The cos­mic cat and the sil­ver space­craft

All About Space - - Launch Pad -

NASA’s Spitzer Space Tele­scope has a canny set of in­stru­ments that can view many things in a light in­vis­i­ble to our eyes: in­frared emis­sion. Us­ing its pow­ers of heat sur­veil­lance, it im­ages the fa­mous ne­bula NGC 6334 also known as the Cat’s Paw Ne­bula.

The con­cen­tra­tions of gas in this im­age are where stars are born, and they il­lu­mi­nate sur­round­ing dust to present the pink-red fea­tures. The green frame of the ne­bula is where the stel­lar ra­di­a­tion strikes large mol­e­cules, known as poly­cyclic aro­matic hy­dro­car­bons.
