Just imagining will give you an idea that we are not very small criminality in the vast universe
The image shows a huge number of galaxies intercepted by Hubble.
Where we have modern methods of discovery and photography
There are two ways to detect outer planets
1-Or the most meteorological results are photometric arithmetic
To simplify them we can represent them
By measuring the light of a star and passing a planet with less illumination
Then he returns to know the existence of a planet
2 - either direct imaging via ultraviolet or infrared waves with the work of the
industrial eclipse of the star
The strangest human discoveries are black holes, great energy, strong gravity.
The greatest mysteries of space are the dark matter, the unknown space and the mysterious composition ...
The sunspot with the number AR2738 extended to about 200,000 km and incidentally from the surface of the sun
This black zone has a temperature of about 4500 degrees
In the vicinity of a temperature of 6,500 degrees
The temperature difference is black
If we put the spot alone in space we would see it as a radiant star.
And a close-up of a solar spot on the surface of the sun
The features of the surface of the sun, called (grain)
