Hubble captures the sharpest ever view of Andromeda Galaxy
I've looked at the zommable picture. When I zoomed to the maximum, I saw a lot of noise in the picture (and a arather regular one). Does it mean that although the resolution is pretty impressive, the noise make it less "useful" ? Just asking, I've 0 knowledge in this area.<p>Second question, just out of curiosity, would it be possible to look at closer objects like Mars or the moon ? We'd have a pretty good image too ?
