The Hubble Space Telescope has discovered 252 faint Dwarf Galaxies located in three clusters and it will contribute immensely in knowing the formation of the Universe. Scientists had poring over data collected by the NASA/ESA Hubble Telescope and discovered 252 faint Dwarf Galaxies within three distant Galaxy clusters. The discovery will give scientists a look into the condition of early universe some 600 to 900 million years after the Big Bang.
The Hubble Space Telescope is looking at some of the earliest galaxies which have been formed a few hundred million years after the Big Bang. These primordial galaxies were formed 600 million years after the Universe was formed and played a vital role in shaping the cosmos. The cloudy remnants of Hydrogen gas was also burnt away giving a clearer picture of the galaxies.
The universe has passed through a number of stages during its evolution and one of these is the mysterious re-ionization epoch which ended some 700 million years after the Big Bang.
Hubble employed gravitational lensing caused by massive clusters of galaxies which warp space and time to observe these faint galaxies which normally will not be visible in its own conventional lenses. Gravitational lensing allowed astronomers to look deeper into universe than ever before. Johan Richard from the Observatoire de Lyon, France observed that these images were fainter than any other images ever uncovered by Hubble in its deepest observations.
These pictures come almost 25 years after Hubble was launched in 1990 to fathom the vast mysteries of space and Universe. It is still breaking all barriers and giving images which could never be seen from any Earth based telescope.
