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)

Gorgeous: The dark cloud Chamaeleon I holds pockets of starlight. Three reflection nebulae glow within its depths, reflecting light from new-born stars in one of Earth’s nearest stellar nurseries (Credit: CTIO/NOIRLab/DOE/NSF/AURA - T.A. Rector, M. Zamani & D. de Martin)

Spectacular: The inner region of NGC 247, a modest spiral galaxy roughly 11 million light-years distant in the constellation Cetus. NGC 247 is one of the Sculptor Group galaxies, which also includes the celebrated Sculptor Galaxy (NGC 253). (Credit: ESA/Hubble & NASA)

This spectacular spiral, Messier 96, lies 35 million light-years away, its lopsided arms and displaced core the hallmarks of gravitational encounters with galaxies close by. (Credit: ESA/Hubble & NASA and the LEGUS Team - Acknowledgement: R. Gendler)

Spectacular: High-altitude observation of the STS 51-A shuttle Discovery launch, with the pad shining as a central beacon in a cloud assembly; the Discovery shuttle is seen as a light at the pinnacle of a smoke shaft, bordered by dense cloud layers. (Credit: NASA)
