Top view of the Milky Way showing the estimated orbits of both our Sun and 3I/ATLAS. The comet is shown in red dashed lines, and the Sun is shown in yellow dotted lines. The large extent of the comet’s orbit into the outer thick disk is clear, while the Sun stays nearer the core of the Galaxy. Image credit: M.

This Hubble image shows Abell 209, a galaxy cluster located about 2.8 billion light-years away in the constellation of Cetus. The color image includes both optical and infrared observations from Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). Twelve filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / M. Postman / P. Kelly.
