Gold Foil Spacecraft — 3 museum-grade prints in this palette. Swift revolutionized gamma-ray burst science by proving that rapid multi-wavelength follow-up could turn transient alerts into detailed astrophysical investigations within minutes. The mission confirmed that long-duration bursts arise from massive star deaths and that short bursts trace neutron star collisions — a connection validated when LIGO detected GW170817 alongside Swift's X-ray afterglow. New Horizons captured the first close images of Pluto on 14 July 2015, transforming a blurry Hubble smudge into a geologically complex world with nitrogen glaciers and a heart-shaped plain named Tombaugh Regio. The mission holds the record for fastest launch velocity from Earth and demonstrated that small RTG-powered probes can deliver flagship science across decades. The Fermi Gamma-ray Space Telescope transformed high-energy astrophysics by producing the most detailed gamma-ray sky map ever assembled. Its 2010 discovery of the Fermi bubbles — enormous structures of hot gas and cosmic rays emanating from the Milky Way's core — challenged models of Galactic evolution and supermassive black hole feedback.
