Why on Earth could this be? is there somehting visible occurring on Sirius which google does not wish us to see? Or is this a simple missing piece of data? Unlikely the last possibility, due to the fact that the beige colored space used to blank the star out lets you see that the image quality of the outer perimeter and rays of Sirius are crystal clear, and therefore proves that the image should be there. It has obviously been deliberately covered for some elusive reason. It appears that we now need assistance from avid astronomers who posess adequate equipment to obtain astronomical photographs of the vicinity around the Dog Star Sirius, so that we can examine and see what findings are to be discovered, if any.

Strange anomaly of Sirius disappearing
Secret Sun Above Top Secret - Sirius Censored in Google Sky
After serious searching i found an amateur picture of Sirius made in December 2009, unfortunately it is too small to observe any magnification of possible events which may be occurring on Sirius.
So that was the bad news... Now here's the good news;
I continued probing and noticed that there was some strange looking anomalous object to the top right of Sirius in the picture, and magnified it - and here is what it looks like!
and lets have a look inside...
