From observations of distant galaxies light years
from us to the perception of invisible colors,
Adam Hedheyzi on BBC explains why your eyes can do incredible things. Take a
look around. What do you see? All these colors, the walls, the windows,
everything seems obvious, as it should be here. The idea that we all see it
because the particles of light - photons - that bounce off of objects and fall
into human vision, it seems incredible.

This picture was taken
with the Hubble Space Telescope agency NASA and ESA. It shows the dwarf galaxy
NGC 1140 is located 60 million light-years from Earth in the constellation
Eridanus. As seen in this image, the galaxy NGC 1140 has an irregular shape,
like the Large Magellanic Cloud - a small galaxy is a satellite of the Milky
Astronomers for the first time a more detailed look at the development time of normal galaxies succeeded. Observations of an international team of researchers with the radio telescope ALMA plant in the Chilean Atacama Desert show
fresh cool gas from
which new stars can form, apart from the central region of a young galaxy.

The research team from the University of Glasgow had physical evidence that could help find life on the Red Planet. Scientists have discovered that the Martian meteorite that fell near the Egyptian village of Nahla in 1911, contains traces of opal - precious stones, often used in jewelry. Material for the study provided the Museum of Natural History in London.
The two closest to the Earth planet - Mars and Venus - once had vast oceans, extending over many millions of square kilometers. But all the planets with liquid water on the surface is very fragile. Venus could not keep their oceans, and they vanished into space. Recently we learned that Mars lost most of their water, then it turned into a dry and cold desert.
Even if we have already told you about the mysteries of our solar system, here
, here and here , they
are innumerable, and we are back, taking in his arms even more mysterious
sights and features that confuse our scientists. Sometimes they even incite
conspiracy theories, and it adds even more fuel to the fire.
Mysterious "sounds" in space
The video above presents five mysterious "sounds" of the cosmos, three of which, of course, occurred in our solar system.

Discovered in 1930, we now know that Pluto is the brightest numerous swarm of small bodies that, as a second asteroid belt orbiting the sun beyond the planets. Are so far we know very little about them.
We know they are mostly ice, which are more like comets, asteroids and many short-period comets come from there. You will craters? Will rings? Will rivers of neon, nitrogen geysers? Will one meteorology, polar caps,
cryovolcanoes, underground seas?
