ESA's Calender picture vs My picture
At first glance, this image (2nd image) looks nothing like the images that we are used to seeing from Hubble. It is suspected that in this case, Hubble had locked onto a bad guide star, potentially a double star or binary. This caused an error in the tracking system, resulting in this remarkable picture of brightly coloured stellar streaks.
A few weeks ago (its before than Hubbe's picture :) ) I took this photo (1st image) accidentally. Because, I shaked my camera at 4 seconds exposure mode (But I didn't share here). Yesterday I saw that Hubble did it too almost same thing. (But my colorful streaks are made of city lights, cars lights, buildings lights etc.)
So, which one is a better mistake? :)
