Present status of x-ray astronomy is overviewed basing on recent observational results obtained with Hakucho, Tenma and Ginga. The high sensitivity of Ginga revealed hard x-ray emission from various class of x-ray sources such as premain sequence stars, dark clouds, supernova remnant, diffuse Galactic component, galaxies and QSOs. The data with less Poisonian noise and improved method of analysis have been clarifying chaotic variations of x-ray intensity from Galactic annd extra-galactic compact sources, in ralation to structure of accretion disc. Future project on spectroscopic x-ray observatory is briefly presented.
