This NASA/ESA Hubble Space Telescope image of the spiral galaxy NGC 1637 is scattered with evidence of star formation ⭐ if you know where to look! The galaxy’s spiral arms are dotted with what appear to be pink clouds, many of which are accompanied by bright blue stars. The pink comes from hydrogen atoms excited by ultraviolet light from young, massive stars.

Let’s zoom in to one of the largest spiral galaxies ever seen, UGC 2885. We look across 232 million light-years of space to see the full expanse of the galaxy, which is over two times the width of our Milky Way galaxy and contains at least 1 trillion stars. The galaxy has been nicknamed Rubin's galaxy, after the late astronomer Vera Rubin, who used the galaxy to look for invisible dark matter. The galaxy is embedded inside a vast halo of dark matter. The @VRubinObs is also named in her honor. Cr
