In this composite image of the Cat’s Paw nebula, brilliant red and purple clouds blanket a black sky packed with stars. Throughout this star-forming region of the Milky Way, distinct pockets of glowing, brick red clouds are linked by wisps of purple. A cluster of the brightest stars in the image are found in the heart of the nebula. Many are neon purple, with glowing white dots at their core, representing young stars observed by Chandra.

The Milky Way's Galactic Center: This composite image depicting the center of our Milky Way galaxy features a row of bright spots and translucent swirls, set against a backdrop of purple and red clouds and stars. The clouds show hot gas seen with Chandra. The translucent threads, which are mysterious sources of radio waves, create clusters, streaks, and ribbons. Several of these distinct shapes resemble smoke trails captured on film. While most of the distinct swirls and bright spots sit in an orderly row across the middle of the image, one very bright spot sits at our lower righthand corner. This is the area around Sagittarius C, a bright star forming region, which here resembles a golden white orb ringed with hints of green.
