M83 is a barred spiral galaxy in the Hydra constellation, around 15 million light years from earth.
Because of its relatively large size in our night sky and high apparent magnitude; it was one of the earliest galaxies to be discovered. When observing this galaxy, it has what's called a double nucleus. It appears to have two individual cores sitting right next to each other. So what's going on there?
For starters let me state that double nucleus galaxies aren't all that uncommon. We basically find them all over the universe. We believe there's two possible explanations for why this phenomenon exists:
1) Galactic mergers. When two galaxies collide, they'll eventually (it's a slow process) merge into a single entity. Obviously, there'll also be two galactic cores/nuclei that end up merging. The dual nucleus may simply be just that.
2) Whenever there's something strange going on near the center/core of a galaxy; the number one culprit on everyone's list will usually be the supermassive black hole present there (and with good reason). Said black hole will of course have a significant gravitational impact all throughout the central region of its galaxy. Another possible explanation for the double nucleus suggests that depending on the type of material being present around the black hole (stars, gas/dust,...); the angle/tilt of the resulting disk/trail might differ. This will create a sort of illusion of two different nuclei.

En la constelación de Hydra se puede encontrar una espectacular galaxia espiral. Esta es M83, la Galaxia Molinillo del Sur. Obtuvo su nombre por la distinta forma de molinete de sus largos brazos en espiral. Las imágenes en color de esta galaxia revelan una amplia gama de colores, desde el núcleo central amarillo de las estrellas viejas hasta los brazos espirales azules de las estrellas jóvenes. También se pueden ver varios nudos rojos. Estas son nebulosas gaseosas donde se está produciendo una formación estelar activa. Las líneas oscuras de polvo también son visibles en todo el disco de la galaxia. M83 está situado a unos 15 millones de años luz de la Tierra. Se aleja de nosotros a unos 337 km / seg. Esta galaxia ha sido el sitio de seis supernovas, que es más que cualquier otra galaxia Messier. También fue la primera galaxia en ser descubierta más allá del Grupo Local.

In the constellation Hydra can be found a spectacular spiral galaxy. This is M83, the Southern Pinwheel Galaxy. It earned its name from the distinct pinwheel shape of its long spiral arms. Color images of this galaxy reveal a wide range of colors from the yellow central core of old stars to the blue spiral arms of young stars. Several red knots can also be seen These are gaseous nebulae where active star formation is taking place. Dark lanes of dust are also visible throughout the galaxy's disk. M83 is situated about 15 million light years from Earth. It is receding from us at around 337 km/sec. This galaxy has been the site of six supernovae, which is more than any other Messier galaxy. It was also the first galaxy to be discovered beyond the Local Group.

They say I made the moon
Everything was in the dark
No memories at all
Just a tiny freezing wind in my back
As I was sitting there
Singing a song they had never heard before
Suddenly, a voice told me
"Keep on singing, little boy
And raise your arms in the big black sky
Raise your arms the highest you can
So the whole universe will glow"
My first vision was a bush growing down the river
And I couldn't stop crying
Something was missing
I realized I was in love with a voice
I called it, again, and again
But all I heard was the echo in the light

Messier 83, also known as the Southern Pinwheel Galaxy, is a barred spiral galaxy approximately 15 million light-years away in the constellation borders of Hydra and Centaurus. Nicolas-Louis de Lacaille discovered M83 on 23 February 1752 at the Cape of Good Hope. It is one of the closest and brightest barred spiral galaxies in the sky.Its nickname of the Southern Pinwheel derives from its resemblance to the Pinwheel Galaxy M101.

JANUARY 9, 2014: The vibrant magentas and blues in this Hubble image of the barred spiral galaxy M83 reveal that the galaxy is ablaze with star formation. The galactic panorama unveils a tapestry of the drama of stellar birth and death. The galaxy, also known as the Southern Pinwheel, lies 15 million light-years away in the constellation Hydra.

I wrote a 14 page essay on this album. I received an 'A' for my efforts. Thank you Anthony Gonzalez.
M83 is a barred-spiral galaxy in the direction of Hydra, 15 million light years away and about 55,000 light years across. It is a starburst galaxy and unusually, six supernovae have been observed in it in the last 100 years.
It was one of the first deep sky images I attempted almost 10 years ago. Although it was a reasonable effort, recently I felt it worthwhile to have another go since I've learned so much about the equipment and image processing over that time. Here is the result from data collected on the 21st February.

I'm very pleased with the result.

M83 is in the Southern constellation Hydra, and is sometimes called the Southern Pinwheel. It's about 100,000 LY in diameter and about 13 MLY away from us, fairly close by galactic standards. From most of the US it is low on the horizon, and therefore difficult to photograph. The blue areas are new, hot stars. The yellow-gold areas are older, cooler stars mixed with dust. The pink areas are hydrogen clouds forming nebulas and giving birth to new stars.
This image was taken in Southern New Mexico, at Rusty's RV Ranch, through the generosity of Rick Needham.

Attempt to capture M83. Too bad the telescope was decollimated and the field flattener didn't work properly. The electronic filter wheel didn't want to work either. So I couldn't make a color image.

Gran, brillante y hermosa, la galaxia espiral M83 yace a unos 12 millones de años luz de distancia, cerca del cuadrante sureste de la gran constelación de la Hidra.
Sus prominentes brazos espirales de oscuros caminos de polvo y azulados cúmulos de estrellas, dan a esta galaxia su popular nombre de Molino del Sur.
Con una longitud de unos 40.000 años luz, M83 es miembro de un grupo de galaxias que incluyen a la activa galaxia Centauro A.
El corazón de M83 como tal es brillante en energias de rayos X, mostrando una alta concentración de estrellas de neutrones y agujeros negros de un intenso estallido de formación estelar.

M83 is also known as the Southern Pinwheel Galaxy due to some resemblance to M101, the actual pinwheel galaxy. M83 is located at the border of the constellations Hydra and Centaurus and is about 15 million light years away. At my location, the object barely rose to 25 degrees above the horizon making this a challenging object to capture and process from the northern hemisphere, since the atmosphere is about 40 times thicker at the horizon as it is looking straight up. so at 25 degrees above the horizon, the atmospheric disturbances cause the image to lose a lot of detail.
The Southern Pinwheel - M83 is a lovely, flat-on, bared galaxy residing in the constellation of Hydra.
This galaxy was taken with a Takahashi FS-128 mm refractor with a QSI 583 camera and Astrodon LRGB filters.

The spiral galaxy M83 lies a mere twelve million light-years away, near the southeastern tip of the very long constellation Hydra. Prominent spiral arms traced by dark dust lanes and blue star clusters lend this galaxy its popular name, The Southern Pinwheel. ... M83 is a member of a group of galaxies that includes active galaxy Centaurus A. In fact, the core of M83 itself is bright at x-ray energies, showing a high concentration of neutron stars and black holes left from an intense burst of star formation. {NASA APOD 2019).
