The astronomers well understand that cooling sensors results in both less noise 
and less signal 
decay. See 
http://www.astrophys-assist.com/educate/noise/noise.htm and 
http://www.andor-tech.com/library/digital_Cameras/index.asp?app=316

They have a variety of ways of post processing to reduce noise.
