Dark Blue Solar Panels — 2 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. NuSTAR proved that hard X-ray astronomy could move beyond coded-aperture imaging to true focusing optics — a breakthrough that opened supernova element mapping, black hole spin measurement, and solar flare microphysics. The mission's first-light image of Cassiopeia A revealed titanium-44 emission, directly tracing the radioactive ashes of the explosion that created the remnant.
