New observations Milky Way

New observations and measurements have shown that the Milky Way, the galaxy we live in, may be bigger than we thought.
It's shaped like a deformed 150 thousand-light-year-rpm vinyl record.
Furthermore, up to now we thought there was a dwarf galaxy near the Milky Way that was part of the Great Dog (Canis Major) constellation. But we were barking up the wrong tree.
