NGC 7331
The NGC 7331 is a spiral galaxy in the constellation of Pegasus. It emits X-rays and radio waves. Discovered by W. Hershel in 1784. Although it is one of the brightest galaxies, he does not belong to the Messier list. The size and structure resembles our galaxy, so he called “the milky way’s twin." The look is reminiscent of the Andromeda galaxy. He seems inclined 71 degrees.
The galaxy has a central bulge that rotates in the opposite direction to the rest of the galaxy. Possibly due to infalling material (perhaps another galaxy). Another interesting fact is the discovery of a gas disk in the nucleus of the galaxy, but rotating faster than the galaxy's rotation rate. It is believed that this disk was formed relatively recently, before two billions years.
It is believed that at the center of the galaxy there is a black hole or a dense concentration of stars and this is the source of radio waves and X-rays emitted by the galaxy.

Skyros Island, Greece, September 2015
During my involvement in photographing the "deep sky" I missed the accompaniment of music, as my musical experience guides me. So I decided to fill my astrophotos with my music. From September 2016 as a starting point, therefore, together with the Flaming Star Nebula, I present to You, the ‘Floydish Pulsar I’, as my first musical composition (composition, performance and production by me), always inspired by these images.
Parallel Words ! and Dancing Stars I, complete my first trilogy.
Emjoy !
