ROSAT All-Sky Survey (X-ray)

March 17, 2003
This image of the entire sky is from the ROSAT All-Sky Survey. The survey was completed during the first 1/2 year (1990-91) of the ROSAT Mission. The data, 0.1 - 2.0 keV, have been exposure corrected but not cleaned of contamination. The strong striping of the data is an artifact of the contamination and is caused by several processes. Solar X-rays scattered by the residual atmosphere along the line of sight are a major contributor.
