At first glance, a sky full of stars... Look closer: most of these tiny points of light are actually galaxies! This Rubin Observatory view captures around 10 million of them, each with a story to uncover. (Video by WorldAndScience - Credit: RubinObs/NOIRLab/SLAC/NSF/DOE/AURA)

At first glance, UGC 11397 appears to be a typical two-armed spiral galaxy. But after traveling 250 million years to our eyes, its light reveals a core dominated by a black hole of 174 million solar masses. (Credit: ESA/Hubble & NASA, M. J. Koss, A. J. Barth)
