Take an interactive tour of the solar system, or browse the site to find fascinating information, facts, and data about our planets, the solar system, and beyond. However, there remains debate over whether it represents a disrupted dwarf galaxy or in fact a variation in the thin and thick disk and spiral arm populations of the Milky Way. The collision between these two galaxies is of great interest to astronomers since this event might reflect the probable fate of our Milky Way galaxy and the Andromeda galaxy. The Milky Way passes through Canis Major, and as such, several open clusters lie within its borders. WR 7 is also exciting the ring nebula NGC 2359, also known as Thor’s Helmet.

Several of the globular clusters found in the Milky Way are also thought to have come from the Canis Major dwarf, whose ultimate fate is to merge with the Milky Way over the next billion years or so. Until recently, however, this dwarf galaxy lay unobserved behind the dust and gas in the disk of the Milky Way. These distances put it even closer than the previous record holder, the Sagittarius dwarf galaxy discovered in 1994, which lies 50,000 and 80,000 light-years from the galactic center and Earth, respectively.
