Visual Description: Chandra Archive Collection

 This collage displays eight different astronomical targets, each showcasing Chandra’s X‑ray data combined on images from telescopes sensitive to optical, infrared, or radio wavelengths. The 8 objects include the following: G266.2‑1.2 is a supernova remnant with purple X‑ray shocks over an optical background. 3C353 is giant double-lobed jets from a supermassive black hole seen in blue-purple X‑ray and orange radio. NGC 3576 contains a glowing nebula lit by young stars, with blue X‑ray and yellow/orange optical. NGC 4945 shows an edge-on galaxy with an active black hole, blue X‑ray atop optical detail.  IC 1396A is the “Elephant Trunk Nebula,” blending purple X‑ray, visible, and infrared tones. 3C 397 looks like a box-shaped supernova remnant in purple X‑ray, optical, and infrared.  SNR B0049‑73.6 is a supernova in the Small Magellanic Cloud, with purple X‑ray plus infrared in yellow. NGC 6946 is called the “Fireworks Galaxy,” and is a spiral with purple X‑ray highlighting ancient supernovae over optical data.  This montage beautifully illustrates the power of multiwavelength astronomy. By overlaying Chandra's X-ray vision (which reveals high-energy processes like supernova shocks, black hole jets, and hot stellar winds) onto optical and other light, each composite deepens our understanding of cosmic phenomena—from the death throes of stars to the energetic cores of galaxies—while also delivering stunning visuals.
