Embark on a celestial journey with SpaceTime Series 27 Episode 51, as we unravel the mysteries of Pluto's heart. Scientists, armed with sophisticated computer simulations, have finally pieced together the enigmatic origins of the dwarf planet's heart-shaped feature, Sputnik Planitia. This episode delves into the colossal impact that sculpted Pluto's icy facade, challenging previous assumptions about its internal structure and the existence of a subsurface ocean. The cosmic surprises continue as we delve into the perplexing absence of gamma rays from a recent supernova explosion in the Pinwheel Galaxy. SN 2023 IXF's silent gamma-ray profile has left astronomers scratching their heads, prompting a reevaluation of the role supernovae play in accelerating cosmic rays to near-light speeds. Witness the end of an era with the final launch of a Delta rocket, a titan of the space industry for over six decades. The Delta IV Heavy's last ascent, carrying a classified payload for the National Reconnaissance Office, marks a historic milestone and paves the way for the next generation of launch vehicles. And in our Science Report, we explore the alarming rise in global obesity rates, the benefits of resistant starch in diets, the development of an automated toilet flushing device to combat bathroom bacteria, and a curious survey on the belief in angels.
