NASA’s Hubble Space Telescope has uncovered a mysterious solitary dwarf galaxy known as UGC 4879.

NASA’s Hubble Space Telescope has uncovered a mysterious solitary dwarf galaxy known as UGC 4879. 
•    The galaxy is smaller and messier than its cosmic cousins and lacks the majestic swirl of a spiral or the coherence of an elliptical. 
•    The galaxy UGC 4879 is very isolated and consists of a scattered drizzle of stars. It about 2.3 million light years away from its closest neighbour, Leo A which is about the same distance as that between our Milky Way and the Andromeda Galaxy. 
•    The galaxy has not interacted with any of surrounding galaxies that makes it an ideal laboratory for astronomers to study star formation by interactions with other galaxies. 
•    The scientific studies of this solitary galaxy UGC 4879 will provide ample scientific study material for astronomers looking to understand the complex mysteries of star birth throughout the universe. 
•    It will especially help astronomers to study amount of star formation in the first 4 billion years after the Big Bang and followed by a strange 9 billion-year lull in star formation.
•    HST was launched in 1990 as an international cooperation space project between NASA and European Space Agency. 
•    It is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. 
•    Its science operations are conducted by Baltimore based Space Telescope Science Institute (STScI). 
•    It is located in low Earth orbit outside the distortion of Earth’s atmosphere that allows it to take extremely high-resolution images.
