Abstract

COBE has produced significant new scientific findings and results in the past year. The DMR instrument reported detections of temperature fluctuations in the cosmic microwave background (CMB) radiation. The DMR data are consistent with power law spectrum of Gaussian initial fluctuations with the quadrupole-normalized amplitude of Qrms–PS = 17±3 μK and a power law index n = 1.1 ± 0.6. These data are supportive of models of structure formation through gravitational instability.

The FIRAS instrument results improved indicating that the spectrum of the cosmic microwave background deviates from a Planckian spectrum by less than one part in 3000 of the peak intensity over the wavelength range 0.05 to 5 mm. These data rule out a number of alternative models of structure formation including explosive scenarios.

The initial COBE data products, in particular the first year DMR sky maps, were released to the scientific community in June 1993.

The National Aeronautics and Space Administration/Goddard Space Flight Center (NASA/GSFC) is responsible for the design, development, and operation of the Cosmic Background Explorer (LOBE). Scientific guidance is provided by the LOBE Science Working Group.
