Mark Godwin captured an extraordinary image of the ISS crossing the Sun on July 27, 2024, at 15:24:46 UT using his new ZWO Seestar S50 Smart telescope. The impressive still was extracted from a 4-second video sequence….

Multiple milestones in astronomy have reshaped our understanding of the universe: from Apollo 8’s Earthrise photo to Copernicus’ heliocentric model, Galileo’s observations, Hubble’s expanding universe, and Penrose’s cyclic cosmology theory….

Dean Ashton discusses his two-month exploration of a new approach in PixInsight for comet processing, combining the PI Comet Alignment and StarNet2 processes. He explains his workflow and details the composition and colors of various comets captured with a Nikon Z6 camera….
