The Hubble Space Telescope is still in operation and was launched in the year 1990. It has four instruments that have the duties to observe in the near infrared spectra and the ultraviolet. It got its name after Edwin Hubble who was an astronomer in the USA. Its orbit around the atmosphere of the earth makes use of light that has a high resolution. The telescope has impacted the world of science significantly.
The ACS and STIS UV through their lights that are visible can be use to seeing the aurora of the south. Hubble has been able to solve many astronomy problems, and also has had its share of problems. There has been a greater need to provide new theories for purposes of explaining various results. It has been able to measure the distance to various stars and the expansion rate of the universe. It has been named to be more accurate compared to other used measurement tools.
Even thought it has been able to make measurements of the universe it has also raised the question that pertain its future. Different astronomers have successfully used the HST to see the supernovae which have led to the conclusion that the universe is expanding at a high rate. Dark energy is named as the cause of the rapid acceleration.
Through the high-resolution spectra, the HST can detect the presence of black holes in galaxies that are near. It was earlier anticipated that black holes were found in the middle of galaxies, but these theories were disputed. It however emerged that the different properties of the galaxies were closely related to the properties of the black holes.

The Hubble was also able to determine the collision dynamics of Jupiter with a comet in 1994. This was established after the full restoration of the Hubble’s performance in overall. Many other discoveries like that of the proplyds were possible through the HST. This brought about the realization of the existence of extra solar planets around stars and the gamma ray bursts. The solar system has also been studied easily, and this included the Eris and Pluto.
Through a small window in the universe, the HST was able to detect images by the use of patches in the sky. Astronomers were able to learn about new galaxies that were far away. During this period, the study of MACS0647-JD was possible through the improved HST camera. The SCP 06F6 that is a non-standard item was discovered by the HST in the year 2006 (Dalcanton 45).
There have been tremendous studies that pertain to the studies on astronomy data through the use of the HST. This has led to various reviewed journals being published together with various conference proceedings. Research papers based on the evidence from the Hubble have more citations currently compared to those produced outside the space telescope.
In conclusion, the HST has been helpful to astronomers and many other scientific research writings. However, the cost of running the research work, and the actual use of the medium has been expensive. The telescope has been found to be 100 times expensive compared to others that perform similar functions. It is expensive to build and maintain while operating either on the ground or at space. It has improved significantly and has been able to provide clear images even when faint objects are examined.
