SOLAR SYSTEM

Detailed explanation-1: -Hubble’s Impact Thanks to Hubble’s observations, astronomers have traced the evolution and formation of galaxies, discovered that most galaxies contain supermassive black holes, and mapped the presence of the mysterious dark matter that makes up most of the universe’s mass and structure.

Detailed explanation-2: -The Hubble Space Telescope was launched in 1990, one of its major goals being to pin down the Hubble Constant. In 2001, a team studying supernovae with Hubble, along with ground-based optical telescopes, established a rate of 72 ± 8 km/sec/Mpc.

Detailed explanation-3: -In the 1970s NASA and the European Space Agency took up the idea and proposed a 3 metre space telescope. Funding began to flow in 1977 and it was decided to name the telescope after Edwin Powell Hubble who had discovered the expansion of the Universe in the 1920s.

Detailed explanation-4: -Views from outer space telescopes are clearer than those from Earth-based telescopes. Earth-based telescopes have a greater range of light detection. Human error is reduced by the use of the Hubble telescope. The Hubble telescope is used to examine events that cannot be explained.

Detailed explanation-5: -Edwin Hubble: The man who discovered the Cosmos.
