COMMENTS ON THE PHOTO:
NGC 4565 (or CaldWell 38) is a vast barred spiral galaxy, seen from the edge and located in the constellation of the Chevelure de Bérècine. It is also known as the Needle Galaxy because of its narrow profile, and its central bulge is domed and square.
It was discovered by William Herschel in 1785.
Its distance from Earth is approximately 43 million light-years.
Its estimated diameter is identical to that of the Milky Way (about 100,000 light-years).
