The National Aeronautics and Space Administration (NASA) had launched the Hubble Space Telescope in 1990 into low earth orbit. Since then, the telescope has been providing essential information to scientists. Now, by using its Advanced Camera, scientists have discovered another dwarf galaxy. The same group of scientists had discovered a dwarf galaxy, KKR25, in 1999. According to them, the earlier found dwarf galaxy is second dwarf galaxy after KKR25.
According to the team of Russian and American scientists, the newly discovered dwarf galaxy has been spotted at a distance of about of 7 million light years from earth. It was spotted by Russia's Special Astrophysical Observatory in Karachai-Cherkessia.
The scientists have named the galaxy 'KKs3'. According to them, the galaxy is among those 50 galaxies that are known as 'Local Group'. The group contains both earth's Milky Way and a spiral galaxy, Andromeda. The size of the galaxy is much smaller than Milky Way. It is approximately one-ten thousand of earth's Milky Way.
The galaxy doesn't have any spiral arm, the scientists said. The galaxy also doesn't have any dust or gas, the substances that are required to create new stars, they added. According to Dimitry Makarov, a team member of the Hubble team, it is not an easy task to find dwarf galaxies like KKs3 even in the presence of telescopes like the Hubble Space Telescope. The scientists have built up a map of earth's neighbourhood to make the task easier, Makarov added.
Makarov said, "It may be that are a huge number of dwarf spheroidal galaxies out there, something that would have profound consequences for our ideas about the evolution of the cosmos".
