 Previous hubble name: LST(Large space Telescope)
- 
  
  
- 
  
  Primary mirrors were fixed by COSTAR
- 
  
  
- 
  
  Shows unimaginable number of galaxies in the universe
 (No specific month or day)
- 
  
  Space Telescope Imaging Spectrograph , Near Infrared Camera and Multi-Object Spectrometer were installed so that Hubble could take detailed pictures of our universe and detect black holes, and watch the universe in the infrared wavelengths.
- 
  
  Upgraded any wornout or outdated equipment on Hubble
- 
  
  Sharper view, new steering equipment, fix infrared vision, and install a more efficient power system
- 
  
  The hubble is tracing the earliest stages of the first galaxies.
- 
  
  
- 
  
  To fix old stuff that didnt work properly anymore and Installe Wide Field Camera 3 (WFC3) and the Cosmic Origins Spectrograph. They had to remove the Wide Field and Planetary Camera 2 to make space for the more advanced wide field camera 3.
- 
  
  Hubble has taken the deepest image of the universe ever taken in near-infrared light.
- 
  
  hubble uncovered a prehistoric population of compact and ultra-blue galaxies that had never been seen before. It allows astronomers to see the galaxy as it was thirteen billion years ago
- 
  
  Hubble found what astronomers believe is the most distant object ever seen in the universe. The objects light traveled 13.2 billion years to get to hubble. This object is a compact galaxy of blue stars that existed 480 million years after the Big Bang
- 
  
  Using the slitless grism on Hubble Space Telescope's Wide Field camera 3 to explore farther parts of our universe. Astronomers found supermassive black holes growing in very small galaxies.
- 
  
  hubble detected a distant Type Ia supernova, the farthest stellar explosion that can be used to measure the expansion rate of our universe .
