😉 NGC3242, a planetary #nebula, that have been observed both by @Chandra X-ray Observatory (X-rays in magenta colour) and Hubble Space Telescope (optical in red, green & blue colours) space telescopes.

📖 #Planetary nebulas are a phase that #stars like the #Sun undergo after they run out of nuclear fuel (as the Sun will billions of years from now). X-rays reveal the hottest and most energetic processes, including #shock waves created by rapid winds from the star colliding with slower-moving material that has previously been ejected by the star.

🤓 Chandra’s exceptional #vision in X-rays contributes to the understanding of this brief, yet important, stage of stars’ lives.
