The Tucana Dwarf galaxy is located about 3.6 million light-years from the Local Group's center of mass, which is quite far from theand other galaxies. Researchers have suggested that the Tucana Dwarf galaxy may have receded to this secluded corner of the cosmos after a close encounter with a larger galactic neighbor,, roughly 11 billion years ago. The gravitational forces created by such an interaction would have flung the smaller companion to a further distance, according to the statement.
"Dwarf galaxies could be the early ingredients for larger galaxies, and with older stars residing in such an isolated environment, analyzing them can help trace galaxy formation back to the dawn of time," NASA officials said in the statement. and Wide Field and Planetary Camera 2. Studying the galaxy's structure, composition and stellar evolution will help researchers better understand the epoch of reionization, when the first stars and galaxies formed billions of years ago.
