The Radcliffe Wave next to our Sun (yellow dot), inside a cartoon model of the Milky Way. Blue dots are clusters of baby stars. The white line is a theoretical model by Konietzka et al. that explains the current shape and motion of the wave. The magenta and green lines show how the wave will move in the future.

This Hubble image shows NGC 1841, a globular cluster some 162,000 light-years away in the constellation of Mensa. The color image includes ultraviolet, optical and near-infrared observations from both Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
