This is a simulation of 360º night sky of past 400000 years plotting 0.9 billion stars from GAIA DR2 and Hipparcos Catalogues.
You can see moving open clusters such as Hyades and Pleiades, and in-plane and out-of-plane motions of stars from milky way. I recommend to see the directions of Orion and Taurus constellations (right side of the original direction).

Data from GAIA DR2 and Hipparcos-2 catalogues with colors and positive parallaxes are shown. Radial velocity is from GAIA DR2 and Hipparcos input catalogues. The overall size and brightness of each star is proportional to the brightness of the stars. Colors are also realistically calculated from effective temperatures assuming black body radiation. When Teff is not available from GAIA DR2, relations between B-V or BP-RP and Teff are approximated and used. Stars without BP-RP or B-V are not shown.
