A new scientific study indicates that Milky Way Galaxy is bigger than the previous assumptions of astronomers.
Recently, astronomers stated that original estimate size of the Milky Way should be altered. Earlier, scientists believe that the width of Milky Way is nearly 100,000 light years. However, the latest research rebuffs the previous notion with an addition of 50,000 light years.
An international group of researchers re-examined astronomical data through Sloan Digital Sky Survey. The study indicates that the disk of Milky Way is not arranged like a flat plate. It behaves like stagnant water when a pebble is thrown into it. It immediately contract and emits waves from the point of impact.
Yan Xu, a scientist at the National Astronomical Observation of China, discussed the research in detail. He notifies that re-analysis of the stream of stars that surrounds the galaxy open new window in the size of Milky Way Galaxy. It reveals that ring of stars that surrounds the galaxy is actually a part of it.
As per the previous assumption, number of stars present in the Milky Way reduces at a speed of 50,000 light years away from the center. In comparison, the ring of stars appears at 60,000 light years after those stars.
The paper is available in detail in the Astrophysical Journal.
