Carina Dwarf
The Carina dwarf galaxy is a dwarf galaxy in the constellation early morphological type keel of the boat (Latin Carina ). In 1977, it was with the UK Schmidt telescope at Siding Spring Observatory by the research group Cannon et al. discovered ..
Properties
As one of the satellites of the Milky Way, the Carina dwarf away at a speed of about 230 km / s The galaxy, also known under the names of ESO 206- G20 or PGC 19441 appears to have formed only several billion years after the other satellite galaxies of the Milky Way. The oldest stars in the Carina dwarf galaxy have only a relatively young age of less than 7 billion years. This makes it a relatively young galaxy in comparison with its parent galaxy of the Milky Way, which already has an age of 13.6 billion years and thus is almost as old as the universe itself
The Carina dwarf galaxy has likely have a quite remarkable, complex star formation history in spite of their somewhat shorter development. At least three distinct phases of star formation could be identified for the dwarf in the keel of the ship. Its proximity to the Milky Way they will be so severely deformed by tidal forces that the dwarf galaxy already drags a tail of gas, dust and stars behind.
