This composite image of the planetary nebula IC 4593 contains X-rays (Chandra) from gas that has been heated to over a million degrees. These high temperatures were likely generated by material that blew away from the shrunken core of the star and crashed into gas that had previously been ejected by the star. Visible light data from Hubble in the image show combinations of nitrogen, oxygen, and hydrogen. Image credit: NASA / CXC / UNAM / J. Toala et al. / STScI.
