This episode breaks down Jamie Bock’s latest update on SPHEREx — NASA’s all-sky spectroscopic mission now completing its first full-sky survey after launching in March. SPHEREx isn’t another imaging satellite. It’s a 20-cm cosmology machine in low-Earth orbit, scanning the entire sky in hundreds of infrared colors to probe: The physics of cosmic inflation 🌀 The formation of galaxies across cosmic time 🌌 The distribution of water ice in the interstellar medium ❄️ And even the evolution of the interstellar visitor 3I/ATLAS, now under intense study Jamie shares early results, including fresh observations of the Cat’s Eye Nebula and the mission’s first spectra of 3I/ATLAS. With full public data releases coming just two months after collection, SPHEREx is poised to become one of the most scientifically disruptive missions of the decade. In this video, you’ll learn: Why SPHEREx’s scanning strategy and spectroscopic resolution matter How its data will enable power spectra, clustering analyses, and bispectrum probes What we can expect from the December follow-up observations of 3I/ATLAS Why mapping 20,000+ icy objects could reshape our understanding of planet formation How the SPHEREx team is preparing redshift catalogs, deep-field masks, and cross-correlations with galaxy surveys If you want a front-row seat to the next wave of cosmological discovery, this update from the SPHEREx team is essential.
