Which of the following statements is incorrect about Milky Way?

Detailed Solution for Olympiad Test Level 2: Our Earth and Universe- 1 - Question 7
  • About 90 percent of the mass in the Milky Way’s gravitational field is made up of dark matter, so the luminous stars gas and dust of the galaxy are embedded at the center of a huge, roughly spherical dark matter halo of more than a million light-years across. There is an object at the center of the Milky Way called Sagittarius A-star which emits much more X-rays and radio waves than expected for a star-sized body. 
  • Much of the Milky Way galaxy is blocked from our view on Earth due to the barriers created by dusty gas clouds blocking much of the light. Using infrared, microwave, and radio astronomy techniques, it is possible to penetrate much of this dusty fog. However, that too allows us only detect only half of the stars and gas.
