The Hubble Telescope.

The Hubble Telescope.
The Hubble is a telescope that has been on the space for the last 20 years, this telescope was an idea of Edwin Hubble an American astronomer very important for hisdemonstrations of the existence of galaxies other than our own, the Hubble it’s still under operation and have been taken an important role on the subject, at first when the astronomers try to get images itdidn’t work properly, even when the primary mirror was polished for with really carful for a hole year, it had a flaw called "spherical aberration." To resume the image was blur and after make a fewadjustments as the incorporation of new lenses the image then get better and was possible the correct view of other galaxies and the rest of the space, thanks to these and the internet the imagestook up there, can be seen down here.
The Hubble is the most successful and long lasting science mission, it has sent hundreds of thousand pictures down to earth and help on the discover of the earthage, before the Hubble scientist and people used to think that the universe was 10 0r 20 billion years old but it was wrong and the real age is proximally from 13000 to 14000 years old.
The Hubblegoes around the planet earth in approximately each 27 minutes on a velocity of 5 miles per second, his primary vision is with a little mirror which diameter is 2.4 meters; the energy that Hubble used isthe sun with 2 solar panels of 25-foot; the telescope was launch at 1990 and it has a cost of 1.5 billions of dollars, his size is almost as a large school bus.
The Hubble take pictures of theuniverse and different galaxies, the galaxies are enormous accumulations of stars, gases and powder, in the Universe there are hundreds of thousands of millions. Every galaxy can be formed by hundreds ofthousands of million stars and other stars in the center of the galaxies it is where more stars are.
The nebulas are seen by the Hubble those are interstellar cloud of dust, hydrogen gas, helium gas...
