Observing our universe in different kinds of light 🌌
Each of these images combines data from our @NASAChandraXray observatory with data from other missions. This "multiwavelength" approach to astronomy helps us get a more complete understanding of objects in space.
1. This Helix Nebula image contains infrared data from our Spitzer Space Telescope (green and red), optical light from our @NASAHubble Space Telescope (orange and blue), ultraviolet from ours Galaxy Evolution Explorer (cyan), and Chandra's X-rays (appearing as white) showing the white dwarf star that formed in the center of the nebula. The image is about four light years across.

2. The Cartwheel Galaxy resembles a bull's eye, which is appropriate because its appearance is partly due to a smaller galaxy that passed through the middle of this object. X-rays from Chandra (purple) show disturbed hot gas initially hosted by the Cartwheel galaxy being dragged over more than 150,000 light years by the collision. Optical data from Hubble (red, green, and blue) show where this collision may have triggered the star formation.

3. Eta Carinae is a volatile system containing two massive stars that closely orbit each other. This image has three types of light: optical data from Hubble (appearing as white), ultraviolet (cyan) from Hubble, and X-rays from Chandra (appearing as purple emission).

4. Supernova 1987A (SN 1987A) in the Large Magellanic Cloud was one of the brightest supernova explosions in centuries. The Chandra data (blue) show the location of the supernova's shock wave interacting with the surrounding material about four light years from the original explosion point. Optical data from Hubble (orange and red) also shows evidence for this interaction in the ring.
