Photography allows us to see beyond our Atmosphere, it makes it possible to explore areas far away from us thousands or millions of light years.
Observing or Photographing space, its mysteries and its beauty, is a journey in search of our existence.
To stimulate the curiosity of those who do overlooking this site I try to make a quick representation of what in theory it was the evolution that led to the formation of Planet Earth.
​
We will take a trip aboard the Comet LoveJoy

We all consider history important, it teaches us things ......., the history of the universe has the beauty of 14 billion years.
Before the Big Bang there was a small source of energy, a region of extremely compact and dense matter.
Explosion and nucleosynthesis
primordial responsible for the formation of: hydrogen, its deuterium isotope, helium isotopes, lithium isotope.
Isotope, Atom of the same chemical element (same atomic number) but with different atomic mass number.
Matter and anti-matter after the Big Bang
The two elements conflict with each other, being matter
present in greater quantities has the upper hand over antimatter,
this allowed what we see today.
Extremely high temperatures, expanding universe, massive presence of gas.
And now Gravity comes into play, it is thanks to it that things have evolved .
The miracle of gravity, if gravity had been in a state of perfect balance there
mass of atomic gas would not be never thickened, consequently neither the galaxies nor the stars
They would have originated.
Example of perfect balance
Fortunately, there were gaps in this enormous concentration of atomic powders, mainly hydrogen, this allowed the subsequent aggregation due to scattered centers of gravity.
Matter it starts to aggregate in no particular order, Galaxies are formed, they start Stars
Compacting of Hydrogen, in this phase the atoms overturn each other
generating a sharp increase in pressure and temperature, it triggers the Thermo Nuclear fusion, the Star lights up, in this phase the Hydrogen melts into Helium and the star is stable.
The first stars are born
The universe takes shape
The Stars, the essence of our existence, also have a more or less long life, their end can occur with an explosion in Supernova or through expulsion of Gas which will lead to the formation of a Nebula Planetary with at the center what remains of the star that generated it, a Nana White.
The photos you will see on the site contain images of both Supernovae and Planetary Nebulae, other images portray galaxies up to 400 million light years away, you will encounter diffuse Nebulae, still areas densely charged with Hydrogen within which new Stars come to life, as I said the photograph of these mysterious and distant places immersed in Deep Space tells our story of Yesterday Today and Tomorrow, for example how the end of our Sun could happen .
Nuclear fusion inside the Stars generates oxygen, carbon
(basic element for our existence), iron.
Of all the elements that are produced during nuclear fusion that keeps a Star alive Iron is the heaviest and lowest energy element, it is generated by the transformation of helium concentrated in the center of the Sun as a residue from the fusion of hydrogen, Helium which is deposited in iron, an element that absorbs energy making it with the passage of time the star unstable.
Thus the Star gradually approaches the end.
The Iron present in too high quantities in the center of the Sun creates a stronger center of gravity than the Gravity outside the Star together with the lack of hydrogen consumed with the weather it starts to a slow end. An end that will also happen for our Star in 5,000,000,000 years.
The end of the star leads to a very violent explosion called SuperNova as a consequence of the death of a super massive star, or planetary Nebula for a Star similar to our Sun.
Graphic representation of the universe in clusters of galaxies
The Universe is constantly expanding, the galaxies within it generally move away from each other and only some come close to each other, one of these is Andromeda that you will see in the picture, this Galaxy is approaching ours and in 2/3 billion years the junction will take place.

Measurement order.
Light travels at 300,000 km per sec.
The objects that you will see taken back pass by a few hundred, myiaia of years light up to 400 million light years.
Sunlight takes 8 minutes to reach the Earth.
​
How the photos are taken:
The shots are obtained with summed poses ranging from 4 to 9 hours.
The sensor is a CCD contained inside a sealed chamber and has a Delta-e Thermal of -50 ° compared to the ambient temperature (if the ambient temperature is 0 °, use a delta_E of -20 ° at most, while if the external temperature is 30 °, as can happen in Summer, I use the maximum cooling power of the sensor) the CCD is in Black and White as it is more sensitive to light (it helps to capture the very faint light photons arriving from space) being devoid of the Bayer matrix, R, G, B colored glass filters are used for the Colors, while to cut the light pollution of the Countries / Cities / Po Valley, glass interference filters, CLS, Halpha, Hbeta, are used. OIII.
Glass filters have a high degree of transparency unlike the Bayer matrix.
Many years ago it was calculated that there were about 200 billion galaxies but the latest data obtained actually came to the count of 2000 billion galaxies in the universe, the one in which we are immersed ..... and for each galaxy it is calculated an average of 300 Billion Stars.
