Solution
Most of the mass of the Milky Way seems to exist in the form of dark matter out in the Halo.
Here's a step-by-step explanation:
-
The Milky Way, like most galaxies, is made up of stars, gas, dust, and dark matter.
-
Population I and II stars, hydrogen gas in the disk and spiral arms, and the black hole in the Galactic Center all contribute to the mass of the Milky Way. However, these components do not account for the majority of the mass.
-
Observations of the rotation curves of galaxies, including the Milky Way, suggest that there is a significant amount of mass that we cannot see directly. This unseen mass is referred to as dark matter.
-
Dark matter does not emit, absorb, or reflect light, making it invisible. However, we can detect its presence through its gravitational effects on visible matter.
-
In the Milky Way, dark matter is distributed in a roughly spherical halo around the galaxy. This halo extends well beyond the visible components of the galaxy.
-
Therefore, most of the mass of the Milky Way seems to exist in the form of dark matter out in the Halo.
