The National Aeronautics & Space Administration's Hubble Space Telescope has spotted a previously obscure dwarf galaxy, which has been named as Kks3. Located as many as 700 million light-years away, near the Hydrus constellation, Kks3 has a stellar mass equivalent to just 1/10,000 of our Milky Way.

KKs3 lacks features like the spiral arms that are found in Milky Way. It can not produce any new stars because of lack of the raw materials/gases required for the formation of new stars. Scientists are of the view that the raw materials might have been stripped away by nearby larger galaxies, such as Andromeda.

The team of researchers, led by Russia's Dimitry Makarov, found Kks3 while mapping a group of fifty galaxies that are situated in the Milky Way's neighborhood. It is quite hard to locate a dwarf galaxy due to the presence of the endless stream of cosmic data collected from a huge number of observatories located on ground and in space, which researchers have to analyze.

The researchers managed to locate the isolated Kks3 with the help of the Hubble Space Telescope's Advanced Camera for Surveys (ACS). The discovery was made in August this year.

Professor Makarov and his colleagues, who are primarily interested in uncovering dwarf galaxies' objects in a bid to understand the formation of galaxies in the universe, are now hopeful that they would be able to find more dwarf galaxies in the future as new & advanced instruments have made the job a lot easier.

The discovery appeared in the most recent edition of the Monthly Notices of The Royal Astronomical Society.
