  • A. COBE Differential Microwave Radiometer experiment
    The COBE Differential Microwave Radiometer experiment was a space-based instrument that precisely measured tiny temperature fluctuations in the cosmic microwave background, providing key evidence for the Big Bang theory and the large-scale structure of the universe.
  • B. Cosmic Background Explorer
    The Cosmic Background Explorer (COBE) was a NASA satellite mission that made precise measurements of the cosmic microwave background radiation, providing key evidence for the Big Bang theory and earning its scientists the Nobel Prize in Physics.
  • C. Infrared Astronomical Satellite
    The Infrared Astronomical Satellite (IRAS) was a pioneering space telescope launched in 1983 that conducted the first-ever all-sky survey at infrared wavelengths, dramatically expanding knowledge of stars, galaxies, and cosmic dust.
  • D. Faint Object Camera
    The Faint Object Camera was a high-resolution imaging instrument on the Hubble Space Telescope designed to observe very dim and distant astronomical objects in ultraviolet and visible light.
  • E. Compton Gamma Ray Observatory
    The Compton Gamma Ray Observatory was a NASA space telescope dedicated to observing high-energy gamma-ray emissions from cosmic sources, significantly advancing our understanding of phenomena like gamma-ray bursts, pulsars, and active galactic nuclei.
