Here is a great image of Sirius AND Sirius B, its small companion star, as taken by Hubble:
This Hubble Space Telescope image shows Sirius A, the brightest star in our nighttime sky, along with its faint, tiny stellar companion, Sirius B.
Astronomers overexposed the image of Sirius A [at centre] so that the dim Sirius B [tiny dot at lower left] could be seen. The cross-shaped
diffraction spikes and concentric rings around Sirius A, and the small ring around Sirius B, are artifacts produced within the telescope’s imaging
system. The two stars revolve around each other every 50 years. Sirius A, only 8.6 light-years from Earth, is the fifth closest star system

but what we're looking for is an up to date image.
I don't know when that image was taken.
google earth imagery is constantly updated.
the sirius censor/graphic artifact has been that way for two years.
if you look at sirius in the night sky, it's the most interesting star (to me at least) because it flashes like a siren light red and green
i've never noticed it do this before recent months.
i just want to see a very new image of it.
guess we'll leave it up to our fellow amateur astronomers with their telescopes to snap a few recent pics and post them.
and by recent i mean now.
and yeah.. it's the same artifact image in all the major sky viewing software packages.. maybe they get their image from the same source?
