Summary

Description
English: Temperature of the Cosmic Microwave Background (CMB) radiation spectrum as determined with the COBE satellite during the first two years of the Differential Microwave Radiometer (DMR) observation. The plane of the Milky Way Galaxy is horizontal across the middle of each picture.

In this map, the dipole due to the solar system movement has been removed, as well as the radiation of our own galaxy.

Note: This map is based on data collected over the two first years of the four-year COBE mission. Therefore, it has been superseded by the four-year map.
Date Data collected between 1990 and 1992.
Source
Author The COBE datasets were developed by the NASA Goddard Space Flight Center under the guidance of the COBE Science Working Group.
