In November 1989, NASA launched the Cosmic Background Explorer (COBE) satellite. During the duration of its flight, the three instruments onboard COBE (FIRAS, DMR and DIRBE) will be mapping the sky at wavelengths from 1 mm to 1 cm with the fundamental missions of: (1) making precise measurements of the spectrum and of the large scale anisotropy of the Cosmic Microwave Background (CMB) back in redshift to z ≡ 106 or t ≡ 1 year, (2) detecting a possible Cosmic Infrared Background (CIB) due to the cumulative emissions of objects formed since the decoupling of matter and radiation (z ≡ 103 or t ≡ 104years) and (3) studying the large scale infrared and submillimeter emissions of the Galaxy. First, the author briefly reviews the status of the Cosmic Background Radiation (CBR) before COBE; then, the first results of COBE are summarized and their preliminary implications on Superconducting Cosmic Strings (SCS) are presented. Finally, the author gives a brief insight into the future of the COBE mission.
