The milky way is potentially much larger than was believed up to now. Scientists have discovered that the arms of the milky way is not flat, but wavy. In addition, the Milky way, not to 100,000 light-years wide, but is about 150,000 light-years.
This is the Milky way as something else in each other than scientists until now assumptions, write the researchers in their article in The Astrophysical Journal. The researchers compare the structure with the waves that arise when you use a stone throws him in the water, reports ScienceDaily. The ripple in the arms of the Milky way would come may be because the smaller galaxies by the Milky way and were, in addition, that wavering effect caused.
The scientists, from the United States, the United Kingdom and China, came the waves on the track by deviations in the positions of stars. It is still unknown whether there are still waves lie behind the now well-known arms of the Milky way.
