Suzaku’s energy resolution and angular resolution were even more advanced than those of ASCA. It carries a soft-X-ray telescope and a highly sensitive hard-X-ray detector so it can observe spectra over a wide range in energy.
Its major achievements to date include the observation of the composition of carbon in normal stars and planetary nebula, and the discovery of rare metals in a galaxy cluster that told the history of element composition from a star to a supernova explosion. Suzaku also discovered a black hole covered by thick gas and dust in a galaxy cluster, and observed that explosive phenomena occur in the middle of the Milky Way galaxy. It has performed research on high-energy phenomena in the universe, and found evidence of particle acceleration in a supernova remnant. It is still performing observations, and more achievements are anticipated in the future.
