It explains why the image is so grainy. At first I was confused what that stripe to the left and the bottom was. But it’s just the window edge, and the noise isn’t stars.
Well one of them is obviously Venus. How did you determine the others weren't stars?
(To be clear, the bright dots are stars [except the brightest one, in the lower right, is Venus I think], which makes this photo also a great demonstration that of course you can capture stars in space, you just have to expose properly!)
