 Abstract:

Nebulae and Black holes emit X-ray when the material is accelerated and heated to very high temperatures. The present work focuses of composition of nebulae and black holes. Data were obtained through space telescope spectroscopy at X-ray wavelength from Chandra space telescope and by use DS9 software to analyze spectra that have been collected from Chandra. The results of present work showed a relation between photon count and energy for three Nebulae (NGC 2392, NGC 6826 and NGC 7009) and three Black holes (M82ULX, RXJ1131 and sgrA*).Both of Black holes and Nebulae observed with Chandra X-ray observatory, and ACIS spectrometer in the energy range (100-10000) eV. Many different elements was founded in these objects, we found that the carbonis most abundant element in the universe.
