ALT we encounter an X-ray spectrum of the supernova remnant N132D in the Large Magellanic Cloud. The white spectrum from Resolve, exhibiting emission lines from various ions in the 1,800 -10,000 eV bandwidth, surpasses its predecessor, Suzaku, in separating previously indistinguishable lines. By dividing emission lines, the type and abundance of elements, the temperature and kinetic velocity of the high-temperature gas can be derived much more accurately than before. Resolve’s ultra-high resolution spectroscopic observations and impressive energy spectral accuracy below 5 eV, confirmed in orbit, set the stage for new insights into the Universe’s elemental formation and evolution, which are the basis of stars, planets, and life. Although Resolve’s spectra are still limited to 1,800 eV and above because the Dewar aperture door to protect the sensitive detector has yet to be opened, this band’s highest emission line sensitivity is evident.
