Milky Way is constantly swallowed objects (Figure).

<P Align=center> Keywords: galaxy swallowed objects </ P> <P align=center> </ P> <P align=center> drawn by the computer through the galactic halo of the huge "stream" </ P> .<P> According to foreign media reports, Australian astronomers have launched a new observation confirmed that the Milky Way where we are likely to be a "greedy brutality galaxy." .They explained that some of the Milky Way halo is in the range, located in the Sagittarius dwarf galaxy is constantly "falling" in the Milky Way. .World Scientific reports </ P> <P> astronomers noted that the halo surrounding the Milky Way is surrounded by some of the old stars near the galactic disk. .Objects falling into the halo dwarf galaxies are from the neighbors (in the constellation, the quality is only one ten thousandth of the Milky Way.) .Interestingly, these objects continue to flock to the Milky Way is like a huge "stream" will be the Galaxy cut off from the surrounding halo. .</ P> <P> Stephen Kohler carry out the study, who found this great "stream" the length of the foot 15 million light years, much longer than previous estimates. .To find out which types of objects, Kohler led the research team analyzed more than 1.5 Photo Star photos. .Were selected as markers of scientists is known as RRLira stars. .In this star, scientists can easily measure the distance around the object and the Earth. .</ P> <P> analysis of the galaxy through its gravitational effects of celestial bodies around the situation, the scientists will be possible to measure the exact shape and mass of the galaxy. .Similar gravity also helps to identify those from the dark matter (the mass occupied most of the total mass of the Milky Way) emitted electromagnetic waves. .World Scientific reports </ P> </ p>.
