Very nice and impresive!

luigi.....

who do you take this tipe of photos? Are they computer generated? Stars in a telescope (even the rather big one) are only white, blue or red dots, and you get a tremendous amount of interference from the ozone layer, making them blurry. So how can it be in such detail?

These pictures were obtained by the Hubble Space Telescope, the Very Large Telescope and others telescopes. Of course, the space telescopes do not have any problem with the ozone layer. To obtain the color of any celestial object you must take images of the object in different bands and then compose them. As an example, the first picture is a H K L filter composite of the Galactic Centre region.

so they are several pictures putt together using normal and radio telescopes, using a computer to combind them to one image?
