Not funny to try to imagine that white blob is NOT a white blob, it's many suns, when you zoom far in.
The only way to zoom way in, is to use your imagination.
Being a human, we have that skill, ⭕it's 200,000 lyr in diameter

NGC 772 (also known as Arp 78 or the Fiddlehead Galaxy) is a large unbarred spiral galaxy approximately 106 million light-years away in the constellation Aries. It was discovered by German-British astronomer William Herschel on 29 November 1785.

At around 200,000 light years in diameter, NGC 772 is somewhat larger than the Milky Way Galaxy and is surrounded by several satellite galaxies – including the dwarf elliptical, NGC 770 – whose tidal forces on the larger galaxy have likely caused the emergence of a single elongated outer spiral arm that is much more developed and stronger than the others arms. Halton Arp includes NGC 772 in his Atlas of Peculiar Galaxies as Arp 78, where it is described as a "Spiral galaxy with a small high-surface brightness companion".

NGC 772 probably has a H II nucleus, but it may be a transitional object.
