This Hubble image shows NGC 1755, an open star cluster some 160,000 light-years away in the southern constellation of Dorado. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

All-sky map of the Milky Way in motion using the Gaia data. Areas with significant motion are shown in black/purple and those with relatively low motion in yellow. A number of large scale filamentary disc structures are evident about the midplane. The map also shows the Magellanic Clouds and their connecting stellar bridge to left, while the Sagittarius dwarf galaxy currently being torn apart can be seen on the right (main body).

This Hubble image shows NGC 3568, a barred spiral galaxy some 57 million light-years away in the constellation of Centaurus. The color image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) instruments in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through three filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.
