The Hubble Space Telescope is in orbit for 25 years. At that time, it made countless photographs that have helped astronomers to better understand the nature of the universe. Here are few most spectular of them
The Hubble Space Telescope was launched on located approx. 570 km above the Earth's orbit on 24th April of 1990. This is a great achievement, because the telescope sent to this planet thousands of photographs. Some of them contributed to a better understanding of the nature of the universe, others made further questions.
Initially, the success of the Hubble Space Telescope was not obvious. Even after the elevation of the unit into orbit, it turned out that a mistake in grinding mirrors. Although the benefit concerned, mistakes of 4 microns (0.004 mm!), it meant that the telescope gave very blurry images. Rescue mission does not come right away. Only in 1993. Hubble was delivered to the lens COSTAR (Corrective Optics Space Telescope Axial Replacement), so that the image becomes clear, and it remains so to this day.
The Hubble Space Telescope is undoubtedly one of the most important devices in the history of astronomy. Within a few years it will go into retirement, and its tasks will take over the James Webb Space Telescope. Now he is in the testing phase, and will be launched into orbit in 2018. Until then, we can enjoy eyes incredible images sent by the Hubble Space Telescope.
Hubble Ultra-Deep Field
This is an image of a small area of sky in the constellation Fornax. Photo was in a series of 800 observations Hubble Space Telescope. At the time of publication (not shown before Extremely Hubble Deep Field) was the farthest reaching astronomical photograph that was made in visible light. Hubble Ultra-Deep Field shows the universe before 13 billion years, and contains approx. 10 000 galaxies.
Crab Nebula
Crab Nebula commonly assumed called supernova remnant, but this statement is inaccurate. For the power of the nebula corresponds to the central pulsar, a remnant of a star that exploded as a supernova ‘1054’. Pulsar rotates on its axis 30 times per second and emitting radiation ranging from radio waves to gamma. Travelling at the speed of light we would be able to reach Crab Nebula after 6,300 years
Sombrero Galaxy
The Sombrero Galaxy is a spiral galaxy located in the constellation Virgo, whose name comes from its appearance. The property has a big bright core, little developed spiral arms and partly to send her belt luminous matter. The galaxy contains many globular clusters that form a spherical halo around it.
Andromeda Galaxy
The best picture of our neighboring galaxy. Andromeda is a "home" for more than a trillion stars. In the picture you can see a hundred million stars over the 40,000 light-years. To get the effect that you see below, NASA made 411 photos, which later has been pu together in a cosmic mosaic. The picture size is 1.5 billion pixels (you are able to see whole picture by following this link).
NGC 3603
NGC 3603 is an open cluster in the constellation Carina, is approx. 22 500 light-years from Earth. To the formation of clusters bathed in the gas and dust happened approx. One million years ago. NGC 3603 spans over 1,000 light-years, but might be much weider.
The Pillars of Creation
It's definitely one of the most famous images taken by the Hubble Space Telescope. It shows the Eagle Nebula, which is in the distance of 7000 light years from Earth. The property is imperceptible to the naked eye but can be seen through binoculars.

Anyway one thing that comes to my mind that I can share is that last year astronomers discovered a really cool star that is made of diamond ;) You can read more about it here: http://www.dailymail.co.uk/sciencetech/article-2666534/Now-thats-precious-stone-Astronomers-spot-Earth-sized-star-DIAMOND.html
Beautiful presentation and photos :)
I'm currently reading Stephen Hawking's 'Universe in a nutshell'. If anyone's interested in the subject of universe's expansion, I'd recommend reading it. It also describes the methods used to determine the acceleration of the distant galaxies, which is very interesting.
Recently, NASA approved the concept of "Agaroscope" which might be build in near future.
Here is an article with more information about it!
