We present results from the observation of the supernova remnant (SNR) G1.9 + 0.3, which is the youngest known SNR in the Milky Way, with the X-ray imaging spectrometer (XIS) on board Suzaku. We investigate the nature of the X-ray emission and compare our results with the previous X-ray studies. Additionally, we present the analysis results of the GeV gamma-ray data taken for about 6 years by the Large Area Telescope on board Fermi and discuss these results in the framework of existing gamma-ray emission scenarios.
