-
A.
Cosmic Background Explorer
chosen
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.
-
B.
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.
-
C.
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.
-
D.
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.
-
E.
International Ultraviolet Explorer
The International Ultraviolet Explorer was a space telescope launched in 1978 that provided pioneering ultraviolet observations of astronomical objects for nearly two decades.
- F. None of above.
