Hubble Space Telescope (HST)
Hubble Space Telescope (HST) - is a telescope which flies in cosmos, and takes pictures of most of other galaxies and planets. It basically is a huge digital camera. After it had left the Earth in 1990 April 24th, it started its journey by a spaceship, but when it got to the planned orbit, they separated and it began its own. The HST is much better than any other telescope that is used on Earth. The Earth’s telescopes can’t show the pictures very clear, and they always change. Because of the changes in the atmosphere, light from space might get blocked. However HST is one of a kind that is very far from our planet approximately 569 km above the surface, and can see everything clearly.
For a better observation the telescope has a 2.4-meter mirror. Some of the most important parts of the telescope are two cameras on both sides of the HST, so that it can take pictures, two solar panels- for getting energy and working properly, spectrograph- a device, which changes the colors, depending on how far the object is. Also two radio antennas, because of those it can send the signals to the Earth, and let us see the pictures, that it took.
From the beginning the optics of HST didn’t have any color, those were just shades of black and white, but after some operations made by astronauts, they put extra optics on the cameras, so after that they could see the colorful picture of most of the Galaxies. There are just a few objects which HST can’t see, they are the Sun (because it would destroy its sensors, since it is too bright) and Mercury, which is too close to the Sun. The evolution of the HST is extremely surprising. From the beginning, 1990 the telescope could only see for a very short, for the space, distance, however the distance became much greater in the past 20 years.
Some very interesting facts about Hubble Space Telescope, is that the length of this space object is about 13.2 m, and the weight is approximately 11,110 kg. The approximate speed of the telescope is 28.000 km/h. The first picture that was made by HST was The Star Cluster, on May 20th, 1990, which is 26 days after it was sent to Space. One of the most interesting facts about the telescope is that in 5 to 6 years, the Space Telescope will enter the Earth's surface, and will burn up in our atmosphere.
